Eyjafjallajökull Eruption – ALI-EO1 Satellite Image

Increased seismicity reported at Eyjafjallajökull

More magma pumping from the volcano’s depth GPS-monitoring indicates inflation

Magma Intrusion – 05 May 2010 13:40

Icelandic Met Office (IMO) has detected increased seismic activity beneath Eyjafjallajökull starting Monday 3 May. “Precise locations of the earthquakes show that their source is at first very deep, at about 23 km depth, but then migrates upwards. This strongly indicates that “new” magma is intruding into the magma conduit and pushing on the over-lying magma, causing a difference in pressure at the surface. It is therefore anticipated that the eruption will continue at full force in the next days.”

Plume Height

IMO’s weather radar reported the plume height reaching to a height of about 6.5km a.s.l.

Lava Flow

Lava is flowing in a northerly direction and spreading at 500 m a.s.l., IMO said. “The lava tongue is about 200 m wide and lava channels that join at the tongue are about 30-60 m wide. The lava channels gets wider every day.”

GPS deformatio

IMO reported significant horizontal movement at GPS stations mounted around
Eyjafjallajökull in the last 2 days.
