Months of Geologic Unrest Signaled Reawakening of Icelandic Volcano
*Monitoring volcanoes helps researchers understand the processes that drive them to erupt*
Months of volcanic restlessness preceded the eruptions this spring of Icelandic volcano Eyjafjallajökull, providing insight into what roused it from its centuries of slumber.
An international team of researchers analyzed geophysical changes in the long-dormant volcano leading up to its eruptions in March and April 2010. In a study published in the Nov. 18 issue of the journal Nature, the scientists suggest that magma flowing beneath the volcano may have triggered its reawakening. (more…)
