5.5 M earthquake hits Ethiopia


A potentially dangerous earthquake has hit on the border of Ethiopia and Eritrea, early this morning. The earthquake would have been very much felt in the city of Borama and villages nearby.

The USGS has its epicenter directly under Borama.

The huge difference in the estimates of GFZ and USGS show the deficiency of adequate seismological stations in this area of the world (similar to our PNG article).

There are no volcanoes in the immediate vicinity according to CATDAT, so this is most likely a tectonic earthquake in the East Africa rift zone.

A number of earthquakes have occurred in this region previously in 1930, 1951, 1961 and 1980.
