Identification of Antrophic Activity Interference in the Seismic Catalogue for Banat Region

Abstract

Abstract Banat region is one of the most active zones in terms of crustal seismicity in Romania. Even though the active seismic monitoring started from early XXth century, the data sets got more performant with the development and expansion of the seismic network monitoring in the late 1970’s. One particularity regarding seismic data acquisition is that in many cases anthropic activity, such as mining and quarry exploitation, interferes with natural seismicity. Our aim is to bring forward a series of data extracted from the ROMPLUS catalogue to identify the anthropic interference. To this we propose a method based on multiple discrimination criteria, such as local time of event occurrence, magnitude, location in respect with the nearest exploitation site, depth and P-wave input analysis (polarity and waveform). Identifying and filtering the anthropic events from the catalogue will result in a better imaging and characterizing of the natural seismic phenomenon in Banat region improving this way the regional seismic hazard assessment.
