Eruption Quick Take: Kīlauea’s Shrinking Lava Lake

Kīlaueaʻs open lava lake surface has shrunk by almost 25% over the past week, and gas emissions decreased as low lava output continues. According to our estimates based on USGS photos, time-lapse sequences, and map area calculations, the area of active lava on the surface has shrunk by close to 20% on the lake's southwest margin and 5% on its northeast margin. We examine the lake shrinking through various new time-lapse productions, using web captures, monitoring data, and photos of Kīlauea's ongoing eruption available courtesy of the USGS Hawaiian Volcano Observatory. This short video summarizes the main points in our most recent Kīlauea live update, which includes more in-depth discussion for those interested.
