NEWS BRIEF

The USGS Hawaiian Volcano Observatory issued a new Volcanic Activity Notice on Friday at 3:59 p.m.

Between September 17 and 19, the June 27th flow continued to advance northeastward at a slower average rate of 190 m/day (625 ft/day). By midday on September 19, the flow had advanced approximately 16.3 km (10.1 mi) straight-line distance from the vent across the vacant, forested northwest portion of Kaohe Homesteads. Using the most recent rate of advancement of 190 m/day (625 ft/day) between September 17 and 19, we project that lava could flow from its current location to Apa`a St. in 13 days, to the Pāhoa Village Road (government road) in Pāhoa within 18 days, and highway 130 in 21 days. These estimates will be updated after our next overflight to be scheduled early next week.
