November 30, 2022 — Mauna Loa Eruption Map
The Northeast Rift Zone eruption of Mauna Loa has continued into its third full day. At this time two fissures are active, sending lava flows primarily to the north-northeast. Webcam and satellite views overnight allowed USGS analysts to accurately map some of the most active flows, displayed in red here, along with older flows further uprift and in part of Mokuʻāweoweo Caldera. Elsewhere the progression of the flows is marked by dashed lines and points for the flow fronts, mapped by HVO field crews. As of 12:30 p.m. today, the most downslope flow is within 4 miles (6 kilometers) of the Daniel K. Inouye Highway (Saddle Road).
