On December 23, 2024, eruptive activity at Kīlauea’s summit began again with the first in what has become 20 discrete lava fountaining episodes. Many episodes have had dual fountains—two erupting at the same time—a rare occurrence at Kīlauea and worldwide. The most recent episode 20 concluded at 9:28 p.m. H.S.T. on May 6, 2025.

Episode 20 of the ongoing Halemaʻumaʻu eruption ended after four and a half hours of lava fountaining during the evening of May 6. USGS Hawaiiian Volcano Observatory geologists visited the eruption site on May 7, during the ongoing pause. The rapid rebound of recorded summit tilt from deflation to inflation at the end of episode 20 suggests another episode is likely

In an era of high-resolution satellite imagery, drone mapping, and other remote-sensing techniques, collecting data on how coastlines change over time has never been easier. But what about utilizing coastal imagery from time periods that pre-date satellite and aerial surveys?

A new paper in Science of the Total Environment, co‑authored by researchers from several USGS Mission Areas and Centers, including the California Water Science Center, finds fungicides, herbicides, and insecticides at every sampling site across five Sacramento Valley wildlife refuges. Because levels stayed high even far from crops, scientists are probing what this means for pollinators.

Episode 20 of the ongoing eruption in Halemaʻumaʻu at the summit of Kīlauea was active for 4.5 hours the evening of Tuesday, May 6, 2025. Lava fountains reached heights of approximately 500 feet (150 meters). The Halema'uma'u eruption is currently paused and the rapid change in summit tilt from deflation to inflation following episode 20 suggests that another eruptive episode is possible.

Along the Pacific Northwest coast, scientists have long warned of a looming threat: a massive earthquake from the Cascadia Subduction Zone, capable of triggering tsunamis and devastating shaking. Now, new research highlights another, often-overlooked danger—the sudden sinking of the land itself and the longer-term threats posed by coastal flooding.
