Lava fountains - western fissure, Halema‘uma‘u, Kīlauea - Oct 5, 2021

Lava fountains from the western fissure vent in the Halema‘uma‘u crater wall, at Kīlauea's summit during the ongoing eruption. The shaking at the end of the video is due to strong wind gusts moving the tripod. This video clip was recorded on October 5, 2021, from the southern crater rim.

Kīlauea summit eruption in Halemaʻumaʻu crater - October 4, 2021

A telephoto view of fountaining at the western vent in Halema‘uma‘u crater, at the summit of Kīlauea. Spatter from the fountain has built a horseshoe-shaped cone around the vent in the western crater wall. Molten spatter accumulating on the cone forms a tiny stream of lava down the north side (bottom center). This photo was taken on October 4, 2021, from the northwest

Kīlauea summit eruption in Halemaʻumaʻu crater - October 4, 2021

A brief gap in the fume provides a clear view of the fountaining at the western vent in Halema‘uma‘u crater, at the summit of Kīlauea. Sulfur dioxide (SO2) emission rates remain elevated and were measured at approximately 7,000 tonnes per day on October 4. USGS photo taken by M. Patrick from the southern crater rim on October 4, 2021.

Kīlauea summit eruption in Halemaʻumaʻu crater - October 4, 2021

KWcam image taken on October 4, 2021, just before 6 a.m. HST. This image shows the ongoing eruption within Halemaʻumaʻu crater at the summit of Kīlauea. The eruption began the afternoon of September 29, 2021, as fissures in the floor of the crater; this activity is generating a lava lake that is slowly filling the crater. Near-real-time images captured by the KWcam are

Kīlauea summit eruption in Halemaʻumaʻu crater - October 4, 2021

The eruption continues in Halema‘uma‘u crater, at the summit of Kīlauea. This video shows the dominant fountain at the west vent, from two different angles, as well as the smaller fountaining source emerging through the lava lake.

Kīlauea summit eruption in Halemaʻumaʻu crater - October 4, 2021

This zoomed-in view of the erupting western fissure in Halema‘uma‘u shows lava fountaining activity on the morning of October 4, 2021. The fountains have built a C-shaped spatter rampart around their source, which is now submerged in the rising lava lake. Using a laser rangefinder, HVO field crews measured the spatter rampart to be standing 20 m (66 ft) above the

This photo, captured on the morning of October 4, 2021, provides a zoomed-in view of the eastern edge of the main island in the Halema‘uma‘u lava lake. In the earliest days of the ongoing Kīlauea eruption, this was the site of an energetic eruptive vent that showered the island with spatter and tephra. Activity had waned substantially, but not completely: volcanic gases

Kīlauea summit eruption in Halemaʻumaʻu crater - October 4, 2021

A telephoto view of foundering in the active lava lake within Halema‘uma‘u crater, at the summit of Kīlauea. Foundering occurs when denser and cooler solidified crust (black) sinks below less dense liquid lava (orange). Photo taken at 7:48 a.m. HST on October 4, 2021. USGS photo by J.M. Chang.

A wide view of the lava lake in Halema‘uma‘u crater, at the summit of Kīlauea, taken from the western crater rim. The western vent (lower right) remains the dominant source of fountaining, while low lava fountains are still emerging through the southern portion of the lava lake (center right). USGS photo by M. Patrick taken on October 4, 2021.

A telephoto image of fountaining from the western vent in Halema‘uma‘u crater, at the summit of Kīlauea. Spatter from the fountain continues to build up a cone around the vent, which is almost entirely out of view from this angle. This photo was taken from the western crater rim on October 4, 2021.

May 3rd marks three years since the start of the devastating lower East Rift Zone eruption of Kīlauea. In 2018, rising summit lava lake levels, caused by building magmatic pressure, culminated in a large eruption on the lower flank which then abruptly drained the summit lava lake and initiated crater collapse.

Gravimeters, essentially extremely precise pendulums, can measure a change in the force of gravity to one-in-one billionth of the force you feel every day. This force varies based on the distance and the amount of mass between the instrument (or you) and the center of the Earth.
