EARTH: Kilauea eruptions could shift from mild to wild

Hawaii's Kilauea volcano is famously effusive: Low-viscosity lava has been oozing out of the main caldera and two active rift zones along the southern shore of the Big Island since 1983. But scientists suspect that Kilauea's eruptions haven't always been so mild. In the past 2,500 years, at least two cycles of explosive eruptions lasting several centuries each have rocked the island. The switch from effusive to explosive is likely to occur again, scientists say, but probably not anytime soon.

Devastation and Recovery at Mt. St. Helens

From NASA Earth Observatory - The 1980 eruption of Mt. St. Helens, which began with a series of small earthquakes in mid-March and peaked with a cataclysmic flank collapse, avalanche, and explosion on May 18, was not the largest nor longest-lasting eruption in the mountain’s recent history. But as the first eruption in the continental United States during the era of modern scientific observation, it was uniquely significant.

Massive Underwater Shield Volcano Rivals Biggest in Solar System

The summer blockbuster movie Pacific Rim told a fanciful tale of giant monsters rising from the deep in the middle of the Pacific Ocean. Now, scientists have confirmed that the northwest Pacific is home to a real-life giant of a different type: the largest single volcano yet documented on Earth - or is it?
