文摘

The Vértes Hills are one of the most active seismic regions in Hungary. An \(\hbox {M}_\mathrm{L}~=~4.5\) magnitude earthquake shocked this area near to Oroszlány on January 29, 2011. The mainshock was followed by about four hundred aftershocks, and their magnitude varied from \(\hbox {M}_\mathrm{L}~=~-0.6\) to \(\hbox {M}_\mathrm{L}~=~3.5\) . Despite of the large number of aftershocks, the seismotectonic interpretation is very difficult because these earthquakes occurred in the vicinity of quarries. The waveform similarity analysis was proven a successful method to separate earthquakes and explosions, and revealed plus information about the aftershock sequence.
