The seismic scientific expedition involves remote sensing interpretation, seismic geological survey, seismic hazard survey, crustal deformation observation, artificial seismic detection, portable seismic array observation, gravity detection, geomagnetic survey, deep seismic reflection, geochemical observation, source rupture process and seismic tectonic mechanism, earthquake sequence research and so on. All of these will generate a large number of survey results, observation data and research results, which will become the important basic information for understanding the characteristics of the earthquake and the deep seismogenic environment in the source area.
