![]() After 5 months of activity, a decrease in effusion indicated that the eruption in Halema‘uma‘u at the summit of Kīlauea was going to pause. HVO field crews did not observe any signs of lava lake activity on May 25, and reported no signs of active surface lava. The next day Kīlauea was no longer erupting. The crusted-over lava lake was last measured at 229 m (751 ft) deep and was stagnant across its surface. Below are select photographs and videos from the eruption, as it progresses.

The western vent feeding the lava lake in Halemaʻumaʻu became partially submerged in the first days of January. The result is a rolling upwelling of lava called a "dome fountain." The height of the dome fountain was estimated to be about 16 feet (5 m) with an estimated width of 33 feet (10 m). Note: this telephoto image was taken by scientists studying the eruption and this view is not available from publicly accessible areas. Video by the USGS Hawaiian Volcano Observatory.

As of 11:20 a.m. on December 21, two of the three original vents were still active, feeding the lava lake. The northern vent (right side) would soon be submerged.

Some areas still remain unstable after the eruption of 2018, and seismic activity is always a possibility on an active volcano. ![]() WebcamsGet a live look inside the park, courtesy of USGS Hawaiian Volcano Observatory ![]() Ranger Tips For A Successful VisitA new eruption at the summit of Kīlauea is drawing large numbers of visitors.
