November 29, 2022 — Mauna Loa Eruption Map

The Northeast Rift Zone eruption of Mauna Loa has continued into its second full day. At this time two fissures are active, sending lava flows in multiple directions. Overnight satellite views allowed USGS analysts to accurately map some of the most active flows, displayed in red here. Further downslope progression of the flows this morning is marked by dashed lines and points for the flow fronts at 12:00 p.m. today. As of that time, the most downslope flow is within 5.5 miles (9 kilometers) of Saddle Road.
