A volcanic field is an area of Earth's crust that is prone to localized volcanic activity. The type and number of volcanoes required to be called a "field" is not well-defined. [1] Volcanic fields usually consist of clusters of up to 100 volcanoes such as cinder cones. Lava flows may also occur. They may occur as a monogenetic volcanic field or ...

The Coso volcanic field is located about 160 km (100 mi) northeast of Bakersfield, California, mainly within the boundary of the Naval Air Weapons Station, China Lake. It covers approximately 400 square kilometers (roughly 150 square miles) and is home to one of the largest producers of geothermal power in the U.S., with an output sufficient to ...

Northern Arizona's San Francisco Volcanic Field, which covers about 4,700 square kilometers (1,800 square miles), is an area of young volcanoes along the southern margin of the Colorado Plateau. Much of the field lies within Coconino and Kaibab National Forests.

2023年4月17日 · Volcanic fields are clusters of volcanoes or areas covered by volcanic rocks. Monogenetic volcanic fields consist mostly (or exclusively) of monogenetic volcanoes. These volcanoes (cinder cones, maars, tuff rings, and eruptive fissures) each experience one period of …

The town of Clearlake lies within the volcanic field, as does much of the 43,000-acre freshwater lake of its namesake. The Geysers steam field, which sits at the southwest margin of the volcanic region, is host to one of the world's most productive geothermal power plants, producing enough electricity for 850,000 homes.

2022年9月8日 · Volcanic fields mark the locations where magma is created under the planetary surface but cannot be extruded by the repeated use of a single conduit. Their lateral extension therefore is likely to delineate the dimensions of magma reservoirs at depth in a form that differs from the presence of isolated volcanic structures.

In volcano: Volcanic fields. Such areas have many geologically young cinder cones or other features that have not been individually identified as separate volcanoes. If the conduits through which magma ascends to the surface are scattered over a broad area, many short-lived volcanoes are formed rather than… Read More

This site is the homepage for the Global Volcanism Program at the Smithsonian Institution. It provides current volcanic activity notices, historical volcanic activity reports published by the Smithsonian since 1968, and basic data about over 1500 Holocene volcanoes.

2025年1月28日 · Lac de Gras kimberlite field, NWT: The sizes and shapes of typical shield, composite and cinder-cone volcanoes are compared on Figure \(\PageIndex{1}\), although, to be fair, Mauna Loa is the largest shield volcano on Earth. ... Most are comprised of fragments of mafic volcanic rock that were blasted out during a high-gas-pressure early phase ...

A volcanic field is a localized area of the earth's crust that is prone to local volcanic activity, and the resulting volcanic landforms. They are distinct from a volcanic group (volcanic complex), which are a collection of related volcanoes or volcanic landforms.
