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.

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.

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.

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).

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.

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.
