Volcano Watch: Kilauea activity update for week of Feb. 11

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

Surface flows have been active within and adjacent to the Royal Gardens subdivision. While some of these flows have been located on the pali, most of the activity has been focused on the coastal plain within about 1 km (3,300 ft) of the base of the pali.

Lava flows remained active despite back-to-back deflation/inflation (DI) events during the week at Kilauea’s summit, though variations in surface activity did occur in response to the DI events.

At Kilauea’s summit, a spattering and roiling lava surface, deep within the collapse pit inset within the floor of Halemaumau Crater, was visible via Webcam. The depth to the lava surface varied in response to the DI events, lowering during the deflation phase and rising slightly during inflation.

Overprinted on these broader changes were periods of repeated and relatively rapid rise and fall of the lava surface. Volcanic gas emissions remain elevated, resulting in high concentrations of sulfur dioxide downwind.

No earthquakes beneath Hawaii Island were reported felt during the past week.
