Iceland in the Central Northern Atlantic : hotspot, sea currents and climate change (Plouzané, France, 11/05/2010–14/05/2010)

Résumé

We deployed a temporary local seismic network in the North Tanzanian Divergence (NTD) for 6 months in 2007 (35 stations, SEISMOTANZ'07 experiment). The region is characterized by major changes in the magmatic/tectonic nature of the rift, at the place where the eastern branch of the East African Rift enters the Tanzanian craton. More than 200 earthquakes were accurately located south of Lake Manyara.
