Thermal video of Kīlauea's summit water lake on June 23, 2020

This thermal video shows typical activity at Kīlauea's summit water lake. Steam carried across the water surface often masks thermal features on the underlying water surface. USGS video by M. Patrick.

Use of UASs (“Drones”) in 2018 at Kīlauea and Beyond

This video describes USGS use of Unoccupied Aircraft Systems (UAS) or "drones" for use in 2018 at Kilauea Volcano in Hawaii. The speaker, Angie Diefenbach, is a leading expert in use of UAS for volcano surveillance and research. The presentation was given in June 2020 to colleagues in Ecuador who are interested in applications of UAS at their volcanoes. Angie is a member

Lahar Detection System Developments at Mount Rainier

The video describes USGS efforts to improve lahar (mudflow) monitoring at Mount Rainier, an ice-clad volcano in Washington State with potential for dangerous volcanic mudflows. The presentation was given to colleagues in the US and in Ecuador by Andy Lockhart. Andy is a geophysicist with the the USGS/USAID Volcano Disaster Assistance Program, and he has worked to reduce

Virtual flyover of Kīlauea summit

A helicopter overflight provided aerial photographs of Kīlauea caldera on May 29, and these photos were used to construct a 3D model. The water lake is visible as the tan area in the deepest portion of Halema‘uma‘u crater. For scale, the water lake is 270 m (885 ft) long and approximately 600 m (1970 ft) below the western caldera rim. USGS photos by K. Mulliken.

Video of Kīlauea summit from May 29 overflight

This wide-angle video was captured during a helicopter overflight on May 29, and skirts the southern border of Halema‘uma‘u crater. The water lake, filling the bottom of the crater, was tan and brown today, and showed no significant changes. USGS video by M. Patrick.

May 29, 2020—Thermal map of Kīlauea summit

The May 29 overflight provided updated thermal images of Kīlauea summit, covering the caldera floor and showing the warm surface of the water lake in Halema‘uma‘u crater. No significant changes were observed in the surface temperature of Kīlauea's summit crater lake. Small hotspots are also present on the walls of Halema‘uma‘u due to fumaroles. This preliminary thermal map
