April 10, 2008 Press Release - Halema`uma`u Vent Explodes a Second Time

Current SO2 Levels and Wind Direction in the Hawai`i Volcanoes National Park (website operated by the National Park Service)

Halema`uma`u gas plume

This was the view from the Mauna Loa Strip Road in Hawai`i Volcanoes National Park at 7 a.m. this morning. Stagnant surface winds, combined with higher elevation winds from the southwest, caused the plume to rise straight up and then shear off to the northeast.
