La región septentrional del territorio central cubano constituye un prisma acrecionario del Cretácico Cenomaniense-Eoceno superior temprano, compuesto por la imbricación del margen continental de Bahamas, de fragmentos de corteza oceánica antigua y de restos del arco volcánico cretácico. La formación y consolidación morfoestructural del relieve actual responde a dos etapas principales del desarrollo geotectónico, una de compresión tangencial, laramídico, de grandes desplazamientos horizontales, y otra de reordenación neotectónica de la estructura y del paleorrelieve alpino, con predominio de movimientos verticales oscilatorios, a partir del Eoceno superior temprano. Esto generó en el relieve, morfoestructuras de horst escalonados en mantos de sobrecorrimientos verticalizados y cuñas tectónicas, de zócalo plegado en bloques, de bloques escalonados en monoclinales, y otros tipos. Los movimientos tectónicos recientes de estas morfoestructuras, según las nivelaciones reiteradas, indican una estructura en bloques y muestran un carácter diferenciado, con gradientes generalmente suaves entre los mismos, aunque fuertes en ocasiones, a lo largo de las líneas geodésicas de precisión Remedios-Holguín y Minas-Camagüey, con valores extremos de sus velocidades relativas anuales de +3.5 mm/año (bloque de llanuras bajas Esmeralda-Jaronú) y de -10.0 mm/año (graben San Miguel de Baga).

Living a place means first of all reading it, understanding it, assimilating it. This is even more evident in the case of a particular natural environment where the possibilities of land use are limited. Looking at a map of the Alps, it becomes clear how the morphology has conditioned the methods of settlement and exploitation of the places. In an attempt to read and interpret the transformation of the Alpine territories, the Architetti Arco Alpino association has initiated a review of projects, from which it emerges that today there exist very different cultural, political, social and economic contexts. The result are two almost opposite phenomena. In some places the mountains have been abandoned, which has led to the risk of losing their important architectural heritage. The interventions are therefore aimed at enhancing the existing structures and constructing new buildings capable of becoming a reference for the redevelopment of entire villages. In other places, a harmonic balance between human presence and territory has been largely exceeded. Here, the objective is to put a stop to further land development, aiming to enhance the quality of the existing buildings and implementing an aesthetic and formal research that is capable of becoming an economic value and an element of cultural identification. Taking into account the various “cultural horizons” and reference regions, it becomes clear that South Tyrol has historically maintained close ties with North Tyrol and the neighbouring Swiss cantons. Contemporary architecture is commonly seen as an asset today, not only among experts, but also among the general population. On the other hand, the relations with Austria’s and Slovenia’s Eastern Alpine territories have less effect. The research seems to be the work of a limited number of professionals. In the Western Alps, cross-border relations with France and Switzerland have a stronger cultural and linguistic root, but perhaps the presence of large massifs difficult to cross has prevented a closer relationship and a dissemination of common construction methods. Crossing national and international administrative boundaries, the Alps can continue to be a place of passage, of confrontation and of cultural, linguistic, economic and also architectural exchange.

In order to study the freezing front characteristics of alpine tunnels under the condition of wind flow field and relying on the Osaka Mountain tunnel in Qinghai Province, the physical model test of an alpine tunnel was built. By using the Surfer software combined with the laboratory test data, the radial and longitudinal temperature variation trends of the tunnel were obtained, and the overall temperature vector graph of the tunnel was simulated; the radial and longitudinal evolutionary laws of a freezing front in an alpine tunnel under airflow conditions were systematically analyzed, and the radial and longitudinal governing equations of a freezing front in the tunnel model under airflow conditions were proposed. The results show that: With the decrease of the test air temperature, the thermonuclear area in the surrounding rock gradually shrinks, the frozen area of surrounding rock at the bottom of the arch gradually increases, and the frozen area of surrounding rock at the top of the arch gradually expands to the interior of the mountain. The influence degree of ventilation on the longitudinal and radial temperature distribution of the tunnel is obvious, and the greater the wind speed, the greater the influence degree. In particular, the fluctuation range of the longitudinal temperature distribution of the tunnel is more extensive under the influence of ventilation. The freezing front distance in the inverted arch area is the largest, and the expansion distance of the freezing front in the wall foot area is obviously higher than that in the vault; the variation of the longitudinal freezing front at different positions of the tunnel shows parabolic attenuation and with an increase in tunnel depth, the trend of freezing front gradually eases and becomes stable and disappears; the three radial regions of the freezing front and the longitudinal quadratic parabola governing equations can predict the specific distribution characteristics of the freezing front at different depths of the tunnel.

