VOG UPDATE
Scientists say reduced sulfur dioxide emissions from Kilauea’s east rift may mean less vog choking the west side of the Big Island.
The Hawaiian Volcano Observatory says that a period of improved air quality in leeward Hawaii has persisted since late spring, as compared with that of the previous six months. This reprieve is coincident with a notable decrease in sulfur dioxide gas emissions measured from east rift eruptive vents.
The HVO says there have been no instances of the S.O.2. levels exceeding the federal health standard of PM2.5 since April 2010.
Scientists say a lull in the lava Ocean Entry in Kalapana may also be contributing to the recent air quality.
