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.

Some have called it as minor erruption (such as United Press International), but Mount Asama, one of Japan's most active volcanos, spewed ash and smoke up to 2000 metres into the air in an eruption early today.

BBC writes that "Residents living within a 4km radius of the mountain have been urged to be cautious.

Volcanoes cool the tropics

Climate researchers have shown that big volcanic eruptions over the past 450 years have temporarily cooled weather in the tropics—but suggest that such effects may have been masked in the 20th century by rising global temperatures.

Classic experiments give new insight on life's origin

The building blocks of life may have emerged in volcanic eruptions on the early Earth, according to a new analysis of classic experiments performed more than fifty years ago. Using modern techniques to examine samples from the original experiments, researchers discovered previously undetectable organic compounds.

Colombian authorities are evacuating thousands of people after a volcanic eruption about 240 kilometers southwest of the capital of Bogota.

Colossal blasts from ancient volcanoes

When Mt. Pinatubo erupted in the Philippines, in June of 1991, it blasted enough gas and dust into the air to block some of the sunlight in the atmosphere, causing the Earth’s global climate to cool for a few years.

Dinosaur Deaths Outsourced to India?

harminka — Tue, 30 Oct 2007 10:56:13 -0500

A series of monumental volcanic eruptions in India may have killed the dinosaurs 65 million years ago, not a meteor impact in the Gulf of Mexico. The eruptions, which created the gigantic Deccan Traps lava beds of India, are now the prime suspect in the most famous and persistent paleontological murder mystery, say scientists who have conducted a slew of new investigations honing down eruption timing.

Volcano rocks Yemen’s island in Red Sea

Dinka — Mon, 01 Oct 2007 11:04:06 -0500

A volcanic explosion rocked a tiny Yemeni island in the Red Sea, spewing lava and ash hundreds of feet into the air and forcing Yemeni authorities to evacuate a military base. NATO and Yemeni ships Monday were searching for eight missing soldiers.

Challenging earthquake theory behind Indonesian mud volcano
