Full textFrom Fustel de Coulanges to M. H. Hansen, the Greek city has never ceased to intrigue historians. In ancient times, Corinth was one of the most powerful cities in the Greek world. Studies on the Corinthian city are often old, written in English and focused on the oldest periods of ancient times.Literary sources provide a better understanding of the wealth and the diversity of the Corinthian pantheon. However, these writings are not enough and the researches must based on other disciplines ; archeology, epigraphy, numismatic, for instance. A joint analysis of these sources provides an overview of Corinthian religious life between archaic and imperial times, presents the region's shrines and temples, describes and analyses the cults and rituals practiced in these places

Full textThe aim of the research project is to better understand Corinthian trade in the Greek and the Eastern Mediterranean world through the analysis of its exports volume and the local and temporal variations while trying at the same time to clarify its economic, political or social mechanisms. This study is mainly based on the figured Corinthian pottery that spread during most of the Archaic Age from the 9th to the 6th century BC. The geometric pottery (non-figured) and the amphora are also used in the analysis as much as possible, to sharpen our study, as well as other exportation products less important in terms of quantities such as bronze horses. The whole of the exports is studied with the imports which were far fewer in order to put the Corinthian trade into the larger setting of the Greek and Mediterranean trade and to have a better understanding of the nature of the economic relations binding Corinth to its trading partners. A comparison with a wider corpus of documents enables us to put the study into perspective and to reinforce the broad features of the Corinthian trade in the Eastern Mediterranean region. Every big stage of this trade (Geometric, Protocorinthian, Corinthian) is subdivided into thirteen periods allowing us to follow the economic activities along thirteen generations of men. Finally, the study of each type of shapes enables us to follow the evolution of tastes and markets during the whole Archaic Age

Full textThis work focuses on limestone construction-stones used in archaeological context, in monumental construction from the 7th to the 1st century B.C., in continental Greece, more precisely on sites in the eastern Gulf of Corinth. Unlike marbles, limestones and their associated quarries have rarely been the subject of archaeometric and systematic study, and confusions about the geological nature of the rocks are common. The main questions addressed here are therefore: (1) what types of stone are used? (2) where do these stones come from? (3) why were these stones chosen? This thesis is based on extensive fieldworks, which provide an inventory of construction-stones and ancient quarries. It is combined with the study of geological contexts and an important historiographical study, as work on archaeological site is limited (working on remains, without sampling). The Gulf of Corinth is an active quaternary graben: on the southern margin, syn-rift deposits are outcropping because of the uplift of the Peloponnese. These formations were exploited by Greek builders and provided the majority of the pôros, a generic term used since Antiquity to speak about recent unconsolidated rocks of various types (sandstone, travertine, tuff, shell limestone). Some of these facies were imported, but the majority of the sites exploited local resources (hard limestone, conglomerate or sandstone, depending on the geology): a low diversity of stones is observed in each site (<5 facies), and more than 80% of the volume of stone is represented by one single local facies. Finally, to understand the choice of stones by the Greek builders, a study of the petrophysical properties of different materials was carried out. It seems that the density was the only important physical property. One site shows exceptional characteristics: the sanctuary of Delphi, where more than twenty facies have been identified: the local facies (limestone, breccia and travertine) represent a relatively small volume. Half of the facies are allochthonous and represent more than 50% of the volume of stone used: the oolitic dune of Corinth, the limestone of Megara, black stones, Cycladic and Attic marbles, but also various sandstones whose origin remains to be defined. These new data inform us about the exchange of stones at the scale of the Gulf in Antiquity, and suggest areas for future research on the study of limestone used in construction

Full textBetween 440 B. C. And 96 A. D. , Corinth’s territory met several evolutions marked by the will and the political choices of the city. The independent Corinth fought against Athenian, Spartan, Theban and Macedonian hegemonies. But, with the decline of its liberty and its control on its territory, the city fought resolutely on the Macedonian side against Achaeans and Romans, then blindly on the Achaean side against the Romans. The latter finally destroyed her and dismantled its territory with Sikyonian help after 146 B. C. Even if the ex-Corinthian territory could have been centuriated, it is only in 44 B. C. With the birth of the Colonia Laus Iulia Corinthiensis that revive the political, juridical and territorial existence of Corinth. Organized by a centuriation, the Corinthian plain offered a better viability for their farmers. The Flavians who rebuild the city and reorganize its territory at the end of the first century will bring about the last important change

