Several volcanoes in the Pacific Ring of Fire have shown increased activity, leading to close monitoring by experts. The US Geological Survey has identified four active volcanoes in the US, including the Great Sitkin Volcano in Alaska, which has been erupting lava steadily since 2021. In Hawaii, Kilauea has paused lava fountains but continues to build pressure, with elevated sulfur dioxide emissions indicating ongoing activity. Mount Rainier in Washington experienced a significant earthquake swarm, while the Axial Seamount off Oregon's coast is under observation for a possible eruption in 2025. None presently threaten nearby communities.
The Great Sitkin Volcano in Alaska has been steadily erupting lava into its summit crater for nearly four years, confirming a slow and non-explosive lava flow Southwest.
Kilauea in Hawaii has paused its lava fountains but continues to build pressure, with sulfur dioxide emissions remaining elevated between 1,200 and 1,500 tons per day.
Mount Rainier experienced its largest earthquake swarm in early July, with 334 quakes detected over two days, raising vigilance among volcanologists.
The coastal underwater Axial Seamount, located offshore Oregon, is being monitored closely, with researchers forecasting a potential eruption occurring in 2025.
