Detailed Description

A UAS (Unmanned Aircraft Systems) mission during this past week documented the widening of the Overlook ventEarthquakes in the Kīlauea Volcano's summit region continue as the area subsides and adjusts to the withdrawal of magma. The vent is widening due to the collapse of the steep enclosing walls and rim. Large rockfalls from these areas have triggered explosive events that produce minor amounts of ashfall downwind. The video surveys the southeast rim of the Overlook vent to the old Overlook parking lot, showing cracks in the rim and areas dusted with ash. Limited UAS flights into this hazardous area are conducted with permission and coordination with Hawai‘i Volcanoes National Park. The information is used to quantify change and informs our assessment of hazards, which is shared with the National Park Service and emergency managers.

Kīlauea Volcano Summit

UAS Survey of the Overlook Vent's Southeast Rim

May 26, 2018

At Kīlauea Volcano's summit, a nearly continous plume of steam and other gas billows out of the overlook vent and drifts with the wind.

Earthquakes in the summit region continue as the summit area subsides and adjusts to the withdrawal of magma. A UAS mission during this past week documented the widening of the Overlook vent due to the collapse of the steep enclosing walls and rim. Large rockfalls from these areas have triggered explosive events that produce minor amounts of ashfall downwind. Explosions are possible at any time.

This video was taken from a UAS (Unmanned Aircraft Systems). Limited UAS flights into this hazardous area are conducted with permission and coordination with Hawai‘i Volcanoes National Park. The information is used to quantify change and informs our assessment of hazards, which is shared with the National Park Service and emergency managers.