Full textRivers behaviour during early rifting can significantly impact on syn-rift sedimentation and the distribution of subsidence. During normal fault growth, existing rivers can be diverted toward subsiding zones. They can respond to footwall uplift either by reversing their flow or by incising into uplifting zones. Long-lived river systems and their stratigraphic record in rifts are poorly documented, not only during early fault propagation and linkage processes but also during successive migrating phases of fault activity. We investigate the interactions of major antecedent rivers with a growing normal fault system and the implications for facies distributions, both on a basin scale and at the scale of individual normal fault blocks. Along the southern margin of the western Corinth rift (Greece), the Plio-Pleistocene fluvial and deltaic successions are investigated. Syn-rift deposits are preserved in a series of uplifted normal fault blocks (10–20 km long, 3–7 km wide). Detailed sedimentary logging and high resolution mapping of the syn-rift deposits document variations of alluvial architecture across the basin and enable to define lithostratigraphic units. Magnetostratigraphy and rare biostratigraphic data are used to date and correlate the alluvial succession between fault blocks. Burial ages were tentatively determined using cosmogenic isotopes 10Be and 26Al produced in situ in quartz grains. Based on the correlation model, we reconstruct the evolution of the early western Corinth rift between about 3.6 and 1.8 Ma. (1) The transverse and antecedent Kalavryta river system flowed and deposited across a series of active normal fault blocks. (2) This river system was inherited from the Hellenide mountain belt and supplied high volumes of coarse sediments from the onset of extension. (3) As depocentres enlarged through time, the fluvial deposits progressively filled palaeorelief. A continuous braided plain developed above active buried faults and no significant consequent drainage system developed between the narrow fault blocks. (4) The main fluvial axis of the antecedent drainage persists through time and controlled facies distribution. (5) The length scale of facies transitions is greater than, and therefore not related to fault spacing. Here, along-strike subsidence variations in individual fault blocks represent a secondary contributor to the alluvial architecture. (6) The zones of maximum subsidence on individual faults are aligned across strike, parallel to the persistent fluvial axis. This implies that long-term sediment supply and loading influenced normal fault growth. Sediment supply largely outpaced local hangingwall subsidence and overfilled the early rift basin. The river system terminated eastward where small deltas are built into a shallow lake that occupied the central Corinth rift. During this time, another river system built fan deltas along the southern margin, recording diachronous deepening of the basin. The behaviour of antecedent rivers is also studied at the scale of a relay zone, that developed later in the rift history between two growing fault segments. During the Middle to Late Pleistocene, the relay zone captured the antecedent Krathis River, which deposited prograding Gilbert-type deltas. Transfer faults record progressive linkage and basinward migration of accommodation along the ramp axis, while marine terraces record diachronous uplift in their footwalls. Although early linkage occurred, the main normal faults continued to propagate until final connexion. For the first time a reconstruction of the linkage phase is presented over a period of ca. 0.5 Myr. Throughout this linkage history, the Krathis River continued to flow across the relay zone. Again, this emphasizes the role of antecedent rivers in supplying sediments and controlling the location of the major depocentres along the rift margins

