Several weeks ago an earth tremor rattled the house of HOORC Library Assistant Joseph Matshelo, among other Maun residents. Now data about the earthquake has been sent to us by Dr. A. Cichowicz of the South African Council for Geoscience, through Professor T.S. McCarthy of the University of the Witwatersrand Okavango Research Group. The earthquake of August 16th (20:21 GMT) had a magnitude of 4.4, and the epicentre was located at 20.033 deg S and 23.184 deg E, which puts it on the Kunyere fault at the junction of the Marophe and the Kunyere rivers (see Google image). In HOORC's Library, you can find the Encyclopedia of earthquakes and volcanoes.
