It is hard to describe this changes. But they appears to be changes in harmonic tremor levels in Gr\u00edmsfjall volcano. But they appears to be above background levels and the reason why that is a bit unclear at the moment, but I do not think that this is ice movement as I did think it was first. As this has been lasting for too long. Following this has been a slow increase in earthquakes in and around Gr\u00edmsfjall volcano. This earthquakes don&#8217;t appear on the automatic SIL system, even if they are up to ML2.0 in size. This suggest that there origin is from magma movements, not tectonics one (tectonics earthquakes also happen there).<\/p>\n<p>So far nothing suggest that a eruption is immanent. But that can change without any warning. As Gr\u00edmsfjall volcano is known to start a eruption with no warning at all.<\/p>\n<p><a href=\"http:\/\/icelandgeology.net\/wp-content\/uploads\/2011\/03\/grf.30.mars_.2011.gif\"><img loading=\"lazy\" decoding=\"async\" src=\"http:\/\/icelandgeology.net\/wp-content\/uploads\/2011\/03\/grf.30.mars_.2011-300x225.gif\" alt=\"\" title=\"grf.30.mars.2011\" width=\"300\" height=\"225\" class=\"aligncenter size-medium wp-image-721\" srcset=\"https:\/\/icelandgeology.net\/wp-content\/uploads\/2011\/03\/grf.30.mars_.2011-300x225.gif 300w, https:\/\/icelandgeology.net\/wp-content\/uploads\/2011\/03\/grf.30.mars_.2011.gif 640w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><\/a><br \/>\nHarmonic tremor levels in Gr\u00edmsfjall volcano on 30th March 2011.