The present article concerns the problem of the contradiction between striving to maintain in the designed and implemented buildings of large volume in Polish area around the Tatras, in which it is justified to use current building technologies, including prefabricated buildings construction methods, and the need to continue the characteristic architectural forms of Tatra region. The demonstrated examples of architectural formation of buildings constructed during the interwar period-made for the needs of International Winter Olympics FIS, they used of the typical patterns of farms for the Alpine region. Such on example provides the evidence for the cultural pressure of a new function, i.e. skiing. Such an influence cannot be easily and consistently opposed in terms of logic performance of Tatra style current examples.

The Rupicaprini originated during the Miocene in Asia and dispersed during the late Miocene-early Pliocene, the Villafranchian, and the middle Pleistocene. Rupicapra and Oreamnos spread respectively to Europe and to North America in the middle Pleistocene. The Villafranchian Procamptoceras may be considered to be the closest known form to Rupicapra's ancestor. Rupicapra evolved during the middle and late Pleistocene in west Eurasia. At the beginning of the Würm glaciation the two closely related species R. pyrenaica and R. rupicapra were in existence. The former was already geographically split into Spanish-Pyrenean and central-southern Apennines groups, while the latter species ranged from the Caucasus to the Alpine Arch. R. pyrenaica shows more conservative features and possibly differentiated directly in western Europe from older representatives of the genus that migrated to western Europe in the middle Pleistocene. The cold-adapted Alpine chamois may have differentiated in eastern Europe and then migrated west-ward because of the advent of dry climates in the east Mediterranean and Pontic regions. The Alpine chamois failed to spread to the warmer southernmost regions of Europe that became a refugium area for R. pyrenaica. This dispersal hypothesis explains the morphologic, biometric, electrophoretic, and behavioral differences among modern chamois populations.

The study of the objects LaTène type found in middle-eastern alpine region (Trentino Alto Adige-Südtirol, Engadina, North Tirol, Voralberg and Villach basin) is aimed to a better comprehension of the complex net of relationships established among the Celts, settled both in the central Europe territories and, since the IV century b.C., in the Po Plain, and the local populations. The ancient authors, who called the inhabitants of this area Raeti, propose for this territory the usual pattern according to which, the population of a region was formed consequently to a migration or was caused by the hunting of pre-existing peoples. The archaeologists, in the last thirty years, recognized a cultural facies typical of the middle-eastern alpine territory during the second Iron Age, and defined that as Fritzens-Sanzeno culture (from the sites of Fritzens, Inn valley, and Sanzeno, Non Valley). The so-called Fritzens-Sanzeno culture spread out without breaks from the material culture of the final Bronze Age and the first Iron Age. This local substratum, characterized by a ceramic repertoire strongly standardized, by peculiar architectural solutions and by a particular typology of rural sacred places (Brandopferplätze), accepted, above all during the second Iron Age, the strong influences coming from the Etruscan world and from the Celtic one (evident in the presence of objects of ornament, of glass artefacts, of elements of the weaponry and of coins). The objects LaTène type become, with different degrees of reliability, important markers of the relationships existing between the Celts and the Raeti, although the ways of interaction (cultural influence, people's movements, commercial exchanges, gifts among élites etc.) is not still clear. The revision of published data and the study of unpublished materials allows to define a rich and articulated picture both to chronological level and to territorial one.

Une étude palynologique a été conduite sur de nombreuses localités du Miocène (21-8 Ma) de l'arc alpin européen, avec comme objectif principal la reconstitution de la végétation et, en conséquence, du climat et de son évolution. Une dégradation de la végétation et du climat, confirmée par la quantification des paramètres climatiques à partir des données polliniques, a été observée au cours du Miocène en Europe et interprétée comme la conséquence du refroidissement climatique progressif survenu sous l'effet conjoint d'une glaciation antarctique et de la surrection alpine. On a pu caractériser à partir ds résultats polliniques un gradient thermique et pluviométrique latitudinal en Europe occidentale et des fluctuations climatiques en relation avec les cycles de Milankovitch. Les paléoaltitudes des reliefs proches des bassins sédimentaires investis montrent la surrection progressive de l'arc alpin pendant le Miocène moyen. L'analyse des kystes de dinoflagellés a permis l'établissement d'une biozonation pour la Paratéthys Centrale (Bassin Pannonique)

