Unusual Seismic Reading at Bardarbunga

Barely 2 hours after a magnitude 5+ earthquake, there seems to be an unusual seismic reading at Bardarbunga. Can anyone explain this activity? This seems to coincide with a new feature showing up on aerial images. Check out the new opening just south and west of the main vent. Also, the continued subsidence has recently shifted direction. Is this all a sign that the system is getting ready to blow? […]

Magnitude 5.5 Quake Strikes Bardarbunga

Overnight a magnitude 5.5 quakes strikes Bardarbunga. This was one of the largest quakes in Iceland’s history. Comes on the back of 18 magnitude 3.0+ earthquakes on Saturday. Ground subsidence continues at the same rate as before and the lava flow continues at a similar rate. Since midnight there have been four quakes with a magnitude of 4.0 or higher around the volcano. The risk of a massive eruption seems to be getting higher. […]

Influences on the Bardarbunga Caldera

Bardarbunga GPS Data

As subsidence continues, I have to wonder what are the outside influences on the Bardarbunga caldera. How much additional downward pressure will come from ice and water sliding/running down into the new pit. I am not sure of the GPS unit’s proximity to the glacier. So I don’t know if the subsidence is close enough to allow ice or water to fill the giant pit. If it is close enough and water and ice is flowing inward, I would think the addition of the weight would just exacerbate the problem. Has something been set in motion here that cannot stop until the caldera fails? […]
