One of the most active volcanoes in the world sits just a few hundred miles off the U.S. West Coast, and some scientists believe it’s only a matter of time before it erupts again – maybe even before the end of 2025.

Experts are facing the wrath of the unpredictability of volcanic eruptions in an active site showcasing developments for years.

Poised some 300 miles off the coast of Oregon, one mile beneath the sea, yet rising 3,600 feet high, and spanning 1.2 miles across, one of the world’s most active volcanoes rests. It’s waiting, gurgling with seismic activity, preparing for a possible eruption sometime this year, according to scientists.
