Before and after wildfire mitigation
This before and after image shows the same area before and after dense trees and brush were cleared for wildfire mitigation efforts. The WiRe (Wildfire Research Team) conducts research to support these mitigation efforts and other components of wildfires and communities.

Changes at Halema`uma`u Over Time
This is a comparison of photos taken from the same location in the Volcano House on May 19 and June 13, 2018. The focal length of the lens for each photo is almost the same. The photos show the enlargement of Halema‘uma‘u laterally and vertically. Note how much lower the rim is relative to the tree in the lower photo.

Flooding on the French Broad River
North Carolina saw heavy rainfall in the second half of May 2018 as a result of Subtropical Storm Alberto. These images from the European Space Agency's Sentinel-2B satellite, captured on May 12 and June 1, 2018, highlight flooding along the French Broad River near the Henderson County community of Etowah.

Lava fountaining at the west vent—October 14, 2021
A close-up photo of the vent in the western wall of Halema‘uma‘u, taken during the ongoing eruption at Kīlauea summit. The top of the 5–6 m (16–20 ft) tall lava fountain could be seen from the west crater rim on October 14, at 2:05 p.m. The lava fountains continue to build up a spatter cone around the vent.

Eyes on Earth Episode 60 – Landsat 9 Launch Part 1
Landsat 9 launched into orbit from Vandenberg Space Force Base on Monday, September 27, 2021, to carry on the legacy of a nearly 50-year record of continuous Earth observation that began in 1972. The days leading up to the event saw guests from around the world descend upon Santa Barbara County in California to watch the historic event take place.

October 13, 2021 — Kīlauea summit eruption
A view of the western portion of the lava lake within Halema‘uma‘u, at the summit of Kīlauea. This photo, taken from the west crater rim, shows the active west vent (lower right), the main island (upper left), and the old west vent from the Dec. 2020–May 2021 eruption (lower left).

U.S. River Conditions, July to September 2021
This is an animation showing the changing conditions of USGS streamgages from July 1, 2021 to September 30, 2021. The river conditions shown range from the driest condition seen at a gage (red open circles) to the wettest (blue closed circles). A purple outer ring around a gage indicates it is flooding.

Eruptive activity in Halema‘uma‘u crater—October 12, 2021
Eruptive activity continues at the west vent in Halema‘uma‘u crater, at the summit of Kīlauea. When this video was taken on October 12, a small subordinate vent was present on the north side of the main fountaining vent. The main fountaining source was supplying lava into the lake via a short spillway.

Kīlauea summit eruption - October 12, 2021
A view of the fountaining at the west vent in Halema‘uma‘u crater, at the summit of Kīlauea. The photo was taken from the west rim, looking down upon the vent. Low fountaining and roiling within the cone supplied lava to the lake via a narrow spillway. Lava spreading out into the lake develops a zig-zag pattern in the surface crust. USGS photo by M.

Kīlauea summit eruption - October 12, 2021
Associated with an increase in fountaining activity at the main western vent in Halema‘uma‘u, a short-lived vent opened just to the north (right). Activity at this vent lasted about 10 hours with low-level fountaining about 3 meters (10 ft) high.

Kīlauea summit eruption - October 12, 2021
Lava fountains from the western vent within Halema‘uma‘u continue to supply lava into the lava lake through a short spillway. Consistent fountain heights of 10–15 meters (30–50 ft) were interrupted by frequent larger busts of spatter exceeding the height of the cone (30 m or 100 ft). USGS photo taken by B. Carr on October 12, 2021.
