The largest earthquakes have gone up to ML2.0 (automatic SIL data), with the focal depth of ~4 km. So far around 20 earthquakes have been recorded by the SIL system that Icelandic Met Office runs. This morning the earthquake swarm has quieted down a bit. But it is hard to know if it is over or not. But this area of Kr\u00edsuv\u00edk volcano has been having a lot of micro-earthquakes swarms over the past few weeks. This has been followed by a uplift in the volcano (inflation). But that did start early last year after a short period of deflation.<\/p>\n<p>Other then this, it remains quiet in Iceland volcano and earthquake wise.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Since Week 52 in the year 2010 there have been strange earthquakes between B\u00e1r\u00f0arbunga volcano and Gr\u00edmsfjall volcano.
