Constant earthquake activity has been in SISZ over the week and it has been ongoing for the past weeks, none of the earthquakes have been large, with almost all of them being less then magnitude 1,0. Largest earthquake in this swarm had the magnitude of 2,5.<\/p>\n
B\u00e1r\u00f0arbunga volcano<\/strong><\/p>\n For most part earthquake activity in B\u00e1r\u00f0arbunga<\/a> volcano was normal this week, with regular earthquake swarms taking place in the usual places. The most interesting earthquake this week took place under Tr\u00f6lladyngju, it was only magnitude 0,7, but it was on depth of 26,2 km.<\/p>\n Earthquake swarm has been taking place all week in Her\u00f0ubrei\u00f0. Earthquake swarms are common in this area and often have magnitude 3,0 earthquakes or larger. The earthquake swarm is ongoing when this is written.<\/p>\n Reykjanes ridge<\/strong><\/p>\n A magnitude 3,4 earthquake took place deep on the Reykjanes ridge this week. The earthquake was not felt and there might have been more than one earthquake. My geophone in Heklubygg\u00f0 shows more than one earthquake one hour after the magnitude 3,4 earthquake happens.<\/p>\n![\"151011_1755\"](\"http:\/\/icelandgeology.net\/wp-content\/uploads\/2015\/10\/151011_1755.png\")
