Two dimensional finite difference simulation of magnetotelluric and magnetic variation soundings when the source field is considered

Abstract

We describe a two dimensional finite difference algorithm for the simulation of magnetotelluric (MT) and magnetic variation (MV) soundings. The algorithm was developed in order to compare apparent resistivity studies performed with these two methods. A source field with a finite geometry is considered. We illustrate an application of our algorithm through a simulation of this kind of soundings in Iceland.
