Volcano monitoring data plots are temporarily unavailable on the USGS website due to a server malfunction. USGS staff are working on resolving the issue, but it may be several days before it is resolved. Internally, volcano monitoring data is accessible and USGS staff are able to monitor volcanic activity. We apologize for this temporary outage and hope to have it resolved soon.

The beginning of a new year is often a time for reflection about the highlights of the previous one. Seismologists reflect on large or impactful earthquakes, volcanologists on the highest ash plumes or lava fountains… but those of us at CalVO are marveling at just how uneventful 2025 was, at least as far as earthquakes near our volcanoes are concerned.

From Maine’s Acadia National Park to the wilds of Australia, geological conditions exist that slow the effects of climate change on the local ecology and inhabitants. How these “climate refugia” remain relatively protected from climate change impacts over time, and how they might help local plant and animal species survive, is a focus of Northeast CASC Research Ecologist, Toni Lyn Morelli.

Although the Yellowstone hotspot burned a swath of volcanic chaos across southern Idaho during the past 17 million years, it was an earlier period of volcanism, unrelated to Yellowstone, that shaped the geology of central Idaho.

Today marks one year since a unique episodic lava fountaining eruption began at Kīlauea’s summit on December 23, 2024—a style of activity not seen in nearly 40 years! Over the past 12 months, Halemaʻumaʻu crater has hosted more than 35 eruptive episodes, each lasting from a few hours to more than a week, separated by quiet pauses.

Your wait is over, ASTER users.

For years, you have patiently ordered ASTER (Advanced Spaceborne Thermal Emission and Reflection Radiometer) granules or images and waited for them to be processed before you could use them in your projects.

How does getting them immediately sound instead?

On December 23, 2024, a unique eruption began in Kīlauea’s Halemaʻumaʻu crater, with a style of activity not seen for nearly 40 years. The eruption, characterized by high lava-fountaining episodes, has continued for nearly a year. Hawaiʻi Volcanoes National Park visitors see remarkable views, but the latest episode reminds us how quickly hazards associated with this dynamic activity can change.

Beneath the surface of the ocean, vast layers of planktonic life are constantly on the move—rising, sinking, spreading, and regrouping in response to light, predators, currents, and storms. This epic choreography is sometimes called the largest mass migration on earth, and it happens every day, out of our view.

Red spruce forests, once widespread across the central and southern Appalachians, now persist only in scattered fragments on mountaintops. Researchers are partnering with local community groups to restore the spruce forest’s structure, creating resilient habitat for wildlife, while also protecting clean water, carbon storage, and outdoor recreation in the Central Appalachians.
