Seismo-electromagnetics

From Wikipedia, the free encyclopedia

Seismo-electromagnetics is the study of electromagnetic phenomena associated with seismic activity such as earthquakes and volcanos, and also the use of electromagnetic methods in seismology such as magnetotellurics. Links between the electromagnetic fields in the lithosphere and those in the atmosphere and ionosphere are also studied. Earthquake prediction is one of the aims of this area of research.

One site of current research is China, where a satellite launch is planned for 2014, to provide data from ionospheric phenomena for comparison with seismo-electromagnetic phenomena on the ground. Such a link is partially borne out in the current literature, with ionospheric phenomena already shown to precede seismic phenomena by a few hours to days. The network would potentially show whether such ionospheric phenomena are sourced from ground electrical phenomena.[1]
