Prediction of volcanic activity, and volcanic eruption forecasting, is an interdisciplinary monitoring and research effort to predict the time and severity of a volcano's eruption. Of particular importance is the prediction of hazardous eruptions that could lead to catastrophic loss of life, property, and disruption of human activities.
In Volcano-Tectonics, like in solid-earth geophysics in general, the main physical theories used are those that derive from continuum mechanics. For solid-earth sciences, these are mainly solid mechanics, including rock mechanics, fracture mechanics and general tectonophysics , and fluid mechanics , including fluid transport in rock fractures.
SeisMac is a free tool for recent Macintosh laptop computers that implements a real-time three-axis seismograph. The Development Of Very-Broad-Band Seismography: Quanterra And The Iris Collaboration Archived 2016-08-10 at the Wayback Machine discusses the history of development of the primary technology in global earthquake research.
Geochemists often use mass spectrometry and electron microprobe analysis to understand the pre-eruption history of volcanic rocks and how fast eruptions occur. Volcano geophysicist (or volcano seismologist) Planetary volcanologist - someone who studies volcanic processes on other planetary bodies.
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.
Certain constituents of volcanic gases may show very early signs of changing conditions at depth, making them a powerful tool to predict imminent unrest. Used in conjunction with monitoring data on seismicity and deformation, correlative monitoring gains great efficiency. Volcanic gas monitoring is a standard tool of any volcano observatory ...

Traditionally prospecting relied on direct observation of mineralization in rock outcrops or in sediments. Modern prospecting also includes the use of geologic, geophysical, and geochemical tools to search for anomalies which can narrow the search area. Once an anomaly has been identified and interpreted to be a potential prospect direct ...
