En muddervulkan er en vulkanformet forhøyning av leire og slam, vanligvis mindre enn 2 meter høy.
De bygges opp av en blanding av varmt vann og fine sedimenter, som kommer ut av åpningen på
slamhaugen. Leiren kommer fra fast fjell som har gjennomgått en kjemisk reaksjon, eftersom gasser
og hete fra magma langt under overflaten, forvandler grunnvannet til en syreblandning som reagerar
med fjellet.

In volcanic regions, mud volcanoes are usually small volcano-shaped cones of mud, usually less than
1-2 m tall as shown in this image. They are built as mud erupts from a vent, either as as a flowing
liquid or ejected into the air. The mud is formed as acid gases rise through the crust, react with
rock and turn it into clay. The mud is a mixture of clay and groundwater. The mud volcanoes erupt
following pressurization from geothermal steam and gases.