Abstract Mycorrhizal symbiosis is generally advantageous for plants in nutrient-poor soils. Arcto-alpine areas are relatively nutrient-poor, but abundantly inhabited by non-mycorrhizal species. Possibly, mycorrhizal symbiosis is not favoured due to the harsh climatic conditions and the short growing season, which constrain the photosynthetic gain and growth of the arcto-alpine plants. This hypothesis was theoretically evaluated by assuming that optimal mycorrhizal colonization maximizes the net carbon gain of the host plant. In addition, the prevalence of arbuscular mycorrhizal (AM) and dark-septate endophytic (DSE) fungi along an altitudinal gradient was studied in the field, and their effects on the plant performance were tested in the laboratory. In the model, the photosynthetic nutrient use efficiency (PNUE) had a key role in determining whether mycorrhizal strategy would be optimal for the plant net carbon gain. The model generated several colonization patterns depending on possible changes in PNUE and soil nutrient concentrations along altitudinal gradients. Field studies indicated that species-level colonizations do not yield a consistent pattern along the altitude except for fine endophyte, which increased along an altitudinal gradient. In a high-alpine field site root fungal colonizations were rare. Seasonal shifts in colonizations in low-alpine conditions were not found. DSE fungi were common root-associates in the field. In the laboratory, AM had a positive impact on the performance of Gnaphalium norvegicum at 15°C, but not at 8°C. DSE-inoculation did not colonize the roots, but it had a positive impact on seedling performance, which may be due to the saprophytic activity of the fungus in the substrate. Additionally, mycorrhizal inoculum was found to decrease the performance of a non-mycorrhizal plant in a competition experiment. Species-level mycorrhizal colonization patterns may differ from community-level pattern along altitudinal gradients and the relative abundance of different fungal symbionts may change along with the altitude. The performance of mycorrhizal plants in high-alpine conditions may be decreased due to several factors e.g. low temperature constraints on plant and fungal physiology and allocation, soil disturbances and low availability of inoculum. Climatic constraints for plant photosynthesis may thus affect the mycorrhizal colonization patterns in arcto-alpine conditions, but are not necessarily the primary cause for lower performance of mycorrhizal plants at higher altitudes.

L'Arc en Maurienne (Savoie) présente à l'état naturel tous les caractères d'une rivière torrentielle à forte pente, à l'hydrologie contrastée, aux transports solides abondants. Depuis le XIX siècle, des interventions anthropiques massives ont transformé profondément le fonctionnement du système fluvial : un endiguement insubmersible sur les deux tiers du cours d'eau, l'assainissement de la basse vallée par colmatage et drainage, des travaux de correction torrentielle dans les bassins versants affluents, le développement des équipements hydroélectriques. Maîtrisé, l'Arc est à l'origine de la transformation de l'espace mauriennais en couloir industriel. Les aménagements de la rivière entraînent des perturbations profondes de l'hydrologie : la modification des débits et des rythmes des écoulements ordinaires, la suppression des crues de forte fréquence et la création d'un régime-usine artificiel. Le domaine dans lequel l'anthropisation est la plus caractéristique et la plus lourde de conséquences en terme de gestion est celui de la morphologie fluviale. Le transit des matières en suspension n'est plus entièrement assuré ; la charge de fond, pour l'essentiel d'origine torrentielle, continue de parvenir dans le talweg tandis que l'affaiblissement de la puissance de la rivière a supprimé sa capacité d'évacuation. La tendance à l'exhaussement et à l'engorgement du lit constitue un trait original dans l'évolution actuelle des rivières alpines. Dans ce contexte, les grandes crues, non modifiées par les équipements hydroélectriques, deviennent des épisodes paroxysmaux dont les effets sont amplifiés. Le cumul des perturbations anthropiques conduit à l'élaboration d'une dynamique fluviale d'un type nouveau, artificielle et tronçonnée.

