Assessment - 27 April 2010 22:40
Overall assessment: Plume elevations and magma discharge levels remain similar to the preceding four days of activity. Lava continues to flow north from the eruption site toward the head of the Gígjökull glacier. Despite light ash-fall occurring up to 45 km west of the eruption site, today's explosive activity and ash production represents a fraction of conditions during the height of the eruption (14?17 April). There are no measurable indications that the eruption is about to end.
Seismic tremor: Intensity comparable to the preceding four days of eruptive activity.Earthquakes: No locatable seismicity has been recorded today beneath Eyjafjallajökull.
GPS deformation: Horizontal displacement towards the centre of the volcano, in addition to vertical subsidence. These observations are consistent with deflation of a magma reservoir beneath Eyjafjallajökull.
Magma flow: No measurements possible today; however, the intensity of the eruption suggests that the discharge level is similar to the preceding four days (i.e. 20?40 tonnes s?1).
Meltwater: Continuing discharge of water from Gígjökull due to ice-melt at the eruption site. Discharge at the old Markarfljót bridge, 18 km from Gígjökull, is estimated at ~100 m3 s?1, of which ~30 m3 s?1 is baseflow.
Other remarks: No measurable geophysical changes within the Katla volcano.
Based on: IMO seismic monitoring; IES-IMO GPS monitoring; IMO river gauges; information from local police; and aerial observations over the eruption site.
The above is based on status report issued collectively by IMO and the Institute of Earth Sciences at 19:00 this evening.
por cierto..
os presento al eyjafjalla:
Como veis.. esta poniendo mala cara....
