Volcano Watch: Kilauea activity update

(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 series of deflation-inflation cycles (DI events) over the past week disrupted the supply of lava through the tube system. 

As a result, surface flows on the pali have been largely absent over the past week, though a few small breakouts were reported. 

Faint glow above the vent at Kilauea’s summit remains visible at night, and an incandescent hole is visible on the floor of the vent after dark in the Halemaumau Overlook webcam. Lava has not yet reappeared. Volcanic gas emissions remain elevated, resulting in high concentrations of sulfur dioxide downwind. 

Three earthquakes beneath Hawaii Island were reported felt this past week. 

* A magnitude-1.8 earthquake occurred at 8:34 p.m. Friday, Aug. 14 and was located 4 miles WNW of Pohakuloa at a depth of 10 miles. 

* A magnitude-2.9 earthquake at 4:18 a.m. Saturday, Aug. 15, was located 3 miles N of Kaena Point at a depth of 6 miles.

* A magnitude-2.4 earthquake at 4:29 p.m. Sunday, Aug. 16, was located 1.2 miles ENE of Puulena Crater at a depth of less than 0.6 miles.
