October 28, 2022 — Mauna Loa Overflight, 1940 Eruption Cone
Detailed Description
The 1940 eruption of Mauna Loa began and remained within Moku‘āweoweo, the summit caldera. The eruption was approximately 164 days in duration, and created a lava lake within the caldera. Today, only the cone from that eruption remains visible above the 1984 lava flows that surround it on the caldera floor. USGS image by K. Mulliken.
