During the summer of 1993, a network seismological stations was installed over period 7 weeks around eastern Gulf Corinth where sequence strong earthquakes occurred during 1981. Seismicity lies between Alepohori fault dipping north and Kaparelli south is related to both these antithetic faults. Focal mechanisms show normal faulting with active plane at about 45° for The aftershocks 1981 earthquake recorded by King et al. (1985) were processed again similar results. In contrast, observations...
On 30 October 2020 11:51 UTC, a Mw=6.9 earthquake struck the offshore region north of Samos Island, Greece, in Gulf Ephesos/Kuşadasi, causing two fatalities and 19 minor injuries at as well 115 casualties over 1,030 Western Turkey. Preliminary results indicate that mainshock occurred on north-dipping normal fault, with focal mechanism 270º/50º/-81º. The selection fault plane is supported by evidence uplift western 10 cm subsidence northernmost edge central part island. distribution relocated...
Abstract The National Observatory of Athens data center for the European Integrated Data Archive (EIDA@NOA) is national and regional node that supports International Federation Digital Seismograph Networks related webservices seismic waveform coming from southeastern Mediterranean Balkans. At present, it serves eight permanent broadband strong-motion networks Greece Cyprus, individual stations Balkans, temporary aftershock deployments, earthquake engineering experimental facilities.

The Corinth Rift in Central Greece has been studied extensively during the past decades, as it is one of most seismically active regions Europe. It characterized by normal faulting and extension rates between 6 15 mm yr−1 an approximately N10E° direction. On 2013 May 21, earthquake swarm was initiated with a series small events 4 km southeast Aigion city. In next days, seismic activity became more intense, outbursts several stronger magnitude 3.3 3.7. seismicity migrated towards east June,...
Due to early implementation of public health measures, Greece had low number SARS-CoV-2 infections and COVID-19 severe incidents in hospitalized patients. The National Kapodistrian University Athens (ΝΚUA), especially its health-care/medical personnel, has been actively involved the first line state responses COVID-19. To estimate prevalence antibodies (Igs) against among NKUA members, we designed a five consecutive monthly serosurvey randomly selected consenting volunteers. Here, present...
Abstract We investigate a seismic crisis that occurred in the western Gulf of Corinth (Greece) between December 2020 and February 2021. This area is main focus Rift Laboratory (CRL) network, has been closely monitored with local seismological geodetic networks for 20 yr. The 2020–2021 evolved three stages: It started an Mw 4.6 event near northern shore Gulf, opposite Aigion, then migrated eastward toward Trizonia Island after 5.0 event, eventually culminated 5.3 ∼3 km northeast Psathopyrgos...
Cephalonia, located in the middle of central Ionian Islands, has been affected by destructive earthquakes during both instrumental and historical period. Despite fact that it is widely studied from several scientific viewpoints, limited research conducted so far regarding earthquake-triggered landslides (ETL) related susceptibility. In context present study, an inventory with 67 ETL 11 occurred 1636 to 2014 presented. Given this record, study further examines susceptibility exploiting 10...
The Arkalochori village in central Crete was hit by a large earthquake (Mw = 6.0) on 27 September 2021, causing casualties, injuries, and severe damage to the infrastructure. Due absence of apparent surface rupture initial focal mechanism solution seismic event, we initiated complementary, multi-disciplinary research combining seismological remote sensing data processing, followed extensive field validation. Detailed geological mapping, fault measuring accompanied with tectonic analysis,...
Abstract The Galaxidi earthquake that occurred in the Gulf of Corinth on 18 November 1992 was not followed by a noticeable aftershock sequence, fact also observed for 1965 Eratini event same area. temporary network 35 stations we installed 5 days after mainshock did help to identify cluster activity related mainshock. In section across epicentral zone, focal mechanism and distribution few aftershocks define plane dipping north, consistent with nearby Helike fault. We propose an asperity...
Seismicity in the Ionian Sea (W. Greece) is mainly generated along Cephalonia–Lefkada Transform Fault Zone (CLTFZ) central Ionian, and on northwestern termination of Hellenic subduction margin south. Joint pre-, co- post-seismic ground deformation seismological analysis performed at broad area, aiming to homogeneously study spatiotemporal evolution activity prior after occurrence strong (M > 6) earthquakes during period 2014–2018. The 2014 Cephalonia (Mw6.1 Mw5.9) were a faulting system...
We present a physically based methodology to predict the range of ground-motion hazard for earthquakes along specific faults or within source volumes, and we demonstrate how incorporate this into probabilistic seismic analyses (PSHA). By 'physically based,' refer syntheses derived from physics an understanding earthquake process. This approach replaces aleatory uncertainty that current PSHA studies estimate by regression empirical parameters with epistemic is expressed variability in...
The Athenet network is the of Seismological Laboratory National and Kapodistrian University Athens. We present geophysical investigation that has been carried out at six seismological stations for their site characterization. More specifically, location each station, four methods have out: Seismic Refraction Tomography (SRT), Multichannel Analysis Surface Waves (MASW), Horizontal to Vertical Spectral Ratio (HVSR) technique, Electrical Resistivity (ERT). applied survey provided important...
Probabilistic Seismic Hazard Assessment (PSHA) was carried out for the administrative region of Attica (Greece). Peak Ground Acceleration (PGA) and Velocity (PGV) values were calculated return periods 475 950 years five sub-areas covering entire region.
