Katla early warning

As anyone who's ever studied the subject even superficially is aware, volcanoes and earthquakes or tremors go together like bread and butter. Large movements of magma down in the bowels of the Earth cause 'swarm' Earth tremors and quakes. At the moment of writing there are no such quakes reported from under the 10km wide Katla caldera in Iceland.

You can check this out here via the Earthquake map. The site text is in Icelandic, but the map is pretty clear. While there is a cluster of quakes accompanying the Eyjafjallajökull eruption, there are no reported indicators under Katla, or even its lava dome to the East side of its glacier, the most likely site for an eruption.

News on the eruption, and others via the USGS reporting web page is here.
