Seismic activity of Montenegro and its surroundings
for year 2010 
|
During the year 2010, Montenegro Seismological Observatory, using seismic network containing 13 stations, recorded moderate seismicity and at the end of the year increased seismic activity on the Montenegro territory. At that period, 435 earthquakes, under 1.2 magnitude were recorded totally. During the daytime 240 of total number of earthquakes occurred and 195 at the night. An average number of earthquakes per month were 36 and the maximum – 304 (70 % of all occurred earthquakes) was registered during December as a result of increased seismicity at Pluzine and Brajici regions.
Last year was characterized by incrised seismicity on the northwestern part of Montenegro, in a wider zone of the accumulation lake for the Piva Hydroelectric Plant. Starting from the 2nd of December until end of the year, Montenegro Seismological Observatory recorded 195 earthquakes, under 1.2 magnitude in this area. Occurred sequence of earthquakes is a typical manifestation of induced seismicity, caused by the effect of water mass of artificial lake Piva, on surroundings rocks. Accumulation was in its maximum for a longer time period, so releasing of seismic energy through smaller tectonic activity and consequent earthquakes is driven by strong hydrostatic pressure on surroundings rocks. |

The epicenters of recorded earthquakes at the Montenegro territory and its surroundings (2010) |
|
The strongest earthquake generated from this seismogenic source occurred on the 21st of December at 09:56 local time, with Richter magnitude of 4.0, on 3 kilometers east from Pluzine. Earthquake felt with intensity of VI degrees on the Mercalli Scale in the area of the accumulation, within 10 kilometers distance and with intensity of V degrees on the Mercalli Scale in Zabljak and area within 20 kilometers distance. Accerometric stations in Niksic (NKME), Herceg Novi (HCY), Podgorica (PDG) and Dračevica (DRME) registered this earthquake and time history are given on the pdf report. |
