The ARGV is responsible for implementing a programme of geophysical and geochemicl studies, within the IRGM. This structure focuses on natural hazards, and structural, geodynamic, and geological prospection. Several projects have been established since 1982, that have mainly focused on the Cameroon Volcanic Line (CVL) and in particular, Mount Cameroon, the only active volcano on a chain which extends over 1,500 km. Activities are conducted in three laboratories: the Seismology Laboratory, the Laboratory of Applied Geophysics, and the Laboratory of Volcanology.
