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 Aug 27, 2014 09:23 Volcano Alert Level WATCH - Aviation Color Code ORANGE
Activity Summary: Kīlauea continued to erupt at its summit and within the East Rift Zone, and gas emissions remained elevated. Slow inflation continued, and the lava lake level was 55-60 m below the Overlook crater rim. At the middle East Rift Zone, the June 27th flow continued to advance towards the northeast and was 3 km from the Forest Reserve boundary. Recent Summit Observations: Slow inflation at Kīlauea's summit, which started on August 24, continued over the past day. The lava lake, however, remained at a relatively steady level roughly 55-60 m below the ... Details...
