Volcano raises concerns of eruptions

The eruption of a Hawaii volcano in the Pacific “Ring of Fire” has experts warily eyeing volcanic peaks on America’s West Coast that are also part of the geologically active region.

The West Coast is home to an 800-mile chain of 13 volcanoes , from Washington state’s Mount Baker to California’s Lassen Peak. They include Mount St. Helens, whose spectacular 1980 eruption in the Pacific Northwest killed dozens of people and sent volcanic ash across the country, and massive Mount Rainier, which towers above the Seattle metro area.

“There’s lots of anxiety out there,” said Liz Westby, geologist at the U.S. Geological Survey Cascades Volcano Observatory in Vancouver, Washington, in the shadow of Mount St. Helens. “They see destruction, and people get nervous.”

Kilauea, on Hawaii’s Big Island, is threatening to blow its top in coming days or weeks after sputtering lava for a week, forcing about 2,000 people to evacuate, destroying two dozen homes and threatening a geothermal plant. Experts fear the volcano could hurl ash and boulders the size of refrigerators miles into the air.

Here are some key things to know:

What is the ring of fire?

Roughly 450 volcanoes make up this horseshoeshaped belt with Kilauea situated in the middle. The belt follows the coasts of South America, North America, eastern Asia, Australia and New Zealand. It’s known for frequent volcanic and seismic activity caused by the colliding of crustal plates.

America’s most dangerous volcanoes are all part of the Ring of Fire, and most are on the West Coast, according to the U.S. Geological Survey. Besides Kilauea, they include: Mount St. Helens and Mount Rainier in Washington; Mount Hood and South Sister in Oregon; and Mount Shasta and Lassen Volcanic Center in California.
