Latest Volcanic ash Stories
Researchers from The University of British Columbia and McGill University have simulated in the lab the process that can turn ordinary volcanic eruptions into so-called â€œsupervolcanoes.â€
Southern Chileâ€™s Chaiten volcano has blanketed the entire area in a white cloud of ash that has reached as far away as Argentina. Experts say the surprise eruption of the long dormant 3,280-foot Chaiten volcano, now in its seventh day, shows no signs of letting up and could go on for months.
A volcano located 80 miles south of Quito, Ecuador ejected molten rock, gas and ash on Wednesday.
QUITO, Ecuador (Reuters) - Rescuers on Friday searched for four people believed buried under rocks spewed by Ecuador's Tungurahua volcano, which forced thousands from their homes and killed one man in an eruption a day earlier.

By Jalil Hamid MOUNT MERAPI, Indonesia (Reuters) - In the shadow of Mount Merapi, a 30-year-old woman selling snacks to tourists visiting the rumbling Indonesian volcano says business has never been this bad.
Scientists are unearthing an Indonesian village buried nearly two centuries ago by the largest volcanic eruption in recorded history to learn how fast volcanic eruptions can turn deadly.
Ash from a steadily erupting volcano in south-central Alaska wafted slowly toward the southern Kenai Peninsula and grounded flights to and from Kodiak Island on Monday. Scientists reported that hot, gaseous pyroclastic flows were seen coursing down the volcano's slopes.
A volcano on an uninhabited island off the coast of Alaska erupted again on Tuesday, shooting ash miles (km) into the air, a scientist at the Alaska Volcano Observatory said.
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...