Full textGPS data collected in the Corinth rift during eleven camapigns between 1990 and 2001 provide velocities of 57 points with ~1. 5mm/yr. Peloponnissos moves at 30mm/yr to the N215°E with respect to the stable Europe. Extension across the rift is accommodated in a narrow band off-shore. Its rate increases from east to west and is 16mm/yr near Aigion. Both sides of the rift behave as a rifid clockwise rotating blocks with rates of 7#0. 5°/Myr and 2. 8#0. 8°/Myr respectively for the northern and southern blocks. The strain accumulation accross the major faults located along the southern coast of the Corinth gulf is less than 1mm/yr. This implies long recurrence periods for large earthquakes on these faults. At the western and eastern ends of the rift the deformation is more diffuse. The resulting velocity field allowed us to constrain the comparison between the old triangulation coordinates and new GPS coordinates at 224 pilars of the old greek tringulation network analysis of the coseismic and interseismic vertical movements in the gulf of Corinth has been carried out with a large interferograms database. The presence of atmospheric contributions in SAR interferograms represents the main limit for the detection of ground deformations. A methodological approach is presented to reduce at both global and local scales the tropospheric contributions in the interferograms. It first requires the refined knowledge of the permanent scatterers that can only be obtained from the analysis of a large population of interferograms. The correction of global scale atmospheric contribution exploits the correlation between phase and topography and the correction of local artefacts is based oncorrelation between interferograms containing one common acquisition

Full textA structural study of the southern margin of the Corinth rift shows the existence of a quaternary detachment fault, which outcrops along 150km in the northern Peloponnese, from the Saronic gulf to the Patras gulf. Its onshore part is inactive. It dips 30-35ʿN, flats northward till 0-10ʿN and progressively increases beneath the gulf. Steeper normal faults cut through the hangingwall of the detachment and progressively branched onto it. Balanced cross-sections suggest that the onshore detachment prolonged beneath the gulf in the low-angle seismological zone. Since 300ky, the Psathopyrgos, Helike and Aigion active faults transfer the slip from the detachment to the surface. The emergence of the detachment initiated from east to west 1. 7-1My ago, and is sealed since roughly 900ky. The strain has progressively migrated toward the north on several fault-system which remained active during 250-400ky. In the gulf of Patras, seismological data show that the emergence of the detachment is still active. This differential evolution is accommodated by transfer-faults and led to the 25km shift of the Patras and Corinth gulfs. A study of fault-crystallisations shows that syntectonic breccias are cemented by two generations of calcite. The first was formed with formation water at a depth of more than 1200m and the second generation was formed with meteoric-water at a depth of 500-1000m. These data allow determining an uplift rate of 1. 7-2. 5mm/y. This result is close to uplift rates determined near the coast. Dating of these calcites by the U/Th method confirms the young age of the Corinth-Patras rift. The results show that this method is a reliable way for quaternary faults

Full textA crustal strain network was installed few years ago in the western part of the Gulf of Corinth, around the city of Aigion. It acts as a complement to the seismological network of the Corinth Rift Laboratory and is devoted to the observation of possible crustal strains related to the 5 and 10 km depth local microseismicity in order to constrain the mechanical processes of the area. The research is focused on the study of the two Sacks-Evertson borehole strainmeters installed at 150 meters depth, on the north coast of the gulf. The physical features of the observed signals are studied with a particular attention, as the prediction and correction of the external forcing. This protocol is fondamental to exhibit the internal strain signature related to solid tide and seismic or aseismic events. The Monasteraki 3-component strainmeter exhibits an instrumental behaviour close to that expected in the case of a good coupling with rock. The corrections have been made under the assumption of an elastic perturbation of all the forcings. The noise level related to the strain residual signals is close to the nanostrain at short period and the instrument has a resolution around 10−8 at one-day period. The Trizonia island dilatometer exhibits a solid-porous coupling due to installation problems, which make the observed signal complicated. Due to the proximity of the marina, the instrument is sensitive to pore pressure diffusion in the rocks and so the correction is performed by considering a frequential dependance. The solid tide which lies in the residual signal seems to indicate the existence of an internal heterogeneity. This is enhanced by seismic waves observations. The internal strain signal analysis is therefore perturbated as for example the 2008 Andravida earthquake or the 2002 strain transient related signals

