Time-lapse movie from images gathered from a temporary thermal camera looking into Pu’u ‘O’o Crater. The temperature scale is in degrees Celsius up to a maximum of 500 Celsius (932 Fahrenheit) for this camera model, and scales based on the maximum and minimum temperatures within the frame. Thick fume, image pixel size and other factors often result in image temperatures being lower than actual surface temperatures. April 21-28, 2015. Images courtesy of USGS/HVO

The recent rise of the lava lake within the Halema‘uma‘u Crater vent at the summit of Kīlauea has not resulted in any significant change or increased activity at Pu‘u ‘Ō‘ō. All active flows from Pu‘u ‘Ō‘ō remain within about 5 miles of the Pu‘u ‘Ō‘ō vent, and about 8 miles from the area of Highway 130 near Pāhoa. The team at the USGS Hawaiian Volcano Observatory is maintaining close observations of all volcanic activity and the community will be kept informed of any changes in the level of volcanic threat. Presently, the Kilauea Volcano alert level remains at the WATCH or orange threat level and there is no immediate threat to any down slope communities.
