(BIVN) – A tall and dark plume was observed at the summit of Kilauea volcano on Tuesday morning.

Residents up and down Puna mauka saw the cloud drifting to the southwest, over the Ka’u Desert

“This morning, the plume from Overlook vent inside Halemaʻumaʻu is steady and gray due to its ash content,” the USGS Hawaiian Volcano Observatory stated at 8:13 a.m. “The plume is rising several thousand feet above the ground and drifting to the southwest. Ashfall is occurring in the upper Kaʻū Desert and downwind.”

“Depending on wind conditions, dustings of ash may occur in the Kilauea summit area and downwind. More energetic ash emissions are possible if explosive activity commences,” the scientists said.

The National Weather Service issued this statement at 7:45 a.m. on Tuesday:

The web camera at Kilauea Volcano Summit at showed a burst in volcanic ash emissions from Halemaumau Crater (19.4N 155.3W) beginning around 7 am HST this morning. Northeast winds will carry ash downstream across the Big Island Kau District affecting the Punaluu, Wood Valley, Naalehu communities this morning and into early afternoon. Avoid excessive exposure to ash which is an eye and respiratory irritant. Those with respiratory sensitivities should take extra precaution to minimize exposure.

The Hawaiian Volcano Observatory has cautioned about the possibility of an explosive eruption at Halemaʻumaʻu, caused by the withdrawal of lava from Halemaʻumaʻu’s summit lake, which leads to a steam-driven eruption. Such an eruption could generate ash plumes as high as 20,000 feet. The area affected by ash plumes could be as wide as 12 miles.
