A moderately strong, 5.5-magnitude earthquake struck in Ethiopia on Sunday, according to the United States Geological Survey.

The temblor happened at 9:53 p.m. East Africa time about 28 miles north of Āwash, Ethiopia, data from the agency shows.

As seismologists review available data, they may revise the earthquake’s reported magnitude. Additional information collected about the earthquake may also prompt U.S.G.S. scientists to update the shake-severity map.
