Volcano Watch: Kilauea activity update for week of June 3

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

Over the past week, activity on the east rift zone flow field remains focused on the construction of low shields. This activity was located well above the Pulama pali, over the breakout point of the Quarry flow.

Weak activity continues along the Quarry flow itself from the top of the pali to the coastal plain. In addition to that lava erupting and flowing through the TEB and Quarry flow tube systems, lava is also erupting from two vents within Puu Oo. These vents are slowly filling Puu Oo’s crater, and the Webcam on Puu Oo has been providing spectacular views both day and night.

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 continues to rise slowly and was punctuated a few times by short-lived lava-level increases that brought the lava surface to its highest level yet recorded. Volcanic gas emissions remain elevated, resulting in high concentrations of sulfur dioxide downwind.

No earthquakes beneath Hawaii Island were reported felt during the past week.
