Geo Hazards

Tanzania is within a geohazards prone area because of the East African Rift valley system cutting across the country on the eastern and south western which are earthquake prone areas. The country boaders the Indian ocean on the eastern part which is prone to tsunamis.

The  main goal is to identify geohazards monitoring, assess, find mitigation measures and introduce public awareness. Monitoring of geo-hazards (earthquakes, volcanoes, tsunamis, land slides and naturally leaching materials) provides information necessary for setting up mitigation measures in order to prevent life and properties of the community.

GST undertakes surveys on selected geo-hazards prone areas, update existing information and publish the findings. Among the immediate strategic plans of GST for geohazards management include: 

  • Investigation of seismisity around more earthquake prone areas such as  Arusha, Dodoma, Mbeya and Rukwa regions and prepare reports. So far five seismic stations have been installed at Panda Hill (Mbeya Region), Kibaya (Arusha Region), Singida Municipality, Dodoma Municipality, Manyoni (Singida Region) and Kondoa (Dodoma Region) with the aim of monitoring seismic activities.
  • Mapping of land slides prone areas such as Kilimanjaro, Tanga and Arusha regions produced prepare reports.
  • Investigate the impact of soil/bedrock chemistry to the environment for Iringa, Singida and Arusha and prepare reports.
  • Strengthening seismological and gas emission detectors monitoring network systems in selected areas of the country. This is implemented by installation of seismic stations and gas emission detectors.
  • Establishing online linkage with Webpage of the USGS for monitoring of earthquakes and tsunamis
  • Sensitising the public on how to react and report geohazard events, by conducting seminars
