Strong earthquakes are setting off a powerful volcanic eruption in Eritrea (based on satellite images)

Earthquake / Eruption summary : During the late afternoon and evening of June 12 2011, a series of moderate earthquakes struck the Afambo, Eritrea area. The moderate earthquakes were followed by 2 strong 5.7 earthquakes. Based on the earthquake pattern and the locations of the epicenter, volcano activity seemed imminent.

UPDATE 13/06 ? 00:47 UTC : From now on we will have to wait for local reports, pictures, video?s etc.
We are very eager to get a confirmation that nobody was hurt and that no damage was inflicted during the earthquake and/or eruption.
Many scientists will board airplanes to take a close look at the volcano, take samples, etc.

UPDATE 13/06 ? 00:15 UTC : This is a very recent Google earth picture (combined with satellite cloud image). The size of the cloud is 150 km on 50 km! (91 on 35 miles)...

USGS: Map of East Africa showing some of the historically active volcanoes(red triangles) and the Afar Triangle (shaded, center) -- a so-called triple junction (or triple point), where three plates are pulling away from one another: the Arabian Plate, and the two parts of the African Plate (the Nubian and the Somalian) splitting along the East African Rift Zone.
