At 8:00 a.m. HST. A slow sticky a'a flow emerges from a new fissure just over a half mile northeast of the end of Hinalo Street. The new fissure - fissure 17 - is about one half mile south of Hwy 132. Some reports have referred to this fissure as number 18 but that is not correct. Fissure 18 had not erupted by this time.

At 2:00 p.m. HST. This photo reveals a small pad of lava between Fissures 16 and 17 which did not appear in photos of the same scene taken this morning. (Red arrow points to the lava pad.) From the photo it appears that this fissure had stagnated. We have designated this small outbreak as Fissure 18.

Map as of 9:00 a.m. HST, May 13, shows the location of fissure 17, which opened this morning at approximately 4:30 a.m. HST. NOTE: This new fissure was initially referred to as fissure 18 in early reports, but that is incorrect (what was called fissure 17 yesterday did not erupt lava, so this morning's erupting fissure is actually 17).

Aerial view of fissure 17 around 4:30 p.m. HST. On the west end of the flow, intermittent percussive jetting threw spatter and lava bombs up to 500 feet above the ground. East margin of the ‘a‘ā flow was cascading into a pit or graben.

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.

Landsat and Sentinel sensors capture the Rattlesnake Fire as it burns in Arizona.
At the USGS EROS Center, we study land change, operate the Landsat satellites, and maintain the longest, continuously acquired collection of images of the Earth's land surface.

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.

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.
