A small lava lake was present deep within the Halemaumau Overlook vent during the past week.

Several deflation/inflation cycles were recorded at the summit throughout the week. The level of the lake fell during the deflation and rose again slightly during the inflation, exposing a lava cascade within the vent when the lake level was low.

Volcanic gas emissions remain elevated, resulting in relatively high concentrations of sulfur dioxide downwind.

Lava also erupted continuously within Puu Oo over the past week, feeding a lava lake perched above the crater floor. The crater floor was 39 m (128 ft) below the east rim of Puu Oo when measured on June 1.

Two vents on the west and southwest crater floor reactivated this week, producing minor flows on the west side of the crater. Small overflows continued to pour over the edges of the perched lava lake.

No lava is erupting outside the crater.

One earthquake beneath Hawaii Island was reported felt this past week.

A magnitude-3.4 earthquake occurred at 12:49 p.m. Tuesday, June 7 and was located 6 km (4 mi) south of Kalapana at a depth of 39 km (24 mi).
