Volcano Watch: Kilauea activity update for week of Sept. 3

(Activity updates are written by scientists at the U.S. Geological Survey’s Hawaiian Volcano Observatory.) 

Lava continues to erupt from the TEB vent on Kilauea’s east rift zone and flow through tubes to the ocean at Waikupanaha. A lava breakout from the tube near the top of the Royal Gardens subdivision has been active since Sept. 2. 

The flow has progressed downslope only a short distance, its terminus burning forested kipuka along the eastern edge of the TEB flow.

Faint glow above the vent at Kilauea’s summit has been visible at night, though its brightness, as of Sept. 10, had diminished compared to its appearance earlier in the week. Volcanic gas emissions remain elevated, resulting in high concentrations of sulfur dioxide downwind. 

One earthquake beneath Hawaii Island was reported felt this past week. 

A magnitude-3.3 earthquake occurred at 7:22 p.m. Wednesday, Sept. 9 and was located 5 miles southeast of Hookena at a depth of 7 miles.
