Description:
Recent earthquakes have provided and have renewed interest in question of the existence of electromagnetic
(EM) signals related to strong earthquakes. Latest observations (ULF-VLF) from ground and satellite based sensors
provide evidence for the existence of electrical and magnetic signals prior to some earthquakes. A further question
that is still widely debated in the science community is whether such signals precede and were connected with the
earthquakes. The main reason for this cautious assessment is a lack of understanding for the link between the
seismo-mechanical processes in the ground and the atmospheric/ionospheric and electromagnetic events. This
session will consider the causes, methodological approaches, and observations of EM phenomena related to
earthquake activity. Topics include: a) EM signals caused by stress changes in the Earth's crust; b) theory relating
tectonic stress changes to electrical, electro-chemical and thermodynamic processes; c) case studies, reanalysis
and new facts; d) ground, GPS and space-based methods for EM observation, validation and data mining and e)
modeling of EM phenomena in the lithosphere, atmosphere, and ionosphere. Contributions are solicited on all
potential EM earthquake related phenomena.
