Volcano Watch: Kilauea activity update for week of Aug. 19

(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, where it enters the water at the tip of the delta. 

This has been the only lava visible on the flow field since surface flows stagnated a few weeks ago. 

Faint glow above the vent at Kilauea’s summit remains visible at night, and an incandescent hole has been seen on the floor of the vent after dark in the Halemaumau Overlook Webcam. 

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-2.5 earthquake occurred at 3:24 a.m. Sunday, Aug. 23 and was located 7 miles southwest of Waikii at a depth of  24 miles.
