Description

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 14-21, 2016. Images courtesy of USGS/HVO
