At approximately 3:20 p.m. HST on September 29, 2021, the USGS Hawaiian Volcano Observatory (HVO) detected glow in Kīlauea summit webcam images indicating that an eruption has commenced within Halemaʻumaʻu crater in Kīlauea’s summit caldera, within Hawai‘i Volcanoes National Park.

This reference map depicts the ongoing Kīlauea summit eruption as of approximately 6:00 PM on September 29, 2021. Several new fissures (orange lines) within Halema‘uma‘u have erupted enough lava (red) to cover nearly all of the 12/2021–5/2021 lava lake by more than 36 ft (11 m).

This timelapse image sequence shows the opening sequence of the new eruption in Halema‘uma‘u crater, at the summit of Kīlauea. The first few moments are shown on a loop several times to highlight the visible uplift of the crater floor, just before the appearance of new fissures.

Landsat 9 is the latest in a prestigious line of satellites that have been watching our planet for nearly 50 years. They have monitored changes on land and made that information freely available to users around the world.

Tule white-fronted geese get ready to land at Summer Lake Wildlife Area in Oregon. The geese turn upside down and sideways to drop altitude quickly to land, a behavior known as "whiffling" or "maple leafing."

Two high-resolution, digital cameras were mounted on towers overlooking the beach, dunes, and instrument arrays in the Outer Banks of North Carolina on September 18, 2021, as part of the DUring Nea

Researchers from the USGS and North Carolina Universites set up their equipment on installed poles stretching from the dune to the surf zone.

To install instruments offshore professional divers were hired to work alongside USGS personnel. Here, long segments of pipe are jetted into the seafloor to which instruments will be attached to measure offshore oceanographic conditions.

USGS researcher Jenna Brown takes a measurement with a real time kinematic GPS receiver, this will give her an accurate position and height of the aluminum pole beneath it, which will have mutliple instruments attached to it to measure water flow and elevation changes.

An alternative to uncrewed aerial systems (UAS; commonly known as 'drones'), U.S. Geological Survey (USGS) scientists use helikites equipped with cameras to collect imagery of the coastline. The pictures collected by these helium-powered kite-balloons are used to create a 3D digital elevation map of the beach.

USGS scientists mounted this high-resolution digital camera on an observation tower in the dune at the U.S. Army Corps of Engineers Field Research Facility near Kitty Hawk, North Carolina. The camera overlooks the beach, dune, and an instrument array, and collects images throughout calm and storm conditions.
