Medicine Lake Volcano Medicine Lake Volcano Medicine Lake Volcano is a large shield volcano in northeastern California about northeast of Mount Shasta. The volcano is located in a zone of east-west crustal extension east of the main axis of the Cascade Volcanic Arc and the Cascade Range. The thick shield is from east to west and from north to south, and covers more than . The underlying rock has downwarped by under the center of the volcano. The volcano is primarily composed of basalt and basaltic andesite lava flows, and has a caldera at the center. The Medicine Lake shield rises about above
Volcano tectonics understood within the framework of a reasonable model or theory of volcano behaviour. Quantitative and testable models must, in the end, be related to some physical theories and thus to physics. 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. Volcano tectonics Volcano tectonics is a scientific field that uses the techniques and methods of structural geology, tectonics, and physics to analyse and interpret
