Volcanic field

 ( Volcanoes ) 

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

Description Alexander von Humboldt observed in 1823 that geologically young volcanoes are not distributed uniformly across the Earth's surface, but tend to be clustered into specific regions. Young volcanoes are rarely found within , but are characteristic of subduction zones, , or in ocean basins. Intraplate volcanoes are clustered along hotspot traces.

Within regions of volcanic activity, volcanic fields are clusters of volcanoes that share a common magma source. Unlike a large volcano with satellite or subsidiary vents, a volcanic field's vents have their own source of magma, possibly of different compositions (such as basalt and rhyolite), and these vents may span an area of thousands of square miles. are particularly prone to cluster into volcanic fields, which are typically in diameter and consist of several tens to several hundred individual cones. The unusually large Trans-Mexican Volcanic Belt has nearly 1000 cones covering an area of .Schmincke 2003, p.100
