Seismic activity at Bárðarbunga persists

18.8.2014

The intense seismic activity that started on 16 of August at Bárðarbunga persists. Very strong indications of ongoing magma movement, in connection with dyke intrusion, is corroborated by GPS measurements. There are currently two swarms: one to the E of Bárðarbunga caldera and one at the edge of Dyngjujökull just E of Kistufell. At 2.37 am on the 18th a strong earthquake (M4) was located in the Kistufell swarm.

This is the strongest earthquake measured in the region since 1996. As evidence of magma movement shallower than 10 km implies increased potential of a volcanic eruption, the Bárðarbunga aviation color code has been changed to orange. Presently there are no signs of eruption, but it cannot be excluded that the current activity will result in an explosive subglacial eruption, leading to an outburst flood (jökulhlaup) and ash emission. The situation is monitored closely.

Visitors to Iceland have been warned to monitor earthquake activity as the Foreign Office issues an alert. The National Police Commissioner in Iceland has declared a Civil Protection Uncertainty phase due to increased activity in the Brðabunga volcano in Vatnajokull glacier in the South East of Iceland. The FO said several hundred minor earthquakes have been detected east of Brðarbunga and around Kistufell. Visitors are advised to monitor Icelandic Met Office reports and follow the advice of the Icelandic emergency services. Up to date information

Seismic activity under Bárðarbunga vulcano and Kistufell north west of Vatnajökull. This is going to be interesting….
Most of the time in the past it caused “only” glacier floating an no big eruption because the ice above is 700 m thick.
We keep on watching Icelandic Meteorogical office website as shown above.
