Kīlauea LERZ Fissures, May 12 at 12:00 p.m.
Main map shows the location of fissure 16, as well as earlier fissures, lava flows, and steaming areas, as of 12:00 p.m. HST, May 12. Inset map shows fissures in Leilani Estates in the order they occurred since May 3. Shaded purple areas indicate lava flows erupted in 1840, 1955, 1960, and 2014-2015.

It's an extraordinary time on Kīlauea!
To help us understand what could happen at Kīlauea Volcano's summit, we look to past similar events, but this does not mean that future events will be exactly the same. This map shows the distribution of ballistics and tephra from the 1924 phreatic (steam-driven) explosions.

It's an extraordinary time on Kīlauea!
On the morning of May 9, 2018, a large rockfall in "Overlook crater" within Halema‘uma‘u at the summit of Kīlauea triggered a gas-driven explosion that sent an ash plume several thousand feet skyward. Phreatic (steam-driven) explosions can create larger ash plumes; the 1924 explosions sent ash plumes up to 20,000 feet high. USGS photo.

HVO geologist measures temperature on Nohea Street
HVO geologist measured a temperature of 103 degrees C (218 degree F) at a crack along Nohea Street, Leilani Estates. The asphalt road was describes as "mushy" from the heat.

Kīlauea ERZ Fissure Map with Paths of Steepest Descent, May 9
This map shows the locations of fissures and an ‘A‘ā flow erupted since May 3 in the order that they occurred in Leilani Estates as of 7:00 p.m. HST, May 8. The purple areas are lava flows erupted in 1840, 1955, 1960, and 2014-2015.

Kīlauea ERZ Fissure Map as of 5:30 p.m. , May 10
This map shows the locations of fissures and an 'a'ā flow erupted since May 3 in the order that they occurred in Leilani Estates as of 5:30 p.m. HST, May 9. Note the area of heavy steaming from ground cracks that began earlier this afternoon, located west of Highway 130. The purple areas are lava flows erupted in 1840, 1955, 1960, and 2014-2015.

Ash column rises from the Overlook crater at the summit of Kīlauea Volcano. HVO's interpretation is that the explosion was triggered by a rockfall from the steep walls of Overlook crater. The photograph was taken 5/9/18 at 8:29 a.m. HST from the Jaggar Museum overlook.

New 3D model of the summit lava lake
The summit lava lake in Halema‘uma‘u crater has dropped substantially over the past week due to intrusive and eruptive activity on the lower East Rift zone. This 3D model of the crater was created from thermal images collected during a helicopter overflight on May 8. The lake at this time was roughly 295 m (970 feet) below the floor of Halema‘uma‘u Crater.

At 16:22 HST. Steaming area located uprift (west) of Highway 130. Geologists observed many steaming ground cracks in the area during two overflights this afternoon. This area is inline with fissures 1-15 (in distance, upper left in photo), but located farther west.

Thermal map of the Leilani Estates fissures
This thermal map shows the fissure system during an overflight of the area this afternoon. Fissure 15, at the northeast end of the fissure system, formed today but was only briefly active. The black and white area is the extent of the thermal map.
