The largest aftershocks so far are magnitude 4.4 that took place at 01:14 UTC and 4.7 that took place at 08:55 UTC this morning. This earthquake swarm is taking place on a complex fault area that is highly active. There is also big question what effect this earthquake swarm is going to have on other faults in the area. There is a risk that this earthquake swarm is going to start other earthquake swarms in nearby faults. Uncertainty level has been declared for area from Sau\u00f0\u00e1rkr\u00f3kur to Raufarh\u00f6fn at least. This is the largest earthquake in this area since the year 2002 and 2005. But both this years there was a magnitude 5.0 earthquakes in this area.<\/p>\n<p><a href=\"http:\/\/icelandgeology.net\/wp-content\/uploads\/2013\/04\/130402_1430.jpeg\"><img loading=\"lazy\" decoding=\"async\" src=\"http:\/\/icelandgeology.net\/wp-content\/uploads\/2013\/04\/130402_1430.jpeg\" alt=\"130402_1430\" width=\"540\" height=\"416\" class=\"aligncenter size-full wp-image-3553\" srcset=\"https:\/\/icelandgeology.net\/wp-content\/uploads\/2013\/04\/130402_1430.jpeg 540w, https:\/\/icelandgeology.net\/wp-content\/uploads\/2013\/04\/130402_1430-300x231.jpeg 300w\" sizes=\"auto, (max-width: 540px) 100vw, 540px\" \/><\/a><br \/>\nThe earthquake activity in TFZ.
