Abstract

The following two earthquakes occurred in Greece during 2019: First, a Mw5.4 earthquake [1] close to Preveza city in Western Greece on 5 February and a Mw5.3 earthquake [2] 50km East of Patras on 30 March. Here, we present the natural time analysis [3] of the seismic electric signals (SES) activities [4,5] that have been recorded before these two earthquakes. In addition, we explain how we can identify the occurrence times of these two earthquakes by analyzing in natural time the seismicity subsequent to the SES activities.
