Lava in Hawaii, seismic shaking in Alaska and underwater rumblings near Oregon. Scientists say it’s not the end of the world, but it’s definitely worth watching.

Recent volcanic activity across the Pacific Ring of Fire has raised alarms among scientists and volcanologists, with several volcanoes experiencing heightened eruptions and seismic tremors. The Ring of Fire,

The United States Geological Survey (USGS) shows lava fountains shooting up high in the latest episode of an ongoing eruption of Kilauea volcano inside Hawaii Volcanoes National Park on Wednesday, June 11,

Hawaiian Volcano Observatory field engineers on July 10, 2025, visited monitoring stations downwind of the Kīlauea summit eruptive vents. They wore snowshoes, as the large footprint keeps the field engineers walking on top of the frothy pumice everywhere instead of sinking through it. (Photo Courtesy: US Geological Survey/M.Warren)

Volcanoes are rumbling as scientists monitor earthquakes at Washington's Mount Rainier and Alaska's Iliamna volcano.

Essentially, gas pistoning is a shallow, degassing-driven rise and fall of a lava surface. Often these pistons occur in narrow conduits — although they can happen in larger lava lakes and even in lava channels — and in bunches, as part of a series.
