Eyjafjallajökull eruption

Heard and not seen


As said earlier, the eruption in Eyjafjallajökull has apparently entered a new phase with less interaction of magma with ice and melt water.

It seems that the ice cauldrons over the eruption site have coalesced to form a larger cauldron. In spite of magma splatters, no lava flow has been detected yet.

Heavy sound blasts have been heard and found near Eyjafjallajökull, especially south and east of the mountain. The viscosity of the magma from Eyjafjallajökull is higher than on Fimmvörðuháls and this enhances the explosive sound effect which can be heard over long distances.

An update on events and prospects, including ash forecasts as well as earlier information, can be found through links in red at IMO's front page. See also "Forecaster's remark" (to the right).
