Today on 6-May-2017 a magnitude 4,4 – 4,5 earthquake hit South Icelandic Seismic Zone (SISZ) at 12:08:58 UTC. This earthquake was felt over a wide area, a magnitude 3,3 earthquake also took place around one minute after the main earthquake. The earthquake took place on a fault that might have last moved in the year 1623 or 1624, as is detailed here<\/a>. Current earthquake activity does classify as a “Su\u00f0urlandsskj\u00e1lfti”, only earthquakes with magnitude above 5,5 are classified as such. This is regardless a strong earthquake activity in SISZ for a long time now.<\/p>\n

More aftershocks are expected in this are for the next few hours to days. It is difficult to know if this means there is going to be a larger earthquake activity at this location or nearby. It’s always a chance, but it is not possible to know that for sure.<\/p>\n
