Abstract:
A map of epicenters of 411 earthquakes with magnitude Mw >= 2.5 that occurred from 2017 to 2019 in Bulgaria and surroundings (sector outlined by latitude = 41o – 44.5o N and longitude = 22o – 29o E) registered by NOTSSI is presented. Analysis is done on the distribution of the events through time and space, magnitude and depth. The events frequency progression is analyzed for the whole studied period and then compared with each year separately. Generalized analysis is proposed as to what can contribute to variations in the data for the studied period. Catalog of earthquakes with magnitude Mw >= 3.5 is applied.
