Mount Cameroon is the only active volcano of the Cameroon Volcanic Line and is located in an inhabited area. Consequently ground deformation monitoring is crucial. DinSAR has demonstrated its capability in various volcanic contexts. However Mount Cameroon is located close to the Equator and is under the influence of the Africa branch of the Inter-Convergence Tropical Zone (ICTZ), which plays a major role on the precipitable water vapor content in the atmosphere. This volcano also exhibits an elliptical shape and strong slope gradients. We discuss these factors that may hamper the use of radar images on Mount Cameroon.
