TWO earthquakes, instead of the one reported in the media
yesterday, shook the Erongo Region on Saturday, according to the
Directorate of Geological Survey.
The first earthquake, measuring 4.5 on the Richter Scale, took
place at 06h45, while a second one measuring 3.8 occurred at
15h20.
According to the National Seismological Network, both earthquakes'
epicentres were about 58 kilometres south of Khorixas.
Five seismic stations in Namibia, namely at Kamanjab, Windhoek,
Tsumeb, Gobabis and Ariamsvlei, picked up the tremors, while two
stations in Zimbabwe also recorded the events.
"Faults can be seen close to the epicentre. These faults are
responsible for the earthquake," the Geological Survey report
read.
According to the Incorporated Research Institutions for Seismology
(IRIS), an earthquake registering 4.2 on the Richter Scale struck
northern Algeria about an hour after the first quake at Khorixas.
According to people living near Khorixas and Uis, tremors are felt
about once every six months, although Saturday's was stronger than
usual.
The biggest earthquake to hit Namibia in recorded history was the
2009 quake which registered 5.6. Its epicentre was also near
Khorixas.
