A strong and dangerous earthquake with magnitude 5.9 hit 82 km SE of Dar es Salaam, Tanzania, beneath the Indian Ocean on August 12. Depth estimates are around 10 km as people in Dar es Salaam, Zanzibar Island, and other nearby coastal areas said to have felt moderate to strong tremors.
People near the epicentre of the quake, felt two waves – one was around 8 to 10 seconds of vibration while a second one was a long shock. Within half an hour there were 200 reports of the incidents while no reports of major damage or injuries have been reported so far.
It must be noted that as the country is far from plate boundaries and major faults, not many earthquakes of such size have occurred in recent history in this region. Seismic activity in east Africa is mostly because of the Eastern African Rift further to the east.
