Volcanic Mud Volcano
Volcano Terms and Definition


Super volcano - It's Under Yellowstone. And It's Overdue
A subterranean sea of molten lava that scientists are sure will burst through the Earth's crust it's just a question of when. And if the resulting super-volcanic eruption is anything like the last one on earth which plunged the world into darkness for six years, tipped us into the last Ice Age and reduced the human population to just 2,000 people we're in for one explosive ride

Mud volcano

A mud volcano is a small volcano-shaped cone of mud and clay, usually less than 1-2 m tall. These small mud volcanoes are built by a mixture of hot water and fine sediment (mud and clay) that either (1) pours gently from a vent in the ground like a fluid lava flow; or (2) is ejected into the air like a lava fountain by escaping volcanic gas and boiling water. The fine mud and clay typically originates from solid rock--volcanic gases and heat escaping from magma deep below turn groundwater into a hot acidic mixture that chemically changes the rock into mud- and clay-sized fragments.
