Volcano Watch: Kilauea activity update for week of April 8

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

On Kilauea’s east rift zone, breakouts along the east margin of the Thanksgiving Eve Breakout (TEB) flow remain active on the Pulama pali. The active flow front was just a few hundred yards from rejoining the main TEB flow field on the coastal plain Thursday, April 15.

If lava supply to these flows continues, they are expected to migrate south along the east margin of the TEB flow field, near the public viewing area. The flows may also stall before reaching the coast due to ongoing lava supply fluctuations.

At Kilauea’s summit, a ponded, circulating lava surface deep within the collapse pit inset within the floor of Halemaumau Crater was visible via Webcam during much of 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. The magnitude-3.8 earthquake occurred at 7:37 a.m. Wednesday, April 14 and was located 4 km (2 miles) west of Pahala, at a depth of 38.2 km (23.7 miles),
