Kīlauea images of eruptive activity, field work, and more.
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.

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.

The summit lava lake has dropped significantly over the past few days, and, as of the evening of 5/6/18, was roughly 220m below the crater rim. This very wide angle camera view captures the entire north portion of the Overlook crater.

This map shows the locations, mapped by USGS-HVO scientists, of eruptive fissures in the order that they occurred in the Leilani Estates Subdivision as of 6:00 a.m. HST today (May 6).

This map shows the locations of eruptive fissures on Kīlauea Volcano's East Rift Zone in the order that they occurred in the Leilani Estates Subdivision as of 6:00 a.m. HST today (May 6). The blue lines are paths of steepest descent that identify likely paths of a lava flow, if and when lava moves downhill from an erupting vent.

New fissures opened up on Hawaii’s Big Island in early May 2018, spouting lava that destroyed homes in the Leilani Estates neighborhood.

With each large earthquake, ground shaking causes additional collapse within the Pu‘u ‘Ō‘ō crater, sending a plume of reddish-brown ash skyward. The size and vigor of a plume depends on the size of the earthquake and subsequent collapse. This roiling ash plume followed the magnitude-6.9 earthquake on May 4.

An intrusion of magma into Kīlauea Volcano's lower East Rift Zone resulted in an eruption in Leilani Estates in the lower Puna District on the Island of Hawai‘i. The first four fissures to erupt in the subdivision are shown here on May 4, emitting copious amounts of hazardous sulfur dioxide gas.

Kīlauea's summit eruption within Halema‘uma‘u did not initially respond to the volcano's East Rift Zone activity (collapse of the Pu‘u ‘Ō‘ō crater floor and magmatic intrusion into the rift zone) on April 30. But on May 2, the lava lake level began to drop in concert with summit deflation, suggesting that magma was moving from the summit into the East Rift Zone.

The start of fissure 3 during Kīlauea's lower East Rift Zone eruption. Lava erupting to the surface cut across Kaupili Street around 7:00 a.m. on May 4, 2018.

This map shows the locations, mapped by USGS-HVO scientists, of the three eruptive fissures in the order that they occurred in the Leilani Estates Subdivision as of 8:00 a.m. HST today (May 4). The fissures are jetting copious amounts of sulfur dioxide gas, which should be avoided.

When Kīlauea Volcano's lower East Rift Zone first erupted on May 3, 2018, lava temperatures were about 2000 degrees Fahrenheit. As the eruption progressed, with fresher magma feeding the fissures, the erupted lava became progressively hotter, resulting in more fluid and far-reaching lava flows (May 21 shown here).

Pu‘u ‘Ō‘ō on May 3, 2018, as viewed from the helicopter overflight. The crater floor is collapsed, and a thin plume escapes from the gaping crater. The west flank cracked on April 30th around 2:30 pm HST, and minor amounts of lava oozed out of the crack (line of steaming features) just before the plumbing system catastrophically failed.

Over 500 earthquakes were located by the USGS Hawaiian Volcano Observatory (HVO) between noon Friday and noon Saturday, May 4-5, 2018. A magnitude-6.9 earthquake at 12:32 p.m. HST on Friday was preceded by two foreshocks with magnitudes of 5.4 and 4.4 at 11:32 a.m.

As of this afternoon (May 1), the eruption at the summit of Kīlauea has apparently not been affected by the collapse of Pu‘u ‘Ō‘ō or intrusion of magma along the volcano's Lower East Rift Zone.

Just before 10:00 a.m. today (Monday, April 30), a break in the weather allowed HVO's webcam to capture this image of the lava lake within Halema‘uma‘u at the summit of Kīlauea. Following multiple overflows of the lava lake last week, the lake level dropped over the weekend in concert with the switch to summit deflation.

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.
