From WATCH to WARNING and back

_{From September 4, 2014, to March 25, 2015, USGS Hawaiian Volcano Observatory scientists raised the Volcano Alert Level for Kīlauea from WATCH to WARNING as the June 27th lava flow advanced toward Pāhoa and posed an imminent hazard and threat to nearby communities and infrastructure. Shown here on September 12, the leading edge of the lava flow (marked by dense smoke, middle right) burned through thick forest less than 200 m (220 yds) from the boundary of Kahoe Homesteads (lower left).
