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 Sep 30, 2014 08:52 Volcano Alert Level WARNING - Aviation Color Code ORANGE
Activity Summary: Kīlauea continued to erupt at its summit and within the East Rift Zone, and gas emissions remained elevated. Inflationary ground tilt and a rise in lava level were recorded at the summit over the past day. At the middle East Rift Zone, the leading edge of the June 27th lava flow remains stalled, although scattered breakouts of lava are present near the lava flow front and at other places between the flow front and Puʻu ʻŌʻō. June 27th Lava Flow Observations: The June 27th lava flow remains active. An HVO overflight on Monday ... Details...

Kilauea VAN/VONA issued Sep 29, 2014 17:34 Volcano Alert Level WARNING - Aviation Color Code ORANGE
The June 27th flow front remains stalled 2.3 km (1.4 miles) upslope from Apa`a St. and 3.3 km (2.1 mi) from Pāhoa Village Road. Two slow-moving lobes behind the stalled front have advanced northeast 65 and 80 m (215 and 260 ft) since September 26; the nearest lobe is about 125 m (410 ft) behind the stalled front. Lava continues to break out of the tube about 8 km (5 mi) behind the flow front near where lava entered a crack system on August 18. The stalled leading edge of the flow is approximately 16.4 km (10.2 miles) straight-line distance from the vent. Because the flows near the ... Details...
