Volcano Watch: Kilauea activity update for week of July 8

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

Surface flows reached the base of Pulama pali over the past week and began following the eastern edge of the flows erupted a few months ago. As of Thursday, July 15, the surface activity had reached to within less than 500 m (550 yards) from the end of Highway 130.

Repeated deflation/inflation (DI) events at Kilauea’s summit, ongoing for the last several days, may cause the surface flows on the coastal flat to likewise stall and restart repeatedly.

At Kilauea’s summit, a circulating lava pond deep in the collapse pit within the floor of Halemaumau Crater was visible via the Webcam throughout the past week. The baseline lava level was punctuated sporadically by short-lived lava-level increases. Volcanic gas emissions remain elevated, resulting in high concentrations of sulfur dioxide downwind.

Three earthquakes beneath Hawaii Island were reported felt during the past week.

A magnitude-3.0 earthquake occurred at 8:58 p.m. Sunday, July 11 and was located 14 km (9 miles) northeast of Hawi at a depth of 39 km (24 miles).

A magnitude-3.1 earthquake occurred at 6:37 a.m. Monday, July 12, and was located 10 km (6 miles) northwest of Kaena Point at a depth of 10 km (6 miles).

A magnitude-3.0 earthquake occurred at 7:22 p.m. Tuesday, July 13, and was located 5 km (3 miles) southeast of Puu Oo Crater at a depth of 9 km (6 miles).
