Villagers in northern Namibia were shaken from sleep early Thursday by a moderate earthquake that happened shortly after 4 a.m., the second such quake to strike in southern Africa in a 24-hour period.

The epicenter was located about 64 kilometers to the northwest of Khorixas, according to the United States Geological Survey (USGS). Khorixas is a community of some 13,500 people in the Kunene region, a remote and mountainous area near important tourism and geology sites.

There were no immediate reports of damage or injuries.

People living in Khorixas, Anker and Fransfontein told The Namibian they felt the quake, but it occurred in a region with known seismic activity and thus did not surprise most of them.

Thursday’s quake occurred in the Kaoko orogenic belt, which runs northwest along the Namibian coast. Quakes there, while infrequent, are associated with the fault line. The Geological Survey of Namibia said it continued to analyze data from the quake.

It followed a 4.3-magnitude earthquake that affected Mozambique and Zimbabwe on Wednesday evening. That quake occurred near Chimanimani, about 145 kilometers inland from the coastal city of Beira, near a border area where Zimbabwean officials deployed new sensor instruments earlier this month to better record data in the seismically active region.

South African officials also have seen quake activity in recent weeks, including a 3.7-magnitude event on October 31 that was widely felt in the populated areas of Durban and Pietermaritzburg.
