For the past few hours activity has been dropping, there is however nothing that says activity is not going to increase again. Such activity is common in this area, but it&#8217;s impossible to know for sure what happens next. At the moment there is nothing to suggest that volcano activity is the source of this activity. That might change but I think it is unlikely to be the case at the moment, regardless of what the future has in store.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Today at 01:11 UTC (13-October-2013) an earthquake swarm started on the Reykjanes peninsula.
