Largest earthquake so far had the magnitude of 3,0. Other earthquakes have been smaller in magnitude. Most of the earthquakes that have been taking place are shallow, but all of them (at least that appear on my <a href=\"http:\/\/www.jonfr.com\/webicorders\/tremoren.htm\" target=\"_blank\">geophones<\/a>) are appearing to be <a href=\"http:\/\/kiska.giseis.alaska.edu\/input\/sanchez\/volcseis.html\" target=\"_blank\">long-period earthquakes<\/a>.

This is true, that is not the whole story in my view. Some of the earthquakes taking place in Tungnafellsj\u00f6kull volcano are due to tectonic adjustment of the crust (stress changes). What adds complexity to this image is the fact that magma is involved in Tungnafellsj\u00f6kull volcano, the problem that since there are no documented eruptions from Tungnafellsj\u00f6kull volcano, it&#8217;s impossible to know for sure what happens before an eruption in it. If the current influx of magma results in an eruption is difficult to say for sure, at the moment I don&#8217;t rule it out. It is my view that there is now more chance, rather than less of an eruption in Tungnafellsj\u00f6kull volcano.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>This is going to be short update on the activity in Tungnafellsj\u00f6kull volcano.
