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.

Shishaldin Daily Update issued Sep 2, 2014 11:36 Volcano Alert Level WATCH - Aviation Color Code ORANGE
Low-level seismic activity is continuing but has changed little over the past 24 hours. Elevated surface temperatures in the summit crater observed in satellite data. Web camera images are obscured by clouds. Details...

Kilauea Daily Update issued Sep 2, 2014 08:54 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. Summit tilt had little net change over the past day, and the lava lake level fluctuated slightly. At the middle East Rift Zone, the front of the June 27th flow continued spilling into a ground crack, and surface breakouts also remain active closer to Puʻu ʻŌʻō. June 27th Lava Flow Observations: The June 27th lava flow remains active. At mid-day yesterday, the most distant active lava was 12.6 km (~7.8 miles) from the vent, ... Details...

Yellowstone Monthly Update issued Sep 2, 2014 11:04 Volcano Alert Level NORMAL - Aviation Color Code GREEN
Seismicity During August 2014, the University of Utah Seismograph Stations, responsible for the operation and analysis of the Yellowstone Seismic Network, reports 207 earthquakes were located in the Yellowstone National Park (YNP) region. The largest event was a small earthquake of magnitude 2.2 on August 6, at 5:55 AM MDT, located about 15 miles southwest of Mammoth, YNP. The August earthquake sequences are described below. 1) The largest series of earthquakes (74 ranging in magnitude from -0.9 to 2.0) occurred August 18 - 21, just outside of YNP, about 6 miles north of West ...

Cleveland Daily Update issued Sep 1, 2014 12:39 Volcano Alert Level ADVISORY - Aviation Color Code YELLOW
A thermal feature was observed at the summit of Cleveland Volcano in several clear satellite images over the past 24 hours. Clear web camera views of the volcano today showed nothing unusual. AVO has received no reports of activity over the past 24 hours. Details...

Shishaldin Daily Update issued Sep 1, 2014 12:39 Volcano Alert Level WATCH - Aviation Color Code ORANGE
Low-level seismic activity is continuing but has changed little over the past 24 hours. Nothing unusual observed in mostly clear satellite and web camera images over the past 24 hours. Uncertain if low-level eruptive activity in the crater is continuing. Details...

Kilauea Daily Update issued Sep 1, 2014 09:13 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 switched to slow deflation at the summit, and the lava lake level was relatively stable. At the middle East Rift Zone, the front of the June 27th flow spilled into another ground crack, and surface breakouts also remain active closer to Puʻu ʻŌʻō. June 27th Lava Flow Observations: The June 27th lava flow remains active. During a Civil Defense flight this morning, the farthest part of the flow, which had ... Details...
