Abstract: The South Western Tanzania (SWTZ) is found within the Western branch of the East African Rift Valley (EAR) system, one of the most seismically active regions in African continent (Mavonga, 2010, 2007). The SWTZ area was strongly shaken by the magnitude 6.8 earthquakes that occurred on December 5, 2005, along Lake Tanganyika, living communities dwelling close to the earthquake epicenter in fears (USGS, 2005). No seismic sensors were close enough to provide instrumental recordings of the event, but few citizens who experienced the strong ground shaking provided eyewitness report via online questionnaire system (Did You feel it?) operated by the US Geological Survey (USGS) for global earthquake predictive shaking maps.
