is the energy utilized for anything productive?
UNANSWERABLE
when was the last time crater lake volcano erupted Approximately 7,700 years ago. where is mount mazama? Oregon, United States describe in few words the geology of the mount? It is part of the Cascade Volcanic Arc that stretches from northern California to southern British Columbia. Mazama sits within a region of crustal extension marked by fault zones what are some of the potential hazards from it? Landslides could threaten visitors to the national park or researchers by creating tsunami-sized waves, also potentially damaging infrastructure surrounding the lake. are there any geothermal activities around it? Scientists from the United States Geological Survey think that sources for geothermal energy use exist at Mazama and Crater Lake.

Mount Mazama [SEP] Geothermal energy
Studies of heat flow and the water chemistry in Crater Lake and the alteration of rocks older than 120,000 years ago suggest that hydrothermal areas exist in the Mazama vicinity. Most springs show similar chemistry, from the weathering of volcanic glass and clinopyroxene. These features probably formed due to processes related to residual heat from the magma chamber that produced the climactic Mazama eruption 7,700 years ago. The lake shows convective mixing that cycles every three years as thermal fluid moves into the lake through its floor, creating thermal springs that formed silica spires with heights up to . As a result, the California Energy Company drilled two geothermal exploration wells: the MZI-11A with a depth of to the east of the national park barrier at the Scott Creek Drainage, and the MZII-1 with a depth of to the south of the same boundary and to the east of Annie Creek.