Cette thèse cible l'évolution Néogène de la branche sud de l'arc alpin occidental. Une approche multi-méthodes associant études de terrain, sismotectonique et thermochronologie basse température y met en évidence un régime tectonique complexe ainsi qu'une évolution morphologique et structurale originale au sein de l'arc. La fracturation s'organise autour d'un faisceau d'accidents NW-SE, à jeu principalement dextre, accompagnant la courbure de l'arc et commandant structure et morphologie. Par ailleurs, à l'échelle des massifs, une structuration en failles normales conjuguées NE-SW traduit une extension parallèle à la chaîne. D'autres failles normales traduisent une extension perpendiculaire à la chaîne. L'inversion des données microtectoniques a permis de caractériser des régimes de paléocontraintes décrochant et extensif. L'absence d'une chronologie cohérente à l'échelle régionale suggère que ces régimes ont coexisté. Je propose que ces régimes constituent deux extrêmes d'un régime de contrainte unique variable, résultant de l'interférence entre un champ de contraintes extensif, à tendance multidirectionnelle et propre à la partie interne, surépaissie de la chaîne, et un champ de contraintes décrochant à transpressif commandé aux limites de la chaîne. L'analyse sismologique montre que l'arc interne subit actuellement un régime transtensif en zone Briançonnaise et un régime purement extensif en Zone Piémontaise, plus interne. La direction d'extension reste proche d'E-W, comme plus au nord à la latitude du Pelvoux, et indépendante de la courbure de l'arc. La caractérisation du régime extensif actuel en termes de directions tangentes ou radiales à l'arc est donc ici inadaptée. La Zone Externe présente un régime globalement transpressif à nuancer puisqu'elle est également affectée par de l'extension dans sa partie la plus interne. Je propose une corrélation entre la zone subissant l'extension et la zone d'épaisseur crustale maximum. Ce modèle s'inspire et étend celui proposé par [Delacou et al., 2004]. Il favorise un processus d'extension lié à un effondrement gravitaire de la chaîne. La structure arquée concerne surtout la croûte supérieure, les structures plus profondes étant plus linéaires. Ce découplage vertical des structures est probablement hérité du poinçonnement syncollision oligocène, responsable de la formation de l'arc interne. Il peut expliquer qu'au Néogène le découplage tectonique entre arc interne en extension et zone externe en transpression ne réactive pas, près de la surface, l'ancien front chevauchant de l'arc interne, comme c'est le cas plus au nord au sein de l'arc. Quelques nouvelles données thermochronologiques (traces de fission dans l'apatite), replacées dans une synthèse des données existantes, confirment que les Alpes sud-occidentales ont connu une évolution structurale et morphologique originale au Néogène. Les zones internes présentent un refroidissement final homogène et rapide dès la fin de l'Oligocène. Le saut d'âge entre zone externe et zones internes, récemment mis en évidence à la latitude du Pelvoux, est confirmé dans l'ensemble de la branche sud de l'arc. Il témoigne de l'inversion du front chevauchant des zones internes peu de temps après le paroxysme de la collision. Je relie l'exhumation rapide des zones internes de la branche sud à la forte érosion d'une cordillère alpine axée sur les zones internes au front du poinçon apulien. La quantification de l'évolution du relief à partir du système traces de fission sur Apatite a été testée sur la base de deux transects échantillonnés dans les massifs du Pelvoux et Dora-Maira. Les relations âges-altitudes à différentes longueurs d'onde permettent d'estimer un taux d'exhumation moyen de 0.4km/Ma pour le Pelvoux au cours des 7 derniers Ma, et de 0.1Km/Ma pour Dora-Maira au cours des 20 derniers Ma. Pour ces deux massifs, aucune évolution probante du relief n'est mise en évidence. On souligne dès lors le manque de résolution du système apatite pour quantifier l'évolution du relief. Une synthèse des résultats permet de proposer que la déformation soit le résultat d'un équilibre instable entre l'étalement de la chaîne sous l'effet des forces de volume et la cinématique complexe de l'Apulie qui intègre à la fois une composante en translation et une composante rotationnelle.

