Changes in the ultra-low frequency wave field during the precursor phase to the Sichuan earthquake: DEMETER observations
Electromagnetic phenomena observed in association with increases in seismic activity have been studied for several decades. These phenomena are generated during the precursory phases of an earthquake as well as during the main event. Their occurrence during the precursory phases may be used in s...
