All volcanoes in the Cascade Range of Oregon and Washington are at normal background activity levels. Current Volcano Alert Level: NORMAL Current Aviation Color Code: GREEN During the past week, small earthquakes were detected at Mount Rainier, Mount St. Helens, and Mount Hood. Field crews were at Mount St. Helens and Mount Rainier to finish installation of new monitoring stations. Last week, CVO staff installed five new stations along the White River, north of Mount Rainier in Washington state.

Kīlauea summit eruptive activity resumed just before 3:00 p.m. HST today, January 22, 2025. Small lava dome fountains in the north vent are feeding short lava flows in the southwest part of the caldera. Volcanic gas emissions are elevated compared to during the eruptive pause. This marks the beginning of the fifth episode of the eruption that began on December 23, 2024, in Hawaiʻi Volcanoes National Park.

$For this month's video update of the Yellowstone Volcano Observatory, we'd like to introduce you to a friend of ours. This friend has been monitoring changes of the ground surface in Yellowstone for decades and is so good that it can detect movement of just a few millimeters in magnitude (just a fraction of an inch). The friend? A continuous GPS station! There are dozens of continuous GPS stations throughout the Yellowstone region, and they show us that the ground in Yellowstone is always changi$

USGS Hawaiian Volcano Observatory geologists observed lava roiling in the north and south vents at the summit of Kīlauea on Friday, November 21. Shortly after, lava flowed onto Halemaʻumaʻu crater floor for the first time since episode 36 (November 9). That activity continued through the weekend, with 73 overflows total. Over the past 24 hours, Kīlauea summit deflated and the overflows stopped, causing the forecast window for episode 37 to be adjusted slightly later in time. Episode 37 could occ
