“…The 26 December 1861 earthquake is included in several studies focusing on large earthquakes of the Gulf of Corinth (e.g. : Mouyaris et al, 1992;Lekkas et al, 1996;Caputo et al, 2015). Researchers' quite uninterrupted attention was drawn by the presumed 12 to (1825-1884), who at the time of the earthquake was the Director of the Observatory of Athens.…”

“…Some authors consider the 1861 surface rupture the effect of the reactivation of the 373 B.C. Helike fault (Sebrier, 1977;Mouyaris et al, 1992;Caputo et al, 2015). Others, following de Ballore (1924), interpreted "this crack nothing more than the surface expression of a large-scale slumping and spreading of the valley material" (Richter, 1958;Antonopoulos, 1980, who also re-published the simplified map from Richter).…”
Section: A Veritable Western Gulf Of Corinth Earthquake: 26 December mentioning
The area of the Western Gulf of Corinth around the city of Aigio (Achaea, NW Peloponnese, Greece) represents an international pilot site for continuous monitoring and multidisciplinary research on earthquake processes. In the framework of the ANR-SISCOR Corinth Rift Laboratory (CRL) project (2011-2014), a thorough reappraisal of the five largest (M>6) 18th-19th century earthquakes was performed, namely those of 14 May

“…However, considerably less attention was given in faults located in regions with poor historic and low instrumental seismicity. Consequently, the study of these faults is then required for improving the seismic hazard assessment (Lafuente Caputo et al, 2015), especially in densely populated areas (Zygouri et al, 2015;Grützner et al, 2016).…”
“…Recurring linear morphogenic earthquakes that rupture the Earth's surface and repeatedly offset preexisting landforms, like slopes, river channels or banks, alluvial fans, etc., commonly produce cumulative scarps over geological timescales [38][39][40][41]. Scarp height is typically used as a proxy for minimum coseismic vertical displacement [42] and indicates the deformation style and magnitude of the earthquake(s) associated with the analysed fault.…”
Section: Postseismic Activity Along the Trgmentioning
On 3 March 2021, an important seismic sequence started in northern Thessaly, Greece. The Damasi Seismic Sequence (DSS) deformed the western sector of the Tyrnavos Graben, which includes a major blind normal fault and the Titarisios River Graben (TRG). In this contribution, we provide fieldwork observations across the TRG and satellite radar interferometry of the faults controlling the graben. In addition, we provide a map of the active faults exposed in the TRG and palaeoseismological analyses of the Mesochori Fault, which together contribute to unravelling the seismic history of the area. DInSAR provides clear evidence of the Mesochori Fault surface rupture during the main shocks, while our palaeoseismological analyses document a long seismic history of the fault, with a mean recurrence interval of 1.0–1.5 ka and a mean slip per event of ~15 cm for the last four events reactivating the scarp. Quantitative geomorphological analyses based on real-time kinematic (RTK) measurements with global navigation satellite system (GNSS) receivers and data from UAV flight campaigns also provide evidence of postseismic activity across the Mesochori Fault. Based on these results showing that (at least) the Mesochori Fault has been reactivated several times in the latest Quaternary the seismotectonics of the TRG are discussed.
