Askja volcano (Iceland): earthquake swarm near caldera at shallow depth
Montag Nov 11, 2019 07:35 | VON: T
The ongoing earthquake swarm at the Askja caldera in IcelandAn swarm of earthquakes is occurring near the Askja caldera, in an area approx. 10 km ENE from the rim and at depths around 5 km.
More than 550 small quakes have been recorded during the past 5 days, but so far, most quakes have been tiny. The largest events were two shocks with magnitudes 3.2 and 3.4, felt by local residents.
The swarm is likely caused by an intrusion of magma into an underground fissure (dike), which could but not necessarily must (and most often does not) lead to an eruption.
