Volcano Watch: Kilauea activity update for week of March 17

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

On Kilauea’s east rift zone, small breakouts were active well above the pali, about 1 km (0.6 mile) above Royal Gardens subdivision, through the week. There are no active flows on the face of the pali, on the coastal plain, or in the National Park.

At Kilauea’s summit, a spattering and roiling lava surface deep within the collapse pit inset within the floor of Halemaumau Crater was occasionally visible via Webcam during the past week. Volcanic gas emissions remain elevated, resulting in high concentrations of sulfur dioxide downwind.

One earthquake beneath Hawaii Island was reported felt during the past week.

A magnitude-2.9 earthquake occurred at 1:11 a.m. Wednesday, March 24 and was 15 km (9 miles) west of Pahala, at a depth of 3 km (2 miles).
