Lava moving down Makamae Street in Leilani Estates at 9:32 a.m. on May 6, 2018.

 A lava flow moves on Makamae Street in Leilani Estates at 09:32 am local time, on May 6, 2018.

A new fissure erupted this evening near fissures 2 and 7, beginning with small lava spattering at about 8:44 p.m. HST. By 9:00 p.m., lava fountains as high as about 70 m (230 ft) were erupting from the fissure.

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.

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 10:00 a.m. HST today (May 5).

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.

At 10:30 HST, ground shaking from a preliminary magnitude-5.0 earthquake south of Pu‘u ‘Ō‘ō caused rockfalls and possibly additional collapse into the Pu‘u ‘Ō‘ō crater on Kīlauea Volcano's East Rift Zone. A short-lived plume of ash produced by this event lofted skyward and dissipated as it drifted southwest from Pu‘u ‘Ō‘ō.

Puna residents reported to HVO geologists the recent appearance of ground cracks on a couple of roads in and around Leilani Estates. No steaming or heat were observed to originate from the cracks, and the cracks are currently still small (no more than several inches across).

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.

Within hours of the Pu‘u ‘Ō‘ō crater floor collapse, HVO's monitoring instruments recorded increased seismicity and ground deformation along Kīlauea Volcano's East Rift Zone (ERZ) that continued through the night. These signals indicated an intrusion of magma from the Middle ERZ toward the Lower ERZ, extending from Pu‘u ‘Ō‘ō to at least Highway 130.

This map shows recent changes to Kīlauea's East Rift Zone lava flow field and Pu‘u ‘Ō‘ō cone. The 61g flow field, as of April 13, 2018, is shown in pink. The crack that formed on the west side of Pu‘u ‘Ō‘ō on April 30th, 2018, during or immediately after the crater floor collapse is shown as a solid black line.

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.
