Magnitude 5.3 Earthquake Hits Bárðarbunga

Seismic activity in the Bárðarbunga system and volcanic activity at the eruption site in Holuhraun is comparable to recent days, the Icelandic Met Office reported this morning. A magnitude 5.3 earthquake hit on the northern rim of the caldera at 08:36 am.

Changes in Groundwater May Signal Large Earthquake

The results of a new study on two large earthquakes in North Iceland in 2012 and 2013 indicate that changes in the chemical composition of groundwater in areas prone to earthquakes may be used to predict large earthquakes and to improve knowledge of processes in the earth’s crust.

Continued Seismic Activity at Bárðarbunga

Around ten earthquakes occurred in and around Bárðarbunga volcano between midnight and 7:30 this morning. The largest quake measured magnitude 3.9 and occurred shortly after 3:30 am, as reported on the website of the Icelandic Met Office.

Glacial River Retreats as Lava Flow Grows

A new branch of the lava flowing from the Holuhraun eruption is constricting glacial river Jökulsá á Fjöllum, which keeps retreating, as volcanologist Ármann Höskuldsson described from the scene. The new lava now covers an area measuring 50 square km.

Status Quo at Bárðarbunga and Holuhraun

The eruption activity in Holuhraun and seismic activity around Bárðarbunga volcano under Vatnajökull glacier remain stable, according to the latest scientific updates. The largest earthquake to hit Bárðarbunga since 7 pm yesterday was of magnitude 4.8.

Maps of Earthquakes each Day

The Icelandic Met Office has now issued a new feature to its website, showing the most recent earthquakes at Bárðarbunga on maps that are updated more or less continuously.

Lava Keeps Building up

The lava from the Holuhraun eruption flows at the same rate as yesterday, mostly around the center of the lava field, which is now around 37 square km (14.3 square miles).
