  Information - NH4.02 Electric, magnetic and electromagnetic phenomena related to earthquakes (co-listed in SM)

Event Information
Changes in the natural and/or artificial electric, magnetic and electromagnetic fields have been observed during the past few decades in relation with the earthquakes and with the tectonic processes. For example, disturbances in the ground electric currents, in the geomagnetic field, in the VLF-LF-MF radio signals as well the appearance of electromagnetic emissions in the frequency range from ULF to VHF has been revealed. Many observations suggest that these effects take place also prior the occurrence of the earthquakes, so that seismic precursors can be pointed out. In particular a clear lithosphere-atmosphere-ionosphere coupling appear. This symposium will focus on: (1) electric/magnetic signals and electromagnetic emissions related to seismo-tectonic activity; (2) disturbances in the electromagnetic waves propagation in the lithosphere, atmosphere and ionosphere related to the previous activity; (3) seismic precursors in the natural and/or artificial electric, magnetic and electromagnetic fields by ground and satellites observations; (4) modelling of the phenomena in the lithosphere and in the atmosphere-ionosphere, underlying mechanisms and lithosphere-atmosphere-ionosphere coupling; (5) laboratory experiments related to electric/magnetic signals and electromagnetic emissions from the rocks. Reviews of the past worldwide results as well presentations of future research plans are welcome.
