This animated gif shows one year of reference maps depicting the ongoing Kīlauea summit eruption, which began on September 29, 2021. The animated gif shows how the active lava lake has decreased in area over the past year, while the crater floor has grown in area.

KWcam image taken on September 27, 2022. The floor of Halemaʻumaʻu has grown in area and elevation due to the ongoing eruption in crater. The island that formed on December 20, 2020, is surrounded by younger lava flows so what is seen on the surface of Halemaʻumaʻu crater floor today represents the oldest and youngest deposits from these recent eruptions!

Following a slight drop in the lava lake and subsidence of the crater floor on September 20, at the summit of Kīlauea, the lava lake level has remained several meters (above ten feet) below its rim. USGS photo by M. Patrick on September 23, 2022.

On September 20, 2022, a slight drop in lava lake level at the summit of Kīlauea resulted in stagnation of the small lava pond that was supplied by the main lava lake. The drop in lava level left a narrow bridge of solidified lava over the pathway between these two areas USGS photo by M. Patrick.

The west vent remains active in Halema‘uma‘u, at the summit of Kīlauea. The vent area consisted of several small spatter cones with incandescent openings, along with weak, sporadic, spattering. USGS photo by M. Patrick.

This animated gif of images from the thermal F1cam on the west rim of Halemaʻumaʻu crater shows changes to the crater floor from September 20-21, 2022. Increased seismicity and ground deformation rates likely represented a temporary blockage in the eruption of lava at Halemaʻumaʻu, causing pressurization below the surface.

This animated gif of images from the B1cam on the east rim of Halemaʻumaʻu crater shows changes to the crater floor during the afternoon of September 20, 2022. The lava lake level dropped 23-feet (7-meters) and the crater floor surrounding the lava lake also subsided by several yards (several meters). USGS animated gif.

As HVO geologists pulled up in the car to make measurements of the Halema‘uma‘u lava lake the morning of September 15, 2022, this was the spectacular sight that met them at the end of Crater Rim Drive. Steam rose from ground cracks across Kīlauea caldera and clouds were spilling over the eastern caldera rim.

The steaming summit lava lake of Kīlauea in the 7 a.m. morning light of September 15. HVO geologists heard the west vent softly puffing and an insistent high-pitched hissing from the steaming northeastern embayment of the active lava pond in Halema‘uma‘u. A deeper toned hiss occasionally joined in from somewhere on the eastern side of the lake.

The western vent in Halema‘uma‘u was steaming heavily the morning of September 15. A small glowing spot could be seen when looking through the laser rangefinder instrument, which is used to measure distances. This close-up view also revealed a small blanket of tephra on the slope of the cone that has been created by spattering at the vent.

This reference map depicts the ongoing Kīlauea summit eruption on September 13, 2022. One eruptive vent (orange) is active within Halema‘uma‘u, on the western side of the crater floor. An adjacent pond (purple) is feeding lava to a larger lake (red) via a crusted-over tube.
