This two earthquakes did happen in Grímsfjall volcano today. There signature clearly shows that they are created by magma breaking the crust. The background noise (SIL tremor plot) in Grímsfjall volcano also appears to have changed following this two earthquakes. I am not sure why that it. But this two earthquakes might be a pre-sequence to a eruption in Grímsfjall volcano. But it is hard to be sure on that at this moment. But I am sure that it is getting shorter to a eruption in Grímsfjall volcano.
