Lusi, the world’s largest and fastest growing mud volcano, had developed the mound-like shape of a volcano when this false-color image was acquired in October 2009, two and a half years after its birth.
This image from February 11, 2010, shows several mud volcanoes that rise from the desert landscape of southern Pakistan, along the coast of the Arabian Sea.
Using data acquired September 13, 2002, this 3-D visualization shows an old lahar (avalanche of volcanic mud) extending from Anyuyskiy Volcano in far eastern Russia.
“Stable landslide” sounds like a contradiction in terms, but there are indeed places on Earth where land has been creeping downhill slowly and harmlessly for as long as a century.
The paths of more than a dozen lahars radiate down the flanks of El Salvador’s Volcáan San Vicente in all directions following torrential rains in November 2009.
