Kilauea is one of the world's most active volcanoes, but it is of the sort that tends to ooze lava more often than it explodes. Until March 19, 2008, the last explosive eruption from the Halema'uma'u Crater, the summit crater, occurred in 1924. But starting on March 19, a small explosion from the crater rained rock and ash over the summit. The explosion heralded further activity at the summit, including a two to four fold increase in the amount of sulfur dioxide seeping from the volcano. The Hawaiian Volcano Observatory warned on March 28 that sulfur dioxide concentrations in the air downwind from the volcano were likely to be hazardous, particularly to children or those with asthma or other breathing difficulties. Even before the March 19 explosion, elevated sulfur dioxide levels prompted the National Park Service to close part of Crater Rim Drive starting in mid-February.

Kilauea Daily Update issued Mar 11, 2010 08:11 HST Volcano Alert Level WATCH - Aviation Color Code ORANGE
Activity Summary for past 24 hours: The switch to DI inflation yesterday afternoon has not yet resulted in increased activity at the two eruption locations on Kilauea volcano. At the summit, lava was only visible to an infrared camera at low levels in a deep pit inset within the floor of Halema`uma`u Crater but it still produced weak glow that was visible from the Jaggar Museum. At the east rift zone vents, less lava flowed through tubes and fed fewer scattered surface flows on the pali and the coastal plain. Sulfur dioxide emission rates from both summit and east rift zone vents, ... Details...

Kilauea Daily Update issued Mar 10, 2010 07:39 HST Volcano Alert Level WATCH - Aviation Color Code ORANGE
Activity Summary for past 24 hours: DI deflation and subdued activity continued at two locations on Kilauea volcano. At the summit, lava was mostly at low levels in a deep pit inset within the floor of Halema`uma`u Crater, and produced weak glow that was visible from the Jaggar Museum. At the east rift zone vents, less lava flowed through tubes and fed fewer scattered surface flows on the pali and the coastal plain. Sulfur dioxide emission rates from both summit and east rift zone vents, however, remained elevated. Past 24 hours at Kilauea summit: The circulating and ... Details...
