Near Surface Fractures Evidence from Audio-Magnetotelluric (AMT) Investigation in Ayos-Nguelemendouka Area (Eastern Cameroon)


The current study deals with an interpretation of audio-magnetotelluric (AMT) data collected in the Ayos/Nguelemendouka area, using a Stratagem EH4 unit. The study’s objective is to provide a better understanding of the area’s subsurface structure. Thus, AMT soundings were realised through seven profiles NE30° oriented, each profile made up of four stations. Data modelling highlights a SW-NE tectonic unevenness which seems to correlate with the Centre Cameroon Shear Zone. Moreover, this interpretation put into evidence an uplift of the basement at Lamba 2, a tabular structure at depth and an absence of discontinuities beneath 300 mdepth.