A partir de nouvelles observations structurales, nous proposons un nouveau modèle cinématique pour la Zone Houillère Briançonnaise, située au-dessus du front briançonnais (structure majeure des Alpes occidentales). Ce modèle est conforté par l'inversion des données de déformation finie, interpolées et visualisées à l'aide du modeleur 3D GOCAD (ENSG-LIAD Nancy). Les données de déformation finie ont été acquises par l'utilisation d'algorithmes d'analyse d'images, semi-automatisées au cours de ce travail. L'inversion a été effectuée à l'aide du logiciel FaultPack (Université Rennes 1). Le modèle cinématique qui résulte de ce travail se décompose en trois évènements principaux suivis d'un épisode extensif. L'évènement D1 traduit très probablement la subduction de l'océan piémontais au cours de laquelle, restant dans le prisme d'accrétion tectonique, la Zone Houillère subit un écaillage vers L'ouest alors qu'une partie de la Vanoise est entrainée dans la subduction. Au cours de D2, la subduction de la Vanoise se bloque et cette zone est alors charriée sur la Zone Houillère puis elle l'emboutit. L'évènement D3 est associé à l'indentation de la croûte européenne par le poinçon adriatique. Cette indentation est, entre autre, la cause de la surrection des Massifs cristallins externes qui réactive une surface correspondant au Front Briançonnais originel (décollement précoce D1 et/ou structure D2) en faille normale. Le rebroussement résultant de la surrection des Massifs cristallins externes produit une structure de type roll-over. L'évènement extensif D4, continuum plus superficiel de D3, provoque alors le basculement de tout l'édifice vers l'Ouest

Famous for the late 14th-century revolt known as Tuchinaggio, the Canavese area, in north-western Piedmont, provides significant information concerning the relationship between lords and subjects in a longer time span. By analysing a wide range of sources (pastoral visitations, chronicles, court and notarial records, statutes), the essay examines the domini-homines dialectic in the first half of the 14th century: in the Canavese Alpine valleys various degrees of institutional consolidation of communities can be outlined, identifying a process of growth common to communities in the entire Alpine Arc.

The present-day major relief features of western Europe are to a great extent determined by the underlying geological structures, either passively or actively. To get a comprehensive picture of their morphological evolution and interrelations, this chapter provides an overview of the spatial and temporal characteristics of the larg-escale tectonic framework of the continent. After having described the west European landscape at the end of the Palaeozoic, to which time the oldest preserved landforms date back, an outline of the Mesozoic and Cenozoic history of the major tectonic domains follows. Finally, some denudation estimates highlighting the relationship between tectonics, erosion, and the resulting relief, will be discussed. The three main influences on the present-day topographic patterns are those of the Alpine orogeny, the Cenozoic West European rifting, and the imprint of Variscan structures. They combine within a regional stress field determined by the Africa–Eurasia collision and the Alpine push as well as the mid-Atlantic ridge push. Since the end of the Miocene, this stress field is characterized by a fan-shaped distribution of SHmax along the northern border of the Alpine arc. This gives way to a more consistent NW–SE to NNW–SSE direction of compression further from the chain (Bergerat 1987; Müller et al. 1992). Topographically, western Europe may be roughly divided into a series of belts parallel to the Alpine chain. The Alpine chain culminates in a number of peaks exceeding 4,000 m in elevation (4,810 m at Mont Blanc) but the average altitude is in the order of 2,000 m. To the north, the mountainous Alps are bordered by the Molasse foredeep basin whose surface makes an inclined plane descending northwards from c.1,000 m to c.300 m near the Donau River in the Regensburg-Passau area. To the north-west, the Molasse basin narrows between the Alps and the Jura Mountains and is occupied by several extended lakes inherited from Quaternary glacial activity. Next to the Molasse basin in the north and west is a wide belt of recently more or less uplifted areas between 200 and 1,000 m in elevation (and locally in excess of 1,000 m in the French Massif Central and the Bohemian massif).

ABSTRACT The Cenozoic accretionary complex in the Calabrian Arc, southern Italy, contains hectometric- to kilometric-scale exposures of basalt, gabbro, and serpentinite that have been interpreted as dismembered fragments of Alpine Tethys ocean crust because of their incomplete nature with respect to the traditional view of a complete ophiolite sequence. We present new geologic mapping, geochemistry, and geochronology of one of these units at Timpa di Pietrasasso near the town of Terranova di Pollino in the Basilicata region that exposes Jurassic Tethyan pillow basalt and chert that are separated from gabbro and serpentinite by a fault. The gabbro in the footwall is Permian in age, indicated by U-Pb zircon ages of 284 ± 6 Ma, 293 ± 6 Ma, and 295 ± 4 Ma, linking it to gabbros that underplated continental crust after the Permo-Carboniferous Variscan Orogeny. The gabbro first underwent amphibolite-facies metamorphism, then developed a greenschist-facies mylonitic foliation near the fault surface that is crosscut by undeformed Jurassic-aged dikes of Tethyan origin, indicating that deformation is early Tethyan or pre-Tethyan in age. The underlying serpentinite is tectonically interleaved with blocks of Variscan lower crust, indicating that the missing upper plate of the extensional detachment complex was continental in origin. These features indicate that the Timpa di Pietrasasso unit preserves a low-angle detachment fault that developed in a hyperextended continental margin of the Alpine Tethys.

