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.

Recent Volcano Observatory Activity Reports from USGS


Cascade Range Weekly Update issued Apr 18, 2014 13:28 Volcano Alert Level NORMAL - Aviation Color Code GREEN
Activity Update: All volcanoes in the Cascade Range of Oregon and Washington are at normal levels of background seismicity. These include Mount Baker, Glacier Peak, Mount Rainier, Mount St. Helens, and Mount Adams in Washington State; and Mount Hood, Mount Jefferson, Three Sisters, Newberry, and Crater Lake in Oregon. Recent Observations: A swarm of approximately 10 very small earthquakes occurred ~4km south of the summit of Mount Hood between April 15th and 16th. Swarms like this typically occur several times per year near Mount Hood and are consistent with usual background activity. Details...

Cleveland Weekly Update issued Apr 18, 2014 12:08 Volcano Alert Level ADVISORY - Aviation Color Code YELLOW
No activity observed in satellite data during clear periods over the past week. Details...

Veniaminof Weekly Update issued Apr 18, 2014 12:08 Volcano Alert Level ADVISORY - Aviation Color Code YELLOW
Seismicity over the past weeks remains slightly above background. Web camera images during periods of clear weather show typical steaming from the previously active cone. Satellite images show weakly elevated surface temperatures consistent with cooling of the 2013 lava flows. Details...

Shishaldin Weekly Update issued Apr 18, 2014 12:08 Volcano Alert Level WATCH - Aviation Color Code ORANGE
Elevated surface temperatures consistent with low-level eruptive activity in the summit crater were observed in satellite data earlier in the week during periods of clear weather. Small explosions continue to be observed in seismic data, but no ash emissions have been detected. Minor steaming observed in web camera images during clear periods over the past week. Details...

Kilauea Daily Update issued Apr 18, 2014 07:43 Volcano Alert Level WATCH - Aviation Color Code ORANGE
Activity Summary: The eruption continued at the summit and within the east rift zone with no significant changes. The summit tiltmeter network recorded continued DI inflationary tilt and the level of the circulating summit lava lake continued to rise. At the middle east rift zone, Pu`u `O`o vents continued feeding the Kahauale`a 2 lava flow whose distal end showed signs of activity in webcam views. Gas emissions remained elevated. Recent Observations at Kilauea summit: The summit tiltmeters recorded continued DI inflationary tilt (+4.5 microradians over the past 3.5 d). The ... Details...

Pagan Weekly Update issued Apr 18, 2014 09:35 Volcano Alert Level ADVISORY - Aviation Color Code YELLOW
Low-level unrest continued at Pagan Volcano throughout the past week. Seismic activity remains above background. A vapor plume was visible in web camera and satellite images during clear periods this week. This level of unrest is typical of the past several months. Volcanic gas from Pagan may be noticed downwind of the volcano as distinctive sulfurous odors. 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 ... Details...

Cleveland Daily Update issued Apr 17, 2014 12:00 Volcano Alert Level ADVISORY - Aviation Color Code YELLOW
Satellite observations partly obscured by clouds over the past day. No activity observed. Details...

Veniaminof Daily Update issued Apr 17, 2014 12:00 Volcano Alert Level ADVISORY - Aviation Color Code YELLOW
Seismicity over the past day is slightly above background. Web camera images show typical steaming from the previously active cone. No activity observed in satellite images. Details...

Shishaldin Daily Update issued Apr 17, 2014 12:00 Volcano Alert Level WATCH - Aviation Color Code ORANGE
Minor steaming observed in web camera images during clear periods over the past day. Satellite images show no evidence of eruptive activity. No significant changes observed in seismic data. Details...

Kilauea Daily Update issued Apr 17, 2014 07:29 Volcano Alert Level WATCH - Aviation Color Code ORANGE
Activity Summary: The eruption continued at the summit and within the east rift zone with no significant changes. The summit tiltmeter network recorded continued DI inflationary tilt and the level of the circulating summit lava lake continued to rise. At the middle east rift zone, Pu`u `O`o vents continued feeding the Kahauale`a 2 lava flow whose distal end showed renewed signs of activity in webcam views. Gas emissions remained elevated. Recent Observations at Kilauea summit: The summit tiltmeters recorded continued DI inflationary tilt (+4 microradians over the past 2.5 d). ... Details...
