Leirhnjúkur is an active geothermal area within Iceland’s Krafla caldera. It features numerous mudpots fueled by subsurface heat and volcanic activity. The site gained prominence due to its association with the 1975-1984 Krafla Fires, where lava continued to emit steam. Geologists and volcanologists...
The Hverarönd mud pots are a series of active geothermal features located in the Hverir geothermal area, adjacent to Námafjall mountain in northeastern Iceland. Situated within the high-temperature Krafla volcanic system, the pools consist of boiling, mineral-rich clay that bubbles to the surface th...
The Las Pailas Mud Pots are a cluster of active geothermal features located within Rincón de la Vieja National Park in Costa Rica. These boiling mud pots are formed by surface hydrothermal systems where sulfuric gases and steam from the underlying active volcano heat groundwater. The viscous mud con...
Bumpass Hell is a hydrothermal area located in Lassen Volcanic National Park in Northern California, renowned for its highly acidic mudpots and fumaroles. The geothermal site features boiling, muddy water pools that emit sulfurous gases, highlighting the volcanic activity beneath the surface. It is...
Dachnye Hot Springs are a collection of active mudpots located within the Mutnovsky caldera in Kamchatka, Russia. These springs feature unique geothermal activity including bubbling mudflows and steam vents. The area’s notable mineral composition and consistent temperatures make it an important site...
Seltún is a geothermal area within Krysuvik on Iceland’s Reykjanes Peninsula. It features active mudpots characterized by intense sulfur deposits. The site gained attention in 1999 and 2010 due to powerful hydrothermal bursts. Seltún is of interest to geologists, volcanologists, and anyone studying...
Davis-Schrimpf Mud Pots are carbon-dioxide-driven hydrothermal seeps near California's Salton Sea, notable for saline mud and gryphons up to about 2 m tall.
Las Hornillas Volcanic Activity Center is a geothermal site on Costa Rica's Miravalles volcano, notable for mud pots and the nearby ICE power project.
Devils Kitchen Mudpots lie in California's Lassen Volcanic National Park, within its second-largest hydrothermal area of springs and steam vents.
Sulphur Springs Mud Pots are acidic geothermal features in New Mexico's Valles Caldera, notable as rare western U.S. habitats for extremophile microbes.
