Iceland – Strong inflation suggests that Hekla volcano could be close to erupting

Significant rapid inflation at the famous volcano has been detected since early April and likely represents accumulation of rising magma underneath.

In mid March this year, an earthquake swarm, volcanic tremor and deformation were also believed to have been caused by rapid movement of magma under the volcano.

Since the volcano last erupted in March 2000 it is estimated that a significantly larger volume of magma has accumulated beneath the volcano, which means that a new eruption could be larger than the last one.
