The 2020–2021 Seismic Crisis in the Gulf of Corinth

The dataset includes earthquake and waveform correlation information related to the 2020–2021 seismic crisis in the Gulf of Corinth, Greece. corinth_gulf_2020_2021.csv contains the relocated earthquakes that occurred during the sequence, along with corrected local magnitudes (ML corrected). The original ML values from routine analysis were found to be systematically over- or underestimated depending on the stations used. The correction methodology is described in Papadimitriou et al. (2022). File format:Year, Month, Day, Hour, Minute, Seconds, Latitude, Longitude, Depth, ML, ML (corrected), Event ID cc_values.csv includes the differential travel times and waveform cross-correlation coefficients used in the identification of repeating earthquakes, as described in Bountzis et al. (2025). File format:Event1 ID, Event2 ID, Station ID, Differential Time (s), Correlation Coefficient (CC) Event IDs refer to entries in the last column of corinth_gulf_2020_2021.csv. Station IDs are listed in the accompanying file stations.txt.
