Lake Averno (or Avernus) is a volcanic crater lake located in Italy's Phlegraean Fields, near Naples. The name derives from the Greek word 'aornos,' meaning 'without birds,' referring to the ancient belief that birds flying over the lake would die due to toxic volcanic fumes. In Roman mythology, it...

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...

Tower Hill is a volcanic complex in southwestern Victoria, Australia, consisting of a nested maar and tuff cone formed by explosive interaction between rising magma and groundwater. The inactive volcano lies within a broad crater occupied in part by wetlands and islands. The area is protected as Tow...

Kilbourne Hole is a volcanic maar in southern New Mexico, near the Mexican border and west of the Franklin Mountains. It formed through explosive interaction between rising magma and groundwater, producing a broad crater surrounded in places by deposits of fragmented volcanic material. The site is e...

Meerfelder Maar is the largest crater lake in Germany's Eifel region, notable for forming 80,000 years ago and containing paleoclimatic sediment records used in Quaternary geology.

Laguna de Atexcac is a maar crater lake located in the Serdán-Oriental basin in the state of Puebla, Mexico. It was formed by a phreatomagmatic explosion during the Pleistocene epoch, resulting in a distinct volcanic crater that subsequently filled with water. The lake is hydrologically closed and c...

Lake Alchichica is a saline, alkaline crater lake in Puebla, Mexico, occupying a maar surrounded by a volcanic tuff ring. It is distinguished by pale carbonate microbialites, commonly described as stromatolites, that form conspicuous structures along its shore and beneath the water. The lake also su...