Full textIt follows from the study of Peloponnesian coins issued at Messene, Hermione, Pheneus, Pale, Thelpusa, Corinth, Tegea, Kaphyai (c. 5th-2nd bc) that it is difficult to distinguish Demeter from Kore : the goddesses' attributes are generally the very same (a corn wreath and, sometimes, a torch) and both of them have youthful faces. It is not clear that green corn indicates Kore (as L. Farnell told it) for this idea is based upon an allegorical interpretation of the Homeric hymn to Demeter, at variance with Pheneus'coins. Coin engravers took Peloponnesian coins and statues as models. They generally didn't care about their patterns representing Hera, Demeter or Penthesilea. The mints were very conservative (during two centuries, they issued the same faces of Demeter at Messene and at Hermione), but very stuck to youthful faces and corn crowns

Full textThe western part of the Corinth Rift in Greece is opening at about 15 mm per year, generating one of the highest deformation rates in the world, some destructive earthquakes of magnitude M>6 per decade, and high microseismic activity irregular in space and time. In order to better understand the mechanisms related to this crustal deformation and to specify the major active structures, this research work makes use of the seismological database of the Corinth Rift Laboratory from 2000 to 2015 by finely analyzing microearthquakes and their spatio-temporal evolution. The global relocation of the seismic sources and their classification into multiplets enable to refine the geometry of the faults and to identify different mechanical behaviors. The western zone, in the middle of the gulf, is affected by fluctuations of fluid pore pressures in a geological layer, resulting in microseismic swarm migrations at a velocity of about 50 m per day. The deep multiplets of the central part, near the northern coast, are persistent and appear to be triggered by episodes of slow aseismic slip along an immature detachment, which can reach the ductile crust. The low percentage of dynamic triggering by passing seismic waves suggests that the overall state of the fault system is not at the critical breaking point. The magnitude of earthquakes is correlated with the initial impulsiveness of the rupture. These results specify the dynamics of the rift deformation, the seismic-aseismic interactions, and will make possible the improvement of the seismic hazard models of the region

Full textThe Corinth Rift, in Greece, is a young and active continental rift stretching between Continental Greece and the Peloponnese. The most active part of the rift, where the subsidence has been the highest during the Late Quaternary, has been covered by the sea and forms the Gulf of Corinth. This area is prone to natural hazards, including frequent large earthquakes, tsunamis and coastal landslides. The present thesis is dedicated to the study of these processes at the western tip of the Gulf, where the earthquake hazard, in particular, is considered as very high. We have investigated the Quaternary sediments below the Gulf of Corinth floor, through seismic reflection profiling and gravity coring. First, 22 large mass transport deposits were discovered. Their estimated volumes range from 106 to 109 m3. Large mass wasting events occurred in six stratigraphic intervals, four attributed to the Holocene and two attributed to the Upper Pleistocene. Among possible preconditioning factors and triggers, the likely influence of the sediment supply is highlighted. Then, an accurate map of offshore faults is presented. The map highlights for the first time significant strike-slip component in the offshore Corinth Rift, in addition to the dominant normal strain. Three phases are proposed for the Late Quaternary tectono-sedimentary evolution of the area. During these phases, the strain was suggested to migrate northward, driving the progressive deactivation of the large south-dipping faults that controlled the subsidence in an earlier phase of the rifting. Based on the sediment cores, sedimentary events triggered by large historical earthquakes in the last 3 centuries have been looked for. The best fit between the age of the identified event deposits and large historical earthquakes is observed in the deep basin. Finally, four longer cores retrieved in this area reveal specific spatial and temporal patterns of slope failures for the last 500-1000 yr. Such pattern is interpreted as resulting primarily from changes in the frequency of strong earthquakes. From these data, a period of seismic quiescence may have occurred between ~1740 and ~1890 AD in the west of the study area, while eastward, seismic quiescence would have occurred earlier, between ~1500 and ~1700 AD

