"There has been long-term geological, hydrological and vulcanological research by the Geology Department of the University of Tanzania and Sheffield University in the United Kingdom which is of particular interest."
"They continue to provide a rich field for vulcanological studies, as significant on-going geological processes in the development of landforms."
"Following the early work of von Humboldt, von Buch and Lyell, an enormous amount of vulcanological research has been done and is still carried out - into volcanic seismic activity, earthquakes, paleomagnetism and the collection of geo-chronological data."
