It is associated with explosive interaction between magma and groundwater, a process that produced a broad maar and surrounding deposits on the...

Ubehebe Crater is a large volcanic maar located in the northern part of Death Valley National Park, California. It was formed by a phreatomagmatic explosion, in which rising magma encountered groundwater and produced a violent steam eruption. The crater measures roughly half a mile across and over 7...

Hole-in-the-Ground is a large Pleistocene-era maar volcano located in Lake County, Oregon. It was formed approximately 100,000 years ago by explosive phreatomagmatic eruptions, which occurred when rising magma interacted with groundwater.

Pulvermaar is a water-filled volcanic maar crater located in the Eifel region of Rhineland-Palatinate, Germany. Formed by volcanic explosions during the Pleistocene epoch, it is recognized as one of the deepest natural lakes in the state. The crater is surrounded by a distinct tuff ring, a geologica...

Isla Isabel is a volcanic tuff cone island located approximately 30 kilometers off the coast of Nayarit, Mexico. Designated as a national park and UNESCO biosphere reserve, it is sometimes called the 'Galápagos of Mexico' due to its diverse and abundant bird life. The island hosts large breeding col...

Hverfjall, also known as Hverfell, is a prominent tuff ring volcano located in northeastern Iceland, situated near the geothermal area of Lake Mývatn. The crater was formed approximately 2,500 years ago during a short but explosive volcanic eruption. It features a massive, circular crater measuring...

Lac Pavin is a deep crater lake located in the volcanic Auvergne region of central France. It was formed within a maar and tuff cone, representing one of the youngest volcanic formations in the country. The lake is scientifically notable for being meromictic, meaning its water layers do not mix, whi...

Lake Pupuke is a freshwater maar lake located on Auckland's North Shore in New Zealand. It was formed by explosive phreatomagmatic eruptions approximately 140,000 years ago, leaving behind a crater with low surrounding tuff rings. As one of the region's oldest volcanic features and a rare natural la...
