Abstract

A ten-year complete seismological database is evaluated in the present work. These data are provided for events with magnitude ML ≥ 1.0, which have occurred in Eastern Greece and, more specifically, in Kos Island. Several selection criteria are applied and, hence, a catalog of the seismological records is compiled. Detailed big data (seismological, tide gauge, geodetic stations, accelerometers, etc.) of this region are used and processed in this work. The database consists of approximately 35,000 three-component broadband seismograms from 1198 digitally recorded events. It covers the last ten years of measurements, including records from the 20 July 2017, ML 6.2, Kos Island, Greece event. The seismological communities can either use this database to conduct new research or improve already existing seismic hazard studies in the region.

Highlights

In the broader area of Greece prevails a complex seismic tectonic regime characterized mainly by the fault of Northern Anatolia [1,2,3,4,5] and from the Europe Africa subduction zone [6,7] along the Greek arc [8,9,10]
The Aegean Sea Plate is a small tectonic plate located below southern Greece and western Turkey in the eastern Mediterranean Sea
The seismological database we present has a total of approximately 35,000 threecomponent broadband seismograms

Summary

Introduction

In the broader area of Greece prevails a complex seismic tectonic regime characterized mainly by the fault of Northern Anatolia [1,2,3,4,5] and from the Europe Africa subduction zone [6,7] along the Greek arc [8,9,10] This fact creates an intense deformation both along these active zones and in the broader area, resulting in a significant number of small and intermediate magnitude earthquakes. Kos in the Eastern Aegean (36.6574◦ < Lat < 37.0902◦ and 26.8533 < Lon < 29.9025◦ ) These results can help researchers to understand the earthquake’s seismogenic structure and provide great, useful basic information for further specific studies and hazard assessment. It is the first time that such a 10-year period analysis with the latest state-of-the-art software has been applied in Greece
