It'd be better in color, but still impressive. I did find a thermal camera image, however. Don't slip and fall in!
This image is from a temporary thermal camera located on the south rim of Halemaʻumaʻu and looking steeply toward the north at the active Halemaʻumaʻu vent. The temperature scale is in degrees Celsius up to a maximum of 500 degrees (932 degrees Fahrenheit) for this camera model, and scales automatically 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.
There's a lot of pent up energy there.
