A new study provides "incontrovertible evidence" that the volcanic super-eruption of Toba on the island of Sumatra about 73,000 years ago deforested much of central India, some 3,000 miles from the epicenter, researchers report. http://www.physorg.com/news178210720.html Space & Earth Mon, 23 Nov 2009 14:59:10 EST news178210720 (PhysOrg.com) -- A team of chemists from the U.S. and France has found compelling evidence of a previously undocumented large volcanic eruption that occurred exactly 200 years ago, in 1809. http://www.physorg.com/news176049231.html Space & Earth Thu, 29 Oct 2009 15:35:09 EST news176049231 Worldwide, thousands of workers die every year from mining accidents, and instantaneous coal outbursts in underground mines are among the major killers. But although scientists have been investigating coal outbursts for more than 150 years, the precise mechanism is still unknown. http://www.physorg.com/news173595012.html Space & Earth Thu, 01 Oct 2009 06:40:01 EST news173595012 (PhysOrg.com) -- The effects of climate change are so uncertain and potentially long-lasting that policymakers should begin examining options that include geoengineering, an area that has so far been off-limits, according to a former Harvard researcher who is now a professor at the University of Calgary, Canada. http://www.physorg.com/news172943655.html Space & Earth Wed, 23 Sep 2009 17:10:02 EST news172943655 Scientists have found the "Rosetta Stone" of supervolcanoes, those giant pockmarks in the Earth's surface produced by rare and massive explosive eruptions that rank among nature's most violent events. The eruptions produce devastation on a regional scale -- and possibly trigger climatic and environmental effects at a global scale. http://www.physorg.com/news172766088.html Space & Earth Mon, 21 Sep 2009 15:36:23 EST news172766088 People living in the Seveso area of Italy, which was exposed to dioxin after an industrial accident in 1976, have experienced an increased risk of developing cancer. Researchers writing in BioMed Central's open access journal Environmental Health found an increased risk of breast cancer in women from the most exposed zone and an excess of lymphatic and hematopoietic tissue neoplasms in all but the least exposed zone. http://www.physorg.com/news172176738.html Medicine & Health Mon, 14 Sep 2009 20:10:01 EST news172176738 (PhysOrg.com) -- A team of geologists led by Cindy Ebinger of the University of Rochester have deployed 16 seismic sensors on one of the Galapagos Islands to study the processes of ocean island formation -- particularly those that occur right above mantle "hotspots." http://www.physorg.com/news171734872.html Space & Earth Wed, 09 Sep 2009 17:30:01 EST news171734872 When Alaska's Kasatochi Volcano erupted on Aug. 7, 2008, it virtually sterilized Kasatochi Island, covering the small Aleutian island with a layer of ash and other volcanic material several meters thick. The eruption also provided a rare research opportunity: the chance to see how an ecosystem develops from the very first species to colonize the island. http://www.physorg.com/news168793788.html Biology Thu, 06 Aug 2009 16:12:07 EST news168793788 (PhysOrg.com) -- The expanding spot discovered on Venus last month may not have garnered as much attention as the meteor impact with Jupiter, but its cause is certainly more puzzling. http://www.physorg.com/news168610535.html Space & Earth Tue, 04 Aug 2009 13:16:10 EST news168610535 (AP) -- Alaskans can put away their dust masks and spare air filters, for now, because Mount Redoubt seems to have cooled off since its last major eruption nearly three months ago. http://www.physorg.com/news165641574.html Space & Earth Wed, 01 Jul 2009 04:56:07 EST news165641574 A University of Colorado at Boulder team has uncovered an ancient and previously unknown Maya agricultural system -- a large manioc field intensively cultivated as a staple crop that was buried and exquisitely preserved under a blanket of ash by a volcanic eruption in present-day El Salvador 1,400 years ago. http://www.physorg.com/news164378297.html Other Sciences Tue, 16 Jun 2009 14:10:02 EST news164378297 An enormous eruption has found its way to Earth after travelling for many thousands of years across space. Studying this blast with ESA's XMM-Newton and Integral space observatories, astronomers have discovered a dead star belonging to a rare group: the magnetars. http://www.physorg.com/news164376716.html Space & Earth Tue, 16 Jun 2009 13:12:19 EST news164376716 For decades, geologists have been puzzled by the mechanisms that give rise to the kind of volcanoes that form the so-called `ring of fire` around the Pacific Ocean. These arc volcanoes, which account for about 10 to 25 percent of all volcanoes, are produced when one of the plates that make up Earth`s crust plunges beneath another plate, a process called subduction. http://www.physorg.com/news163684334.html Space & Earth Mon, 08 Jun 2009 12:54:21 EST news163684334 (AP) -- The summit of Hawaii's Kilauea volcano is glowing brightly as molten lava swirls 300 feet below its crater's floor, bubbling near the surface after years of spewing from the volcano's side. http://www.physorg.com/news163560445.html Space & Earth Sun, 07 Jun 2009 02:28:27 EST news163560445 (PhysOrg.com) -- Ancestors of tapirs and ancient cousins of rhinos living above the Arctic Circle 53 million years ago endured six months of darkness each year in a far milder climate than today that featured lush, swampy forests, according to a new study led by the University of Colorado at Boulder. http://www.physorg.com/news163081573.html Space & Earth Mon, 01 Jun 2009 13:26:49 EST news163081573 A previously unknown giant volcanic eruption that led to global mass extinction 260million years ago has been uncovered by scientists at the University of Leeds. http://www.physorg.com/news162738601.html Space & Earth Thu, 28 May 2009 14:13:04 EST news162738601 On Aug. 24, 79 A.D., Italy's Mount Vesuvius exploded, burying the Roman towns of Herculaneum and Pompeii under tons of super-heated ash, rock and debris in one of the most famous volcanic eruptions in history. http://www.physorg.com/news162397576.html Technology Sun, 24 May 2009 15:27:19 EST news162397576 (PhysOrg.com) -- A study into ash fallout from the biggest volcanic eruption in almost 20 years has shown that the impact of past eruptions is likely to have been significantly underestimated as so much of the evidence quickly disappears, Oxford University scientists report. http://www.physorg.com/news160836010.html Space & Earth Wed, 06 May 2009 13:41:25 EST news160836010 Nearly 2,000 years after wiping out Pompeii, Mount Vesuvius is among the most closely monitored volcanoes in the world, its every shudder recorded. http://www.physorg.com/news159599107.html Space & Earth Wed, 22 Apr 2009 06:06:19 EST news159599107 A volcanic eruption over the weekend has taken a toll on the wildlife of the ecologically-fragile Galapagos Islands, causing the deaths of numerous fish and various sea lions, said officials on Thursday. http://www.physorg.com/news159127819.html Biology Thu, 16 Apr 2009 19:10:39 EST news159127819 (PhysOrg.com) -- Researchers hit the jackpot in late March, when, for the first time, they began recording data on lightning in a volcanic eruption--right from the start of the eruption. http://www.physorg.com/news158430510.html Space & Earth Wed, 08 Apr 2009 17:29:13 EST news158430510 (PhysOrg.com) -- For the first time ever, a modern dance company has performed to music generated from seismic data, recorded from four volcanoes across three continents.

The lava composition indicates that a mantle plume -an upwelling of intense heat from near the core of the Earth -may be bubbling to life beneath the soil of the Democratic Republic of the Congo. The findings are presented in the current issue of the journal Chemical Geology. http://www.physorg.com/news156161448.html Space & Earth Fri, 13 Mar 2009 11:11:28 EST news156161448 Scientists have exploited crystals from lavas to unravel the records of volcanic eruptions.
