Maar craters are formed when magma encounters groundwater. The resultant venting to the surface excavates a bowl-shaped pit surrounded by a tuff ring that resembles a meteorite crater.

The term maar comes from a Franconian dialect for lake derived from the Latin “mare” (sea).
In the type locality—the Efiel Region of Germany— the craters extend below the water table and are occupied by lakes.
Maar craters range in size from a few hundred meters to several kilometers in diameter.
Their eruptive history consists of repeated venting over a period of weeks or months.
