Magnitude 3,9 earthquake in SISZ last night

Yesterday (8-May-2014) a magnitude 3,9 earthquake took place in SISZ (South Icelandic Seismic Zone). This earthquake was felt over all of south Iceland, no damage took place following this earthquake. This earthquake appears to have been on N-S fault in SISZ. Only few minor aftershocks took place following this earthquake. I don’t know why that is and this lack of aftershocks is interesting.

It is possible to see any future earthquake activity here on my geophone station at Heklubyggð. The geophone station at Böðvarshólar is not updating due to failed 3G transmitter the area that I use to connect that geophone station to the internet. I hope it gets fixed soon. People can also used the website of Icelandic Meteorological Office to watch for any future earthquake activity in SISZ.
