Following a swarm of intense earthquakes, a new and apparently large explosive eruption started last night in Eritrea near the Ethiopian border, in an area which is the continuation of the spreading rift axis of the Red Sea.
USGS map of the Ethiopia-Eritrea earthquake swarm preceding the Dubbi (?) volcano eruption on 12 June 2012.
The eruption produced a large ash plume detected on satellite images. The plume is now stretching more than 1000 km westwards into Sudan. The vent location is still uncertain. The eruption is coming from either Afambo, Nabri or Dubbi volcanoes. The last historic eruption of these was from Dubbi volcano in 1861 and also produced a large ash plume.
The eruption was preceded by a strong earthquake swarm along the Ethiopia - Eritrea border near the mentioned volcanoes, which started on the afternoon of June 12. More than 12 earthquakes were reported with magnitudes ranging from 4.3 to 5.7 at depths between only 2 and 15 km, mostly around 10 km.
[update: it appears that not Dubbi, but neighboring Nabro volcano has erupted.]
