A Dataset of Peak Ground Acceleration (PGA) Estimates for the Aigio–Lykoporia Zone, Greece

A Dataset of Peak Ground Acceleration (PGA) Estimates for the Aigio–Lykoporia Zone, Greece Authors Angelos Zymvragakis (National and Kapodistrian University of Athens) — ORCID Ioannis Spingos (National and Kapodistrian University of Athens) — ORCID George Kaviris (National and Kapodistrian University of Athens) — ORCID Description The dataset contains simulated Peak Ground Acceleration (PGA) data from Probabilistic Seismic Hazard Assessment (PSHA) modelling in the Aigio–Lykoporia Zone (ALZ; Northern Peloponnese, Greece). PSHA was performed through the Cornell-McGuire approach (Cornell, 1968; McGuire, 1976). Files The dataset contains PGA for a Return Period (RP) of 475 years, i.e. 10% probability of exceedance in 50 years, in easily parsable CSV format. The following file is included: alz_intensity_measurement_levels.csv Field description: node_id: Node identifier (string). node_longitude_deg: Longitude in decimal degrees (WGS84) (float). node_latitude_deg: Latitude in decimal degrees (WGS84) (float). pga_475_cmps2: Peak Ground Acceleration for a 475‑year return period, in cm/s2 (float).
