Quick post today, but RUV is reporting that three small explosions occurred in the area just north of Vatnajökull. The nature of the explosions are unknown at this point, but from the rough translation of the article in Icelandic, they sound an awful lot like a phreatic explosion — that is, explosions driven by steam. If magma is directly involved, they would then become phreatomagmatic. In both cases, it could be a case where intruding basalt is interacting with saturated sediment at the edges of the Vatnajökull.
Scientists from the Icelandic Meteorological Office and University of Iceland took a number of flights over the region to observe these features that have come to two main preliminary conclusions: (1) these depressions are likely caused by melting of the ice from below and (2) these depressions lie along the water divide Jökulsá á Fjöllum River, which flows beneath 400-600 meters of ice.
ERUPTIONS blog, by Erik Klemetti, at wired.com has put together an informative and interactive group of posts that pit volcanoes of the world against each other (from countries in the actual 2014 FIFA World Cup) . Check out the posts and start voting for the 2014 Volcano World Cup winner!!
What is the Volcano World Cup? I’m going to take each of the participating countries in the real World Cup and have all of you vote on which are the most volcanically excellent. It will be set up exactly the same as the World Cup – group stage, round of 16, quarter-, semi- and finals – except it will be your votes that move nations forward.
