This image is a composite of a thermal image and a normal photograph, showing the coastal plain and pali. Red areas are warm portions of the flow field that were active in the past weeks or months, while yellow and white areas are areas of active breakouts. This image shows a handful of active breakouts scattered across the flow field, but each one is relatively small. Some of these breakouts were only weakly active. Overall, this image shows a reduced level of activity on the flow field today (July 31, 2012). (Hawaiian Volcano Observatory, USGS)
The lava pond in the northeast portion of Puʻu ʻŌʻō crater remains active, though the level of lava was low in the pit today. Over this past weekend, a small collapse of the rim enlarged the pit slightly. The lava pond is about 30 meters (100 feet) wide. (Hawaiian Volcano Observatory, USGS)
This is the latest image is from a temporary research camera positioned at the Halemaʻumaʻu Overlook Vent. (Hawaiian Volcano Observatory, USGS)
This is the latest image from a temporary thermal camera. 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. (Hawaiian Volcano Observatory, USGS).
