ARGV is located in EKONA, a village
situated 15 km from Buéa, the capital of the south-east province of Cameroon.
The group was founded in 1984 and was temporarily installed in Kumba. A
dedicated center was built in 1988 in Ekona and comprises a main building with
12 rooms for laboratory and office space and two lodging annexes with 3
bedrooms and a den each.
ARGV operates within the Institute for
Geological and Mining Research and is in charge of the Geophysical program for
the study and assessment of volcanological hazards.
SEISMOLOGY
Mount Cameroon is permanently monitored
with a network of 6 telemetered seismic stations. Signals are interpreted in
terms of magnitude and location of the earthquakes. Variations in the seismic
activity in space and time is used for forecasting the eruptive activity of the
volcano.
This network has temporarily been
extended with stations in Yaoundé and Foumbot. However, the stations could not
be serviced regularly and were returned to Ekona.
The seismic network is also used to
monitor regional and distant earthquakes.
GRAVIMETRY AND MAGNETISM
A gravimetric survey has been performed
in the Mount Cameroon volcanic zone. Compilation of this data with existing
surveys has allowed the preparation of a new gravimetric map for Cameroon.
Aeromagnetic surveys, however fragmentary, have revealed the existence of
unsuspected faults in the Foumban transcurrent zone.
Our studies are regularly published in specialised journals.
