Volcano Watch: Kilauea activity update for week of Oct. 22

(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. Surface flows were sporadically active at the end of the Kalapana access road adjacent to the county lava viewing area trail at least through Thursday (the date of this writing).
active surface flows were scattered over a broad area extending up to several hundred yards to the west of the end of the road. Relatively bright glow has been visible at night in the Puu Oo crater from a new or enlarged vent on the crater floor.
Very faint glow above the vent at Kilauea’s summit has been visible at night, but the lava surface has receded below the view from the webcam on the rim of Halemaumau above the vent and is not currently visible. Volcanic gas emissions remain elevated, resulting in high concentrations of sulfur dioxide downwind.
Two earthquakes beneath HawaiiIsland were reported felt this past week.
A magnitude-4.8 earthquake occurred at 11:13 p.m. Thursday, Oct. 22, 2009, and was located 4 miles southeast of Loihi Volcano at a depth of 10 miles.
A magnitude-2.6 earthquake occurred at 10:13 p.m. Tuesday, Oct. 27, and was located 5 miles southwest of Waikii at a depth of 18 miles.
