Update on Hekla volcano status

Here is an update on Hekla volcano. First of, for the moment the inflation in Hekla volcano is deflating at the moment. This is following the same pattern as before last time this did happen. But that does not mean this might not happen again soon. For the moment, nobody knows what exactly is going on inside Hekla volcano as there are no earthquakes following this inflation period. The magma that is on the move down there is most likely moving deep down in the crust also, as Hekla volcano does not have shallow magma system that I know of (or is known of anyway).

What did happen inside Hekla volcano was most likely an dike intrusion somewhere in the volcano system. This dike intrusion did not create any earthquakes, that suggests to me that it was travelling trough an old dike system already in place inside Hekla volcano system. This is most likely to happen again in Hekla volcano, if that starts an eruption is hard to know for sure.

In regards to possible ash cloud from eruption in Hekla volcano is impossible of know for sure now what happens in next eruption. There might be an ash cloud, but then again there might not be. All that can be done is to wait and see what happens in the next days, weeks or years.

The GPS movement of Hekla volcano. The inflation and the deflation can clearly be marked here. There is an inflation spike around 2011.45 on this plot. But this did also happen in April/May I think (but it might be wrong). Daily updated chart can be found here. Copyright of this picture belongs to Icelandic Met Office.

It is also important to notice that Civil Emergency Authority (Almannavarnir) in Iceland advice against it travelling up to Hekla volcano at current time. Since an eruption can start in Hekla volcano without any warning at all and the maximum time that people have evacuate the mountain is from 1 hour and up to 1 hour and 30 min. No more then that. Being on top of Hekla volcano when an eruption starts is deadly to everyone. If you want to go up to Hekla volcano. Please let somebody know about and have an fully charged mobile phone with you at all times. As the Civil Emergency Authority send out an SMS message to all mobile phones in the area around Hekla volcano if an eruption is starting (I think they do that).
