An east-facing view showing Nāpau Crater in the background and the recent eruption in the foreground. This brief eruption took place on the middle East Rift Zone of Kīlauea over about an hour during heavy rain that obscured webcam views the evening of September 15, 2024. USGS photo by M. Zoeller. 

This thermal map shows two small lava pads erupted late on September 15, just west of Nāpau Crater on the East Rift Zone of Kīlauea. This small eruption resulted from magma intruding from the summit into the East Rift Zone, and was associated with an increase in earthquake activity along the East Rift Zone.

This map shows recent deformation at Kīlauea over the timeframe of September 2–14, 2024. Data were acquired by the European Space Agency's Sentinel-1A satellite. Colored fringes denote areas of ground deformation, with more fringes indicating more deformation. Each color cycle represents 2.8 cm (1.1 in) of ground motion.

At repeater station KOHD, USGS Hawaiian Volcano Observatory field engineers upgraded the seismic sensor and digitizer. The instrument is located in a vault, which protects it from environmental noise, such as wind. USGS photo by J. Chang.

A USGS Hawaiian Volcano Observatory (HVO) field engineer replaces the power cable at the KOHD repeater station. HVO field engineers maintain the network of instruments that allow HVO to monitor volcanic activity and earthquakes in Hawaii. Working with HVO IT-specialists, they ensure that each monitoring station functions and can relay data back to the observatory.

Repeater station KOHD receives data from monitoring stations nearby and relays it back to the Hawaiian Volcano Observatory. The site is located on Kohala volcano, which last erupted over one hundred thousand years ago. The verdant pu‘u (hills) that are cinder cones erupted by Kohala are visible in the background of this photo. USGS photo by K. Mulliken.

At the Hualālai repeater station, USGS Hawaiian Volcano Observatory field engineers installed a voice repeater that will enable radio communications between disparate locations. USGS photo by M. Warren.

The Hualālai repeater site is located on the southeast side of Hualālai volcano, which erupted most recently in 1800-1801. At an elevation of 2,160 meters (7,090 feet) above sea level, the repeater site is often enshrouded in fog. A suite of solar panels is used to generate power for the site, stored locally in lithium batteries. USGS photo by M. Warren.

Remote volcano monitoring stations on the Island of Hawai‘i are powered via solar panels that charge a suite of batteries. The power system at the Hualālai repeater station, which relays data from nearby stations back to the observatory, was upgraded in 2023 to use lithium batteries (white boxes in the photo).

The map on the left shows recent deformation at Kīlauea over the timeframe of August 9–21, 2024. Data were acquired by the European Space Agency's Sentinel-1A satellite. Colored fringes denote areas of ground deformation, with more fringes indicating more deformation. Each color cycle represents 2.8 cm (1.1 in) of ground motion.

USGS scientists visited the KWcam webcam, at the summit of Kīlauea, to replace the desiccant packs that keep the webcam enclosure dry. Despite ongoing earthquake activity in the upper East Rift Zone of Kīlauea, activity beneath the summit caldera was quiet today. USGS photo by M. Patrick.

USGS scientists made a routine visit to the summit of Kīlauea for maintenance work on a webcam and general observations. The weather offered clear views of Kaluapele (the summit caldera), and only minor outgassing from several spots on the caldera floor. USGS photo by M. Patrick.

This map shows recent deformation at Kīlauea, over the timeframe of August 7-19, 2024. Data were acquired by the European Space Agency's Sentinel-1A satellite. Colored fringes denote areas of ground deformation, with more fringes indicating more deformation.  Each color cycle represents 2.8 cm (1.1 in) of ground motion.

This reference map depicts the features on Kīlauea's middle East Rift Zone, much of which is within Hawaiʻi Volcanoes National Park. Pit craters and lava flows are evidence of a long history of magma moving along this rift zone pathway. Numerous eruptions took place in this region during the 1960s–1970s.

A Hawaiian Volcano Observatory gas scientist works to install a newly calibrated Multi-Gas instrument at the Sulfur Cone site. At an elevation of 3,430 meters (11,240 feet) above sea level, the air is rare! Working conditions are far more strenuous for HVO field teams at these high elevations due to the much lower levels of oxygen in the air to breathe.
