Volcanic Super-Eruptions A Quicker Threat Than Previously Thought
2012-05-31 05:03:53

Lee Rannals for RedOrbit.com Volcanoes capable of super-eruptions that could be catastrophic for civilizations have short fuses, according to new research conducted at Vanderbilt University. Super-eruptions are more than 100 times the size of ordinary volcanic eruptions like Mount St. Helens. These types of eruptions spew out super-heated gas, ash and rock, and are capable of leveling entire continents. Researchers say that there is evidence of one super-eruption that took place in...

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. Now a new study, funded by the National Science Foundation, shows that the residents of that region are at risk from yet another potentially deadly natural phenomenon — major volcanic eruptions. Researchers from Oregon State University working with colleagues in Indonesia have documented six major...

Icelandic Volcano Ash Results Presented 2 Years After Eruption
2012-05-14 07:44:35

In May 2010, the ash cloud from the Icelandic volcano Eyjafjallajökull reached the Iberian Peninsula and brought airports to a halt all over Europe. At the time, scientists followed its paths using satellites, laser detectors, sun photometers and other instruments. Two years later they have now presented the results and models that will help to prevent the consequences of such natural phenomena. The eruption of the Eyjafjallajökull in the south of Iceland began on...

Satellite Provides Glimpse of One Week's Ash Activity From Mexico's Popocatepetl Volcano
2012-04-25 01:03:01

[ Watch the Video ] 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. "Most of the time, the prevailing westerly winds carry the debris (ash and smoke) far to the east in the mornings, while the daily rains bring down the ash before it can go far in the afternoon," said Dennis Chesters, of the NASA GOES Project at...

NASA Satellite Captures Video Of Mexico's Popocatepetl Volcanic Ash Cloud
2012-04-23 09:20:33

[ Watch the Video ] 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. NOAA's Geostationary Operational Environmental Satellite, GOES-13, captures visible and infrared images of weather over the eastern U.S. every 15 minutes, and spotted an ash and gas cloud streaming from Mexico's Popocatepetl Volcano over several...

Eruption Threat Level Increased At Volcano Near Mexican Capital
2012-04-21 05:40:16

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, BBC News and the Associated Press (AP) are reporting. The volcano, which is also commonly referred to as 'Popo,' has been expelling small amounts of ash on an almost daily basis since entering a round of eruptive activity back in 1994, the AP...

Mathematical methods help predict movement of oil and ash following environmental disasters When oil started gushing into the Gulf of Mexico in late April 2010, friends asked George Haller whether he was tracking its movement. That's because the McGill engineering professor has been working for years on ways to better understand patterns in the seemingly chaotic motion of oceans and air. Meanwhile, colleagues of Josefina Olascoaga in Miami were asking the geophysicist a similar question....

Satellite imagery is showing Alaska´s Cleveland Volcano spewing ash 15,000 feet into the air from uninhabited Chuginadak Island about 940 miles southwest of Anchorage, USA Today is reporting. “It´s not expected to cause a disruption to big international air carriers,” U.S. Geological Survey (USGS) scientist-in-charge John Power said, who went on to call the event a “small explosion”. Air carriers in the region are showing a bit more concern, “any...

Chilean Volcano Could Have Major Eruption In Hours Or Days
2011-10-28 11:41:59

A volcano in Chile has released three columns of steam and ash that combined into a cloud of over 3 miles high on Friday. Officials in the country evacuated 119 people from the Hudson Volcano area, as other nearby residents prepared to flee due to melting snow and ice becoming a flood issue. Chile's national geology service said that the steam and ash was coming from three craters, ranging from 650 feet to 1,600 feet wide.  The service said that a major eruption could occur...

Mexico Volcano Spitting Ash Half Mile Up
2011-08-31 11:06:39

  A volcano just south of Mexico City has started shooting ash out of its crater, reports the Associated Press. The Popocatepetl volcano spewed ash over a half mile into the sky four times on Tuesday, according to Mexico's national disaster prevention agency. The agency is asking people to stay at least 7 miles away from the crater of this volcano. The 17,886-foot volcano is about 40 miles south of Mexico City. --- Image Caption: Popocatepetl sends a plume of volcanic...

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...
