ANIMATED GIF: At Kīlauea summit, the KWcam webcam recorded several small color changes along the lake margin following rockfalls which impacted the lake surface. These rockfalls immediately followed a M3.1 earthquake Wednesday evening, December 2, at 5:59 p.m. HST. This animated image file (GIF) continuously loops two consecutive webcam images from 5:50 p.m.

KWcam webcam image from December 2 at 6:00 p.m. HST, immediately following a M3.1 earthquake at Kīlauea summit. Several rockfalls down the talus slope impacted the summit water lake, causing some brief localized color changes of the lake surface (circled in yellow).

The U.S. Geological Survey St. Petersburg Coastal and Marine Science Center is conducting research to guide the restoration and recovery of the threatened elkhorn coral, Acropora palmata, in Dry Tortugas National Park and throughout the western Atlantic.

Restoring areas infested with invasive species that carry catastrophic fire is a top priority for the Restoration Assessment and Monitoring Program for the Southest (RAMPS) and our partners.

Tephra layers preserved at the summit of Kīlauea from at least three different eruptions. Deposits below the top of the scale are predominantly juvenile and deposits above it containing many lithics. Notice the larger size of the yellow pumice clasts compared to the much denser and finer grey lapilli and ash surrounding them from 7 to 18 on the scale.

Tropical Storm Eta affected beaches along Florida's Gulf Coast in November 2020. Some dunes were eroded up to several feet due to the high water levels associated with the storm. Madeira Beach is home to many people and animals, and erosion events such as this can affect both habitat and infrastructure.
