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.

Pagan Weekly Update issued Aug 1, 2014 07:37 Volcano Alert Level ADVISORY - Aviation Color Code YELLOW
Low-level unrest continued at Pagan Volcano throughout the past week. A steam and gas plume was visible in web camera and satellite images during periods of clear weather. Low-level seismic activity is ongoing. Volcanic gas from Pagan may be noticed downwind of the volcano as a distinctive sulfurous odor. Additional information about volcanic gas and vog can be found on the web at this address: http://hvo.wr.usgs.gov/hazards/FAQ_SO2-Vog-Ash/main.html Access to the island may be restricted by the CNMI government. Contact the EMO for the latest information. Details...

Kilauea Daily Update issued Jul 31, 2014 08:50 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. There was no significant ground tilt at the summit, and the lava lake level was relatively steady. At the middle East Rift Zone, small lava ponds were present in Puʻu ʻŌʻō, and the June 27th flow continued to advance to the northeast. Recent Summit Observations: There was no significant ground tilt at Kīlauea's summit over the past day, and the lava lake level was relatively steady, hovering around 35 m below the ... Details...
