Aerial view of fissure 13 shortly after it opened this afternoon. The spattering fissure cut across Leilani Street, between Kahukai and Pohoiki Road.

This video of Halema‘uma‘u lava lake from this evening shows the agitated lake surface caused by intemittent rock falls. Falling rocks are common since the lava lake level has dropped quickly, and exposed the walls.

Aerial view of fissure 12 at 1:15pm HST today. Bursting gas bubbles blasted spatter (bits of molten lava) skyward, with some fragments reaching as hight as the tree tops. This fissure opened in the forest south of Malama Street in Leilani Estates.

Aerial view of fissure 8 in Leilani Estates as of mid-afternoon today. After vigorously erupting for much of the day, activitiy on the fissure diminished around 4:00pm. A lava flow from the fissure advanced about 1 km (0.6 mi) to the northeast.

Fissure eruption on Luana Road, between Leilani and Malama, in the Leilani Estates subdivision, at 9:37 p.m. HST on May 5, 2018. Fountains reached heights of up to 100 m (about 330 feet)

Fissure 3 opened around 6:00 a.m. HST on Friday, May 4, with weak fuming from a crack on Kaupili Street. This fuming increased, as did rumbling sounds. Eventually spatter was ejected and accumulated around the fissure. Large, loud bubble bursts were common at this fissure.

Fissure 2 opened around 1:00 a.m. HST on Friday, May 4, with a small area of spattering in a residential driveway. Within an hour the spattering was more vigorous, with spatter reaching about 30 meters (100 feet). This spatter was thrown over the power lines and landed on Makamae Street.

This small fissure = opened in the Leilani Estates subdivision on the lower East Rift Zone of Kilauea Volcano around 5:00 p.m. Lava erupted from the fissure until about 6:30pm, when it became inactive.

This time-lapse video from 7:30 p.m. April 25 to 7:30 p.m. April 26 shows Halema‘uma‘u lava lake producing intermittent overflows onto the crater floor. The largest of these flows was from approximately 6:15 a.m. to 10:30 a.m. on April 26 and covered about 90 acres (2/3) of the crater floor.

Vigorous overflows from Kīlauea's summit lava lake covered a large portion of the floor of Halema‘uma‘u this morning. In this video, the view starts from the north and heads south, showing the north and east sides of Halema‘uma‘u crater.

On Kīlauea Volcano's summit, the Halema‘uma‘u lava lake's high standing lake level produced intermittent overflows onto the crater floor.

USGS–Hawaiian Volcano Observatory research geologist Matt Patrick talks about the lava lake in the Halema‘uma‘u Crater at the Kīlauea Volcano (Hawaii). Dr. Patrick describes the eruption that created the lava lake and points out features of the lake including moving crustal plates, gas bursts, spatter and collapse scars on the crater rim. Dr.
