Lava fountains in Mokuaweoweo from the west rim.

On Kilauea’s east rift zone, small breakouts remain active above Pulama pali and were visible from Kalapana by the beginning of the week. Despite the continued activity, the overall vigor of the surface flows seems lower than usual.

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

Two earthquakes beneath Hawaii Island, both southwest of Waimea, were reported felt during the past week.

A magnitude-2.1 earthquake occurred at 3:13 a.m. Monday, March 29 and was located 6 km (4 miles) southwest of Waimea, at a depth of 8 km (5 miles).

A magnitude-2.4 earthquake occurred at 1:59 p.m. Tuesday, March 30, and was located 7 km (4 miles) southwest of Waimea, at a depth of 2 km (2 miles).
