Latest Volcanic ash Stories
Although less than two percent of the fossils on earth are preserved in volcanic rock, researchers from the University of Montpellier have identified a new one. They found the skull of a rhino that perished in a volcanic eruption 9.2 million years ago.
Clouds of volcanic ash from Anak Krakatau, or child of Krakatau, have become so prominent in recent days that Indonesian authorities have issued a warning for local residents and tourists.

A modern recurrence of an extraordinary type of volcanic eruption in Iceland could inject large quantities of hazardous gases into North Atlantic and European flight corridors, potentially for months at a time, a new study suggests.
Volcanoes capable of super-eruptions that could be catastrophic for civilizations have short fuses, according to new research conducted at Vanderbilt University.
The early April earthquake of magnitude 8.6 that shook Sumatra was a grim reminder of the devastating earthquakes and tsunami that killed tens of thousands of people in 2004 and 2005.
In May 2010, the ash cloud from the Icelandic volcano Eyjafjallajökull reached the Iberian Peninsula and brought airports to a halt all over Europe.
Satellites continue to provide a look at the ash and gas clouds being emitted from Mexico's Popocatepetl Volcano. NASA has animated imagery from NOAA's GOES-13 satellite to provide a week long look at the volcano's activity.
Volcanic ash is the term for very fine rock and mineral particles less than 2 mm in diameter that are ejected from a volcanic vent. Ash is created when solid rock shatters and magma separates into minute particles during explosive volcanic activity. The usually violent nature of an eruption involving steam (phreatic eruption) results in the magma and perhaps solid rock surrounding the vent, being torn into particles of silt to sand size. The plume that is often seen above an erupting volcano...
