The area of active surface lava has diminished over the past month in Halema`uma`u crater, at the summit of Kilauea. Today, active surface lava was limited to a small pond, about 20 meters (yards) long. The pond surface was normally covered with a stationary crust, but occasionally resurfaced. This video shows crustal foundering during a resurfacing event.

This close-up view of the of the Halema‘uma‘u lava lake at the summit of Kīlauea was captured on Tuesday, May 18. During an approximately one-hour visit to the crater rim, USGS Hawaiian Volcano Observatory scientists' only observation of active lava was the crustal foundering event captured here, which lasted approximately five minutes.

The lava lake in Halemaʻumaʻu crater, at the summit of Kīlauea, remains active but has diminished in area and vigor over the past month. This thermal timelapse sequence shows the changes in the lake activity over the past month. In mid-April the area of active surface lava in the lake was approximately 7.5 acres (3 hectares).

About 15 million people rely on the Delaware River Basin for drinking water, including residents of Philadelphia, PA, Camden, NJ, and Wilmington, DE. What might happen to the water supply if climate change and population growth continue unabated? How might that impact land cover and land use patterns?

On May 15, USGS Hawaiian Volcano Observatory geologists did a routine hike to the summit of Mauna Loa and inspected summit monitoring equipment. Clear weather provided good views across the floor of Moku‘āweoweo, Mauna Loa's summit caldera, and nothing unusual was observed.

The lava lake in Halema‘uma‘u crater, at the summit of Kīlauea, remains active, although surface incandescence (glowing red lava) has become less frequent over the last few days. In this view looking northwest, two elongated lobes oriented west (left) to east (right) with a relatively smooth shiny grey surface are visible in the center of the photo.

More of Kīlauea's lava lake surface in Halema‘uma‘u crater has solidified in recent weeks, as is evident in this aerial view taken yesterday, May 13. However, gas emissions and small patches of active lava on the surface indicate that the eruption continues. Most recently, gas emissions were measured as 225 tonnes per day on May 12.

A helicopter overflight on May 13, 2021, at approximately 11:30 a.m. HST allowed for aerial visual and thermal imagery to be collected of the eruption within Halema‘uma‘u crater at the summit of Kīlauea Volcano. The visual images were used to create a digital elevation model (DEM) of the crater, shown here.

The eruption in Halema‘uma‘u, at the summit of Kīlauea, continues. Gas emissions, last measured on May 12, were 225 tonnes per day. This photo, taken on May 13, shows the bluish-tinged plume of volcanic gas being emitted from the western vent complex within Halema‘uma‘u crater. USGS image by K. Mulliken.

USGS Hawaiian Volcano Observatory geologists observed fluid lava on the surface of the lava lake in Halema‘uma‘u, at the summit of Kīlauea, while monitoring the eruption on May 13. Two areas of ponded lava exhibited foundering, during which more-dense solidified crust sinks into the lava lake and is replaced by less-dense liquid lava from below.

The area of solidified crust at the surface of Halema‘uma‘u's lava lake, at the summit of Kīlauea, has been growing over the past several weeks. This may make it seem that the eruption is over but lava continues to be supplied to the lava lake from below.
