At the center of Republic Djibouti, an eroded rift called Asal is located where tectonic and magmatic activities can be observed at surface. Multiple studies were carried out with different exploration methods, such as structural, geophysical hydrogeological, to understand rifting processes characterize subsurface this rift. Among these deep geoelectrical structures need better defined magnetot...

Abstract Previous studies in Gondang Subdistricthave identified underground mud reservoirnear a rock intrusion, while another study near Subdistrict has deep fault structures. This will identify the distribution and characteristics of possible geological features area using magnetotelluric (MT) method to further describe relationship between related local geology. MT data measurements were cond...

Introduction. Electromagnetic (EM) sounding of the Moon and the Galilean satellites has yielded important insights on the interior structures of these bodies [e.g., 1-7]. These investigations measured magnetic fields only and required auxiliary information on the nature of the source fields. The magnetotelluric (MT) method, by measuring both magnetic and electric fields, can perform soundings f...

Three-dimensional magnetotelluric MT inversion is an emerging technique for offshore hydrocarbon exploration. We have developed a new approach to the 3D inversion of MT data, based on the integral equation method. The Tikhonov regularization and physical constraint have been used to obtain a stable and reasonable solution of the inverse problem. The method is implemented in a fully parallel com...

The paper presents a study, carried out in the context of TESEO project (Sistema di prospezione TDEM per l’ESplorazione gEOfisica dei pianeti), for the design of a TDEM (Time Domain Electromagnetic Method) system suitable for planetary subsurface exploration. The TDEM technique has been selected since it is based on the parameter of electrical conductivity, which is generally capable of discrim...

As one of the few deep-earth imaging techniques, magnetotellurics provides information on both the structure and physical state of the crust and upper mantle. Magnetotellurics is sensitive to electrical conductivity, which varies within the earth by many orders of magnitude and is modified by a range of earth processes. As with all geophysical techniques, magnetotellurics has a non-unique inver...
