Strongest earthquakes in Bárðarbunga volcano since February 2015
Posted on October 27, 2017 by Jón Frímann
Yesterday (26-October-2017) and today (27-10-2017) two strongest earthquake took place in Báðarbunga volcano since end of the eruption in February 2015. The magnitudes of earthquakes so far are two Mw4.7, One magnitude Mw3,9 and one Mw3,2 earthquake. So far other earthquakes have been smaller in magnitude. No harmonic tremor has been detected so far, but given the location an eruption might start in other part of the caldera without warning even if the earthquake swarm activity is happening in the northern part of the Bárðarbunga volcano caldera.
At the moment no eruption has been detected. But this strong and increasing earthquake activity suggest that magma pressure inside Bárðarbunga volcano might be reaching critical point. If it has not reached critical point already. For the next 24 – 36 hours really bad weather is forecasted in Iceland. With wind gusts forecasted up to 45m/s in the highland and in northern Iceland. This bad weather is going to cause problems in detecting earthquakes in Bárðarbunga volcano and elsewhere.
