Close view of rock hurled from the Overlook crater during an explosive event last evening. The rock broke apart on impact, and was about 60 cm (24 in) before it hit the ground. The location is a few hundred meters (yards) south of the Overlook crater at the Halema‘uma‘u parking lot.

For the past several days, intermittent small explosions have occurred at the west end of Fissure 17. These explosions throw large pieces of spatter to a height of about 150 m (500 ft).

Real-time flow meter installed on a center-pivot irrigation well in Mississippi County, Arkansas as part of a cooperative project conducted between USGS and the Arkansas Natural Resources Commission. The meter will measure water use for irrigation, providing data which will help improve water-use information in other locations as well.

Ash from an explosive event at Halema‘uma‘u on May 15, 2018, was blown by trade winds to the southwest, where it fell from the plume and blanketed the Ka‘ū Desert landscape. Samples of this ash were collected for ash leachate analyses as part of the assessment of hazards from Kīlauea Volcano's eruption.

Incandescence observed at Fissure 14 around 10:30 a.m. HST. Pulsing, gas-rushing sounds could be heard coming from the crack. Yellow sulfur deposits appear on the crack margins.

Map as of 6:45 a.m. HST, May 15, shows the location of the 'a'ā lava flow spreading from fissure 17; the flow front at the time is shown by the small red circle with label. The flow is following well a path of steepest descent (blue line), immediately south of the 1955 'a'ā flow boundary.

At 1:38 p.m. HST, another dark ash plume rose from the Overlook crater. During a flight earlier today by the Civil Air Patrol, the height of the ash plumes near the crater rose to more than 3 km (9,800 ft) above sea level, and downwind the plumes continued to rise to about 3.5 km (11,500 ft) above sea level.

At 11:43 HST, Civil Air Patrol flight CAP20 reported plume tops at about 9,500 ft with the dispersed plume rising as high as 11,000 ft.

At 1:38 p.m. HST, ash falls from the plume southwest from Halema‘uma‘u crater onto the Kau desert. The northeast tradewinds were persistent today at the summit of Kīlauea Volcano, so ash was only blown southwest.
