Inside the crater of Pu‘u ‘Ō‘ō, the "trough" is the drained lava pond of September–October 1999. The central portion of the trough was briefly filled with lava in February 2000.
Wahinekapu (Steaming Bluff) and the Steam Vents area
The weather was overcast during an overflight of Kīlauea's summit on September 23, 2020. This view shows Wahinekapu (Steaming Bluff) and the Steam Vents area within Hawai‘i Volcanoes National Park. Extensive cracks in the area allow heated groundwater to escape from underground. Cracks reach up to 63 degrees Celsius (145 degrees Fahrenheit), preventing trees from growing.

Kīlauea summit gravity survey - September 23, 2020
On September 23, 2020, Hawaiian Volcano Observatory geophysicists and a geologist conducted a gravity survey of Kīlauea summit, as part of HVO's regular monitoring program. In this photo, scientists are carrying survey equipment westward along the remnants of the Halema‘uma‘u Trail on the down-dropped block of Kīlauea caldera. The fissure from the 1954 eruption can be seen

Kīlauea summit gravity survey - September 23, 2020
During a gravity survey, HVO scientists measure the relative strength of gravity (gravimeter, bottom left corner of photo) between benchmarks. High-precision vertical positions from kinematic Global Positioning System (GPS, tripod and antenna middle of photo) help correct the gravity measurement for the effects of elevation changes. The south sulfur banks, exposed during

Kīlauea summit gravity survey - September 23, 2020
A gravimeter makes a measurement at a benchmark situated among lava flows erupted in 1919. The strength of gravity varies with both elevation and the amount of mass beneath the instrument. Changes in mass can indicate changes in the amount of magma entering Kīlauea's magma reservoirs. USGS photo by A. Flinders.
Kīlauea summit gravity survey - September 23, 2020
An HVO geophysicist takes a gravity measurement at a benchmark near a continuous gravimeter (inside hutch). The continuous gravimeter takes gravity measurements once per second and relays the data via radio back to HVO. During the gravity survey on September 23, 2020, HVO scientists took measurements at multiple locations on the floor of Kīlauea caldera. By comparing the

Views of Kīlauea's growing summit water lake
A helicopter overflight on September 23, 2020, provided airborne views of the water lake at the summit of Kīlauea Volcano. Visual and thermal images collected during the overflight are used for mapping the slowly enlarging lake. A segment of the video shows the remains of Crater Rim Drive, a portion of which collapsed during the 2018 summit activity. USGS video by M.
Kīlauea Volcano summit water lake color zones on September 18, 2020
The color zones on the lake surface shift from minute to minute. This video shows how the color zones were creating a large swirl in the lake center. USGS video by M. Patrick.
Color variations at Kīlauea's summit water lake - 09/18/2020
Color variations are common at Kīlauea's summit water lake, and are usually dominated by tan and brown hues. Today, the interaction between different color zones produced a large swirl in the center of the lake.
Map of the USGS Hawaiian Volcano Observatory’s current camera network
Map of the USGS Hawaiian Volcano Observatory’s current camera network coverage. Lava-flow hazard zone 1 is outlined in yellow. Color-shaded areas are visible to at least one camera in the current network. We would like to expand the network so that it covers the grey-shaded areas in zone 1 as well. If your property has a good view of unshaded areas in zone 1, and you

The USGS Volcano Notification Service (VNS) is a free service that sends automatic notices (emails or texts) about volcanic activity at U.S. monitored volcanoes, including Hawaiian volcanoes. You can sign up to receive these notifications at http://volcanoes.usgs.gov/vns/.
Changes on Kīlauea Volcano's East Rift Zone
Kīlauea summit lava lake level drops with deflation
Repeated overflows onto the Halema‘uma‘u crater floor
The past few weeks have been exciting for volcano watchers on the Island of Hawai‘i, especially for visitors to Hawai‘i Volcanoes National Park’s Jaggar Museum overlook, where views of the active summit lava lake within Halema‘uma‘u have been spectacular.
Large overflow onto Halema‘uma‘u crater floor
Continued overflows from the summit lava lake throughout Wednesday
Kīlauea summit lava lake overflows onto Halema‘uma‘u crater floor
Small overflows from Kīlauea's summit lava lake overnight
High summit lava lake close to the rim
In recent years, scientists have made significant improvements in developing sophisticated models of how volcanoes work. The ultimate goal is to develop models that allow us to forecast new activity.
