Mount St. Helens is a part of a volcanic “ring of fire” so vast that it encircles the Pacific Ocean. Indeed, the other 12 major volcanoes in the Cascade Range of northern California, Oregon and Washington state lie within this geological phenomenon as well.
Is Mt St Helens part of the Ring of Fire?
Helens was known as the “Fujiyama of America.” Mount St. Helens, other active Cascade volcanoes, and those of Alaska comprise the North American segment of the circum-Pacific “Ring of Fire,” a notorious zone that produces frequent, often destructive, earthquake volcanic activity.

What if the Ring of Fire erupt right now?
It would also cause massive crop failures, leading to a global food shortage. And, as if things couldn’t get any worse, the toxic volcanic gases would create acid rain. The rain would make the oceans even more acidic, killing off coral reefs. Marine life would suffer an extinction event.
Why is it called Ring of Fire?
The Ring of Fire gets its name from all of the volcanoes that lie along this belt. Roughly 75 percent of the world’s volcanoes are located here, many underwater. This area is also a hub of seismic activity, or earthquakes. Ninety percent of earthquakes occur in this zone.

Is the Ring of Fire active now?
The Ring of Fire is a 25,000-mile strip in the Pacific Ocean made up of oceanic trenches, volcanic arcs, volcanic belts and plate movements.

Which volcano is most likely to erupt next?
Mauna Loa erupted most recently in 1984, and will erupt again in the future, posing significant risks to people living on the flanks of the volcano.
Is Yellowstone going to erupt?
Although another catastrophic eruption at Yellowstone is possible, scientists are not convinced that one will ever happen. The rhyolite magma chamber beneath Yellowstone is only 5-15% molten (the rest is solidified but still hot), so it is unclear if there is even enough magma beneath the caldera to feed an eruption.
