MKcam image of the Kīlauea eruption plume on May 25, 2025

The Kīlauea plume from episode 23 reached heights of more than 20,000 feet (6,100 meters)— likely over 25,000 feet (7,600 meters)—above Kīlauea’s summit, which is at an elevation of about 4,000 feet (1,200 meters) above sea level.  This photo, taken from Mauna Kea and looking south, shows Mauna Loa in the right side of the photo and the Kīlauea plume rising above the clouds in the left side of the photo. The plume contained high levels of water vapor (H2O), carbon dioxide (CO2), and sulfur dioxide (SO2).  USGS webcam photo.
