Volcano Watch: Kilauea activity update for week of May 6

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

Breakouts, scattered from the top of the Pulama pali to the coast along the new Quarry flow, were active throughout the past week, and lava continues to enter the water at the Ki ocean entry.

The ocean entry has become better established and the surface flows near the end of Highway 130 have slowed dramatically. As of this writing (Thursday, May 13), a few small breakouts continue near the end of the road, but most of the surface activity is found farther upslope.

At Kilauea’s summit, a ponded, circulating lava surface deep in the collapse pit within the floor of Halemaumau Crater was visible via Webcam throughout the past week. The lava surface remained relatively steady, showing little variation in depth below the rim of the vent. Volcanic gas emissions remain elevated, resulting in high concentrations of sulfur dioxide downwind.

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

A magnitude-2.3 earthquake occurred at 12:21 p.m. Saturday, May 8 and was located 1 km (1 mile) southeast of Paauilo, at a depth of 13 km (8 miles).

A magnitude-2.4 earthquake occurred at 6:00 a.m. Wednesday, May 12 and was located 10 km (6 miles) southeast of Waikii, at a depth of 20 km (12 miles).
