Latest Volcanic ash Stories
While piloting a commercial transatlantic flight last year, Captain Klaus Sievers and his crew got a whiff of an unusual odor
Exposure to volcanic ash can increase respiratory symptoms such as an extreme cough, or phlegm.
In addition to being fairly unpredictable, volcanoes can eject a wide range of material, from mile-high plums of black ash to a deadly hail of fist-sized pumice.
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.
Mexico's Popocatepetl Volcano has re-awakened and has been emitting gas and ash. NOAA's GOES-13 satellite has been viewing the ash cloud, and it was documented in a short new video released by NASA's GOES Project on Friday.
The Popocatepetl volcano located outside of Mexico City has started spewing ash and fragments of glowing, molten rock thousands of feet down its slopes, forcing officials at one of the world's largest cities to increase the volcano's alert level.
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...
