There are four volcano hot-spot regions in the U.S., besides Hawaii, where eruptions as big or bigger than Kilauea could happen.

Kilauea ripped open a new fissure on Monday, experts with the U.S. Geological Survey told CNN, and here's where something like that could happen elsewhere in the nation: Alaska, other places along the Pacific Coast, in Wyoming, and in the Rocky Mountains, The New York Times reported.

Most are less likely candidates, but don’t forget Mount St. Helens in Washington state where 40 tremblors were reported just in January.

1. Alaska: The Times said at least 50 volcanoes have been active there since 1760, attracting volcanologist and volcano watchers alike. Mount Cleveland, which is part of the Aleutian Islands, already has been tagged with a yellow alert by the Alaska Volcano Observatory of Alaska, where seismic and thermal activity and occasional ash clouds have been detected, per the Times.

The Alaska Maritime website said the entire chain of Aleutian Islands rides the northern arc of the so-called "Ring of Fire," – a line of inner friction where the Pacific plate of the earth's crust grinds slowly under the continental plates surrounding it. It is home not only to Mount Cleveland, but the Okmok Caldera and Kasatochi as well.

In July, a volcano erupted on Alaska's Aleutian Island chain, leading to an aviation warning.

2. Pacific Coast: The Times said volcanoes reside all along the coast from Long Valley Caldera in the Sierra Nevada, which last erupted 16,000 years ago, Mount Rainier near Seattle, which last erupted 1,000 years ago, and Lassner Peak near Redding, California, which erupted in 1917.

Mount St. Helens, near Portland, shocked many observers when it erupted in 1980, destroying forest in the tourists' destination for miles, the Times noted. Mount Hood and Mount Shasta have both erupted with the last few hundred years.

3. Wyoming: Yellowstone National Park, which sits mostly in Wyoming, is situated over a giant, active volcano, commonly referred to as a "supervolcano," The Washington Post reported. Researchers have said Yellowstone is capable of eruptions thousands of times more violent than the Mount St. Helens eruption of 1980 and ash from the explosion would rain over everywhere in the United States.

4. Rockies: Scientists warn that other volcanoes are sprinkled through the Mountain States, but their risk is so low that they are not monitored for now, the Times said.

Anywhere: The Times recounted the story of the volcano Paricutin, which rose stunningly from a Mexican cornfield starting in 1943. Springing seemingly out of nowhere, the volcano buried the village of Paricutín and grew to an elevation of 9,210 feet, according to Britannica.com.

The Times said Paricutin has helped researchers, who have followed the now-dormant volcano since its birth, to gain a better understanding of the science of volcano development.