Full textThe rock slopes evolution to the instability is a complex phenomenon, because of the large scale involved, the mechanical complexity and diversity of external factors and internal stresses. The study of the Upper Tinée valley (Southern Alps) has enabled us to develop a reference model on the evolution of a rocky slope to failure. It concerns the La Clapière slope which is affected by large scale deformations (DGSD) and a rock slide located at the foot of the slope. A coupled approach based on geological and chronological data allows the elaboration of a scenario of for the period [-10. 000 years ; current] explaining the La Clapière evolution. The curve of surface displacements and the conceptual model are associated with the progressive failure mechanism. The Upper Tinée scale study shows a similar pattern with local variations under the influence of topographic and structural effects. The role of the internal dynamic on the evolution of slopes has been studied in the area of Panagopoula (Corinth gulf, the most active continental rift in Europe). A combined geological, geophysical and topographic auscultation underlines a rapid evolution of steady-state to the instability associated with a surface accommodation of deep tectonic deformations. These two extreme contexts allow us to propose alternative scenarios in terms of stress (tectonic, topographic and structural). These conclusions are applied to a zoning of the temporal proximity to the collapse at the Upper Tinée valley scale

Full textMiddle Pleistocene Gilbert-type delta and prodelta in the Rift of Corinth, Greece, are investigated combining field methods and photogrammetric 3D model to document an entire early synrift sedimentological profile. Field works document four different dynamics in Gilbert-type bottomset deposits, each one of which is characterized by a specific range of facies, facies associations and geometries: (1) the sandy-gravelly bottomset, (2) the erosional-bypass stage, (3) the fine-grained bottomset and (4) the massive-sandy bottomset. The bottomset typologies are integrated within the stratigraphic delta context. In the associated prodelta, two active sandy-conglomeratic moats are limited by a confined drift. The prodelta moat axis are perpendicular to the delta and migrate upslope. In the moat axis, a normal-to-inverse grading sequence evolution is correlated down-flow under bottom-current processes. The asymmetric drift presents a sediment-wave architecture on its long side within two sequences : (1) a normal turbidite sequence with a sharp erosional base and massive silt to shale and (2) a contourite bi-gradational sequence affected by red crust, wavy bedding, current ripples and bioturbation. New interpretations of seismic data resulting in horizon, structural, morphosedimentary, and thickness maps, for the offshore Corinth Rift, at a 100 kyr time scales document a mixed turbiditic and contouritic deep water system. The Southern slope break presents a mixed system between gravity-driven bottomset and bottom-current moats which rework and depose drifts. The Northern slope is meanly reworked by sediment-wave and perched drift which can produced plastered drifts. At 0.4 Ma, a contouritic sedimentary system dominates the Gulf of Corinth and indicates an opening at both West and East tips

Full textSince several tens of years, the assessment of local to regional seismic hazard - mainly based on seismology and tectonic analysis - is reinforced by paleoseismic data yielded by recent sedimentary archives. Based on the expertise acquired by the LGCA on the Sea of Marmara (North-Anatolian Fault) and on the South-Caribbean Plate boundary (Boconó Fault), the present work aimed to : 1. Bring a methodological contribution to the assessment of earthquake-related deposits, 2. Separate the paleo-environmental information (climate, human impact) from the paleoseismic ones, 3. Contribute to the understanding of tectono-sedimentary systems on a regional scale. Two main sites have been elected along the Egean Arc. The Corinth Gulf (Greece) and the Shkodra Lake (Albania/Montenegro boundary). A preliminary high resolution seismic reflection survey of the Cariaco Gulf (north-eastern Venezuela) is added. The two sites were chosen in order to compare two sedimentary accumulations undergoing similar historical seismicity (close to 7 in magnitude, 2 to 3 major events per century), but very different with respect to depositional depth, sedimentary processes, and accumulation rates. The records are lasting respectively 20 kyr (Corinth) and 10 kyr (Shkodra) back from Present. The use of Anisotropy of Magnetic Susceptibility was developed. For each site, the search of sedimentary traces of historical earthquakes preceded the possible extrapolation of the results back to longer periods. The Shkodra site (very shallow) did not yield significant paleoseismic archive, but well a marked climatic signal since more than 7000 years. For the Corinth site, the frequency of layers possibly related to earthquakes is compatible with regional historical data and show enhanced exportation in the depth by mass wasting during the lacustrine phase. Eustatic fluctuations effect on sedimentation were also identified. The Cariaco site displays few co-seismic disturbances visible at seismic imagery scale. Nevertheless, our results enabled to define faults systems present in the Gulf and also propose a very first chronological framework for the sedimentation

