HATARI project (HAzard in TAnzania RIft) is an inter-disciplinary project dedicated to the study of the geodynamical processes impact on environment, society and learning abilities. A temporary seismic network of 8 broadband stations have been deployed for a year between Arusha and Olduvai Gorges to study the seismic and volcanic hazard in Northern Tanzania. Four stations were deployed around Mount Meru to record potential micro seismicity, while 4 stations were deployed near Gelai, Ngorongoro, Longido and Mto Wa Mbu to characterise the local seismicity in this particular area of the North Tanzania Divergence.
