Today (27-March-2014) an earthquake swarm took place in Gr\u00edmsfjall<\/a> volcano. This activity is connected to current minor glacier flood from Gr\u00edmsv\u00f6tn glacier lake that is now taking place. The glacier flood it self is an minor and is about the same size as an glacier flood from Gr\u00edmsv\u00f6tn glacier lake in November-2012.<\/p>\n

Harmonic tremor has been increasing in Gr\u00edmsfjall volcano following this glacier flood. The leading idea is that the glacier flood is creating this high frequency harmonic tremors. This idea however remains unconfirmed at current time.<\/p>\n

At present time there is nothing to suggest that an eruption has or is about to start in Gr\u00edmsfjall volcano. However Gr\u00edmsfjall volcano is unpredictable and highly active when it comes to eruptions. If an eruption starts in Gr\u00edmsfjall volcano it might do so without an warning. Earthquake activity in Gr\u00edmsfjall volcano would increase sharply just before the eruption would start as was the case before the eruption in 2011 (covered here<\/a>). More detailed monitoring can of Gr\u00edmsfjall volcano and other volcanoes in Vatnaj\u00f6kull glacier can be found here<\/a> (Icelandic).<\/p>\n

There however has been a minor issue with my Google Adsense account. An issue that has so far not yet been resolved by Google. Once its resolved I am going to go trough the process of getting my account approved again. I was too detailed back in January when I closed down my Google Adsense account. I hope to have advertisements back before some volcano erupts in Iceland.<\/p>\n","protected":false},"excerpt":{"rendered":"
