A review on electrokinetically induced seismo-electrics, electro-seismics, and seismo-magnetics for Earth sciences
Résumé
The seismo-electromagnetic method (SEM) can be used for non-invasive subsurface exploration. It shows interesting results for detecting fluids such as water, oil, gas, CO_2 , or ice, and also help to better characterise the subsur-face in terms of porosity, permeability, and fractures. However , the challenge of this method is the low level of the induced signals. We first describe SEM's theoretical background , and the role of some key parameters. We then detail recent studies on SEM, through theoretical and numerical developments , and through field and laboratory observations, to show that this method can bring advantages compared to classical geophysical methods.
