The Waikupanaha and Kupapau ocean entries remain active. Surface flows over the past week have broadened the Kupapau delta, which now extends along the coastline for about 0.6 miles. A deflation/inflation (DI) event at Kilauea’s summit (ongoing as of Thursday, April 2) has begun to disrupt the supply of lava through the TEB tube system. 

At Kilauea’s summit, the vent within Halemaumau Crater continues to emit elevated amounts of sulfur dioxide gas, resulting in high concentrations of sulfur dioxide downwind. The active lava pond in the vent, visible only with a thermal camera, remains more than 100 yards below the vent rim.
