Detailed Description
A USGS scientist maps the eastern margin of the 2022 Mauna Loa eruption lava flow on December 1, 2022. In this area, the flow height is between 3 and 5 meters (10 to 16 feet) tall. The large block immediately to the right of the scientist likely rolled off from the lava flow a few hours before this photograph was taken, as the block was slightly above ambient temperatures. USGS scientists returned to this area on December 2 and observed that the lava flow margin in this area had not advanced between the two visits. USGS photo by N. Deligne.
