By Catherine Griffin | Science World Report Hekla looms over Iceland at 4,890 feet, its snow-capped top remaining white and stark against the blue sky. Now, this volcano may be getting a little more active. The National Commissioner of the Icelandic Police has declared an “uncertainty phase” for Hekla, which is the lowest level of warning for the restless volcano. [...]

By Dan Stevens | The Costarican Times It seems one of the tourist attractions and wonders in Costa Rica might be causing problems for both the people living around the volcano and destroying crops in the area due to the low level of the lake inside the Poas Volcano. The low level of the lake of the Poas [...]

By Annalee Newitz | io9 If you think asteroid strikes are scary, I’ve got some bad news for you. The most deadly events on Earth are caused by . . . Earth. New evidence suggests that underwater volcanoes may have wrecked our planet for thousands of years, and ultimately allowed dinosaurs to rule the world. We’ve [...]

Global Times Mount. Lokon in Tomohon of North Sulawesi in eastern parts of Indonesia erupted on Wednesday, spewing ash by up to 2,000 meters high and other volcanic materials, a volcanologist said. The eruption took place at 07:57 am local time Wednesday ( 2257 GMT Tuesday), unleashed volcanic materials on the slope of the volcano, [...]

Xinhua | CRI Colombian Caldas department emergency committee reported Saturday that the ‘Nevado del Ruiz’ volcano tends to currently increase its activity, as the alert level remains at yellow (III). Guido Echeverri Piedrahita, chairman of Caldas emergency committee, said the Volcanic and Seismological Observatory of Manizales only reported an increase of seismic activity in the [...]

eScience A team led by the University of Colorado Boulder looking for clues about why Earth did not warm as much as scientists expected between 2000 and 2010 now thinks the culprits are hiding in plain sight — dozens of volcanoes spewing sulfur dioxide. The study results essentially exonerate Asia, including India and China, two [...]

By George Dvorsky | io9 A scientist from the University of Utah has confirmed that two continent-sized “thermochemical piles” are slowly converging at the bottom of Earth’s mantle about 1,800 miles (2,900 km) beneath the Pacific Ocean. This process, says geologist Michael Thorne, could eventually lead to a cataclysmic eruption that could “cause very massive destruction [...]

By Johnny Kelly | Examiner Scientists are on alert and closely monitoring the increasing activity with an Alaskan volcano. The Anchorage Daily News reported Wednesday that the dome of the Cleveland Volcano was swelling, according to the Alaska Volcano Observatory. The observatory detected elevated surface temperatures Jan. 24 at Cleveland’s summit and satellite data obtained last week indicated that a growing [...]
Read More →Volcano location could be greenhouse-icehouse key
Science Codex A new Rice University-led study finds the real estate mantra “location, location, location” may also explain one of Earth’s enduring climate mysteries. The study suggests that Earth’s repeated flip-flopping between greenhouse and icehouse states over the past 500 million years may have been driven by the episodic flare-up of volcanoes at key locations [...]
Read More →Super volcano awakening in Italy?
By Natalya Kovalenko | VOR It looks like we may be in for an earth-shattering explosion. A dormant super volcano appears to be stirring under the Phlegraen Fields of Naples in Italy. Rising soil temperatures and surface deformation in the area have alarmed seismologists. In the distant past, volcanic super eruptions caused global climate change responsible [...]
