Precursory phenomena
WebPrecursory phenomena Variations in the physical and chemical parameters of a volcano system that indicate possible repeat eruptions. Some of these can only be detected by instruments, while others, such as for example more severe earthquakes, visible ground deformation, the appearance of the new fumaroles or the opening of fissures, can be … WebA growing array of precursory phenomena signal unrest preceding most eruptions. Technological advances and the expansion of monitoring infrastructure at some volcanoes over the past few decades allow quick detection and interpretation of signals of unrest days to months prior to an eruption (e.g., Ewert et al., 2005).

WebSeismo-electromagnetics are various electro-magnetic phenomena believed to be generated by tectonic forces acting on the earth's crust, and possibly associated with seismic activity such as earthquakes and volcanoes. Study of these has been prompted by the prospect they might be generated by the increased stress leading up to an earthquake, … Web(5) Regard Chinese Internet as precursory Sohu, make so narrow move, let a person be surprised really.
