Current Volcano Alert Level: WARNING
Current Aviation Color Code: ORANGE

Kīlauea Lower East Rift Zone

This morning, eruptive activity remained concentrated at fissure 17, with intermittent lava spattering at fissure 18. Earlier this morning, a new fissure (20) located near fissure 18 produced two small pads of lava. The 'a'ā flow spreading from fissure 17 advanced about 380 m (1,250 ft) since 2:30 p.m. HST yesterday. The advance of the flow has slowed significantly since yesterday afternoon. At 6:45 a.m. the flow was nearly 2.5 km (1.5 mi) in length.

Volcanic gas emissions remain elevated throughout the area downwind of the fissures. 

Magma continues to be supplied to the lower East Rift Zone as indicated by the continued northwest displacement of a GPS monitoring station. Elevated earthquake activity continues, but earthquake locations have not moved farther downrift in the past couple of days.
