Volcano Watch: Activity update for week of Dec. 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 two locations — Waikupanaha and west Waikupanaha. Small surface flows have been sporadically active on the coastal plain for the last several weeks.

In the past week, these surface flows were scattered mostly over a broad area just inland from the shoreline more than 1 km to the west of the Hawaii County lava viewing trail.

Glow above the vent at Kilauea’s summit has been visible at night from the Jaggar Museum. Incandescent openings, sometimes yielding bursts of spatter, were visible on the floor of the vent cavity throughout the week, as recorded by the Webcam perched on the rim of Halemaumau Crater.

Volcanic gas emissions remain elevated, resulting in high concentrations of sulfur dioxide downwind.

No earthquakes beneath Hawaii Island were reported felt for the second week.
