- W42896202 abstract "This chapter discusses a group of volcano-tectonic earthquakes that includes the earthquakes generated by stresses, which arise during magma migration in the Earth's crust. These earthquakes may be caused by shear or tensile fracturing during magma movement from depth to the Earth's surface through conduits and dykes. Volcano-tectonic earthquakes occur within and around the volcanic edifice and reflect the interaction of two general geological processes: the magma migration to the Earth's surface and the crustal tectonic activity. Magma is formed in mantle in two principal ways: the first way involves simple decompression of hot, solid mantle material, whereas the second involves lowering the melting temperature of the mantle material by the addition of volatiles. The location of the magma generation constrains its physical properties and constitution. Volcanoes normally occur within rift (or graben) type structures along long-lived faults. A graben is often formed above intruding dykes in volcanic rift zones because a dyke creates two zones of maximum tensional strain at the surface, parallel to the dyke axis. The high-frequency waveform of volcano-tectonic earthquake is characterized by clear arrivals of P- and S-waves. Both spectra have the dominant frequencies between 5 and 20 Hz, but the spectrum of P-wave is of higher frequency comparing with the spectrum of S-wave. The complete seismic moment tensor of an earthquake source may be described as a sum of its isotropic and deviatoric parts. The source of volcano-tectonic earthquakes, produced by movement along tectonic fractures, may be represented by its deviatoric part, which is responsible for the production of fracture." @default.