ABSTRACT Two contrasting field relationships may reflect different tectonic settings of subduction initiation preserved in orogenic belts. “Hot” subduction initiation assemblages include a large ophiolite unit (up to kms thick, extending tens to hundreds of km along strike) with supra subduction zone (SSZ) geochemical affinity that structurally overlies a thin (&lt;500 m thick) sheet of high-pressure (HP), high-temperature (HT), primarily metamafic rocks called a metamorphic sole. The ophiolite generally lacks burial metamorphism and includes variably serpentinized peridotite at its base. The sole structurally overlies subduction complex rocks made up of oceanic materials (igneous part of oceanic crust and overlying pelagic sedimentary rocks, and clastic sedimentary rocks of trench fill affinity) and/or passive margin assemblages; some of the subduction complex may be metamorphosed under HP-low temperature (LT) conditions (such as blueschist facies). The field relationships suggest initiation of subduction within young (&lt;15 My) and “hot” oceanic lithosphere and that the sole represents the first slice(s) of material transferred from the subducting to upper plate. Examples include the Neotethyan and northern Appalachian ophiolites and units beneath them, and the Coast Range ophiolite and subjacent Franciscan subduction complex of California. “Cold” subduction initiation assemblages lack SSZ ophiolite and island arc components and a metamorphic sole. Instead, the upper plate above the subduction complex is made up of continental lithosphere that last experienced significant heating during a passive-margin forming rift event. The protoliths of the rocks subducted were &gt;70 My in age at the time of subduction initiation. The HP-LT subduction complex is composed of slices of continental crust and oceanic crust representing parts of a hyperextended continental margin. These field relationships suggest initiation of subduction along a continental margin within old (“cold”) hyperextended continental lithosphere. Examples include the Apennine subduction zone, exposed in Calabria, Italy, and the Alpine orogenic belt, both remnants of the Alpine Tethys.

The Mediterranean is the westernmost part of the global-scale Alpine-Himalayan orogenic belt which stretches from Spain to New Zealand. The landscapes of the region have a long and complex history that includes both horizontal and vertical crustal movements and the creation and destruction of oceans. This began with the break up of the super-continent Pangea around 250 Ma, which generated the Tethys Ocean—the forerunner to the present-day Mediterranean Sea. Collision of the African and European tectonic plates over the last 30 Ma led to the destruction of the Tethys Ocean, although a few remnants of its geology are preserved within the eastern Mediterranean. It is the collision of Africa and Eurasia, and the associated tectonics that have been largely responsible for generating the Mediterranean Sea, its subsequent history, and the landscapes that surround it. This collisional history progressively reduced the connectivity of the Mediterranean Sea with surrounding marine bodies by closing and restricting marine gateways. During the Miocene, for example, the Mediterranean basin became completely isolated from surrounding marine bodies in what is known as the ‘Messinian Salinity Crisis’. This period saw major changes to the regional water balance leading to evaporation and draw-down of the Mediterranean Sea. This had profound impacts on all aspects of the physical geography of the region including the climatology, biogeography, and geomorphology and its legacy can be seen across the region today. The more recent Quaternary geodynamics of the Mediterranean have generated an area which includes a complex mixture of zones of plate subduction of various ages and stages (Figure 1.1b). The modern Mediterranean includes zones of active subduction associated with volcanic activity—such as the Calabrian arc—and older zones of now quiescent subduction such as the Betic-Rif arc. There is a wide range of seismic activity associated with these regions from deep (600 km) to shallow (<50 km) and ranging in magnitude up to 8.0Mw (earthquake moment magnitude; a quantitative and physically based scale for measuring earthquakes).
