A series of Earth tremors, i.e., light earthquakes, was felt last week in the region between the restless volcanic mountain, Ol Doinyo Lengai, near the Ngorongoro conservation area, the Lake Manyara area, and Arusha.

Three years ago a series of tremors and quakes was experienced, and then the volcano had a minor eruption that was felt as far away as Kenya and even Kampala. The great African rift valley is a zone of intense seismic activity, and was born out of major quakes, according to scholars on the subject.

After a period of intermittent calm since the last major quake three years ago, the mountain, which has been spewing ashes and smoke since then, appears to be on the way to more activity, and seismologists and volcano experts are monitoring these events, trying to get some information to the general public in order to help them understand better what is presently going on again, in particular in view of the volcanic activity in Iceland.
