| 'Eyjafjallajokull could incite an eruption of its larger neighbor, Katla, which hasn't erupted since 1918 and might be ready to rumble. In all three historically recorded eruptions of Eyjafjallajokull -- in 920, 1612 and 1821 -- Katla erupted soon thereafter. ' http://www.washingtonpost.com/wp-dyn/content/article/2010/04/21/AR2010042102100.html It is thought that Katla is the source of the Vedde Ash (more than 6 to 7 cubic kilometers (1.4 to 1.7 cu mi) of tephra dated to 10,600 years BP) found at a number of sites including Norway, Scotland and North Atlantic cores.    Iceland Seismic Stations Map: http://hraun.vedur.is/ja/oroi/      You can see both volcano glaciers here (Katla it the bigger one):  A very interesting blog about the current eruption (when you find the time): http://scienceblogs.com/eruptions/2010/03/increasing_signs_of_activity_a.php http://en.wikipedia.org/wiki/Volcanic_Explosivity_Index |
