In its most general sense, an earthquake is any seismic event—whether natural or caused by humans—that generates seismic waves. Earthquakes are caused mostly by the rupture of geological faults but also by other events such as volcanic activity, landslides, mine blasts, fracking and nuclear tests.

All of these activities can pose a hazard to humans. Earthquakes, hot springs, fumaroles, mud pots and geysers often accompany volcanic activity. Volcanic gases can reach the stratosphere, where they form sulfuric acid aerosols that can reflect solar radiation and lower surface temperatures significantly.
A volcano tectonic earthquake or volcano earthquake is caused by the movement of magma beneath the surface of the Earth. The movement results in pressure changes where the rock around the magma has a change in stress.
Volcanic eruptions and earthquakes were generally linked in these systems to the existence of great open caverns under the Earth where inflammable vapours could accumulate until they were ignited. According to Thomas Burnet, much of the Earth itself was inflammable, with pitch, coal and brimstone all ready to burn.
The Ring of Fire contains between 750 and 915 active or dormant volcanoes, around two-thirds of the world total. [3] [4] The exact number of volcanoes within the Ring of Fire depends on which regions are included. About 90% of the world's earthquakes, [5] including most of its largest, [6] [7] occur within the belt.
Volcano tectonics is a scientific field that uses the techniques and methods of structural geology, tectonics, and physics to analyse and interpret physical processes and the associated deformation in volcanic areas, at any scale.
