Earthquake Swarm at Esjufjoll Volcano Iceland
Another volcano in Iceland, Esjufjoll, is shaking the ground with probable magma movement beneath its 40 square mile caldera.
Dozens of earthquakes have rattled during the past 12 hours at Esjufjoll, between 1 and 3 km beneath the massive Vatnajokull ice sheet, the largest glacier in Europe, located at the southeast of Iceland.
The Vatnajokull glacier shares its ice with seven volcanoes, all associated with a ripping tear in the Earth’s crust where the Mid Atlantic Ridge forms a tectonic boundary.
Esjufjoll is most famous for causing a massive flood during 1927. Its last activity occurred during October 2002 when earthquake swarms indicated magma movement. Now, 8 years later during the same month, once again Esjufjoll is awakened.
Lets keep our eyes open…
Update: 28-Oct-2010, Just as fast as the swarm appeared, it has gone quiet. Perhaps building more pressure.
Update: 14-Nov-2010, After several weeks of quiet, Esjufjoll is quaking again, this time a mini swarm, some within minutes of each other, including a magnitude 3.1 at depth of 8.5 km.