Full textThe objective of the present work is to characterize sediment supply dynamics within the Plio-Pleistocene Corinth Rift using an integrated approach based on field observations and analyses, experimental modeling and numerical modeling. Detailed sedimentological, structural and biostratigraphical studies on the southern coast of the rift provide a tectono-stratigraphic model within a well-constrained climatic and eustatic setting. Stratigraphic simulations (DIONISOS) are used to validate this model, to quantify the sediment supply and to discuss the relative role of four controlling factors on stratigraphic architecture (sediment flux, water flux, subsidence, eustasy). Finally, a geomorphological experimental approach has been developed to study the relative role of factors (rainfall, uplift rate. . . . . ) that control sediment supply and their record within the sedimentary signal

Full textSpace geodesy techniques (SAR interferometry and GNSS) have recently emerged as an important tool for mapping regional surface deformations due to tectonic movements. A limiting factor to this technique is the effect of the troposphere, as horizontal and vertical surface velocities are of the order of a few mm yr⁻¹, and high accuracy (to mm level) is essential. The troposphere introduces a path delay in the microwave signal, which, in the case of GNSS Precise Point Positioning (PPP), can nowadays be successfully removed with the use of specialized mapping functions. Moreover, tropospheric stratification and short wavelength spatial turbulences produce an additive noise to the low amplitude ground deformations calculated by the (multitemporal) InSAR methodology. InSAR atmospheric phase delay corrections are much more challenging, as opposed to GNSS PPP, due to the single pass geometry and the gridded nature of the acquired data. Several methods have been proposed, including Global Navigation Satellite System (GNSS) zenithal delay estimations, satellite multispectral imagery analysis, and empirical phase/topography estimations. These methods have their limitations, as they rely either on local data assimilation, which is rarely available, or on empirical estimations which are difficult in situations where deformation and topography are correlated. Thus, the precise knowledge of the tropospheric parameters along the propagation medium is extremely useful for the estimation and minimization of atmospheric phase delay, so that the remaining signal represents the deformation mostly due to tectonic or other geophysical processes. In this context, the current PhD Thesis aims to investigate the extent to which a high-resolution weather model, such as WRF, can produce detailed tropospheric delay maps of the required accuracy, by coupling its output (in terms of Zenith Total Delay or ZTD) with the vertical delay component in GNSS measurements. The model initially is operated with varying parameterization in order to demonstrate the best possible configuration for our study, with GNSS measurements providing a benchmark of real atmospheric conditions. In the next phase, the two datasets (predicted and observed) are compared and statistically evaluated for a period of one year, in order to investigate the extent to which meteorological parameters that affect ZTD, can be simulated accurately by the model under different weather conditions. Finally, a novel methodology is tested, in which ZTD maps produced from WRF and validated with GNSS measurements in the first phase of the experiment are used as a correction method to eliminate the tropospheric effect from selected InSAR interferograms. Results show that a high-resolution weather model which is fine-tuned at the local scale can provide a valuable tool for the tropospheric correction of InSAR remote sensing data

Full textTectonic and geodetic observations (GPS) allow us to model the present-day deformation of the Anatolia-Aegean region and its mechanical evolution. In our approach, the deformation of the lithosphere is localised on known faults, treated as dislocations in elastic half-space. We show that two tectonic processes are superposed at the lithospheric scale : The extension associated with the Hellenic subduction and the extrusion of Anatolia associated with the propagation of the North Anatolian Fault (NAF). Since the NAF entered the Aegean, the two processes interact mechanically. We show that a large process zone forms at the front of the NAF, as the lithosphere relaxes long-term elastic strains. As a result the NAF has become a transform fault for 3/4 of its length. The simple elastic behaviour of the continental lithosphere explains the mechanical balance between the rigid rotation of Anatolia and the deformation of the Aegean
