Recent Updates from the U.S. Geological Survey Volcano Hazards Program http://volcanoes.usgs.gov/ U.S. Geological Survey Volcano Hazards Program Thu, 09 Feb 2012 20:09:45 +0000 Activity Summary for past 24 hours: Overall eruptive activity was low. DI inflation and the rising of the summit lava lake started this morning. Within Pu`u `O`o Crater, glow was visible from sources on the northeast and southeast edges of the floor. Surface flows southeast of Pu`u `O`o were mapped by HVO geologists yesterday but there were no active surface flows on the pali, coastal plain, or entering the ocean. Seismic tremor levels were low and gas emissions were elevated. Past 24 hours at Kilauea summit: The summit tilt network recorded DI deflation at 8:45 am ...http://volcanoes.usgs.gov/activity/archive/current.php?noticeid=6974http://volcanoes.usgs.gov/activity/archive/current.php?noticeid=697419.421 -155.287WATCHORANGE There was no evidence of ash emissions or elevated surface temperatures in cloudy satellite images over the past day. There have been no indications of explosive ash-producing activity from satellite or from distant seismic, pressure or lightning sensors. It remains possible for intermittent, sudden explosions of blocks and ash to occur at any time, and ash clouds exceeding 20,000 feet above sea level may develop. Such explosions and their associated ash clouds may go undetected in satellite imagery for hours. If a large, explosive, ash-producing event occurs, seismic, infrasound, or ...http://volcanoes.usgs.gov/activity/archive/current.php?noticeid=6973http://volcanoes.usgs.gov/activity/archive/current.php?noticeid=697352.8222 -169.945WATCHORANGE Activity Summary for past 24 hours: Overall eruptive activity was low. DI inflation and the rising of the summit lava lake slowed last night. Within Pu`u `O`o Crater, glow was visible from sources on the northeast and southeast edges of the floor. Surface flows southeast of Pu`u `O`o resumed activity based on satellite imagery but there were no active surface flows on the pali, coastal plain, or entering the ocean. Seismic tremor levels were low and gas emissions were elevated. Past 24 hours at Kilauea summit: The summit tilt network recorded slowing DI inflation and the ...http://volcanoes.usgs.gov/activity/archive/current.php?noticeid=6972http://volcanoes.usgs.gov/activity/archive/current.php?noticeid=697219.421 -155.287WATCHORANGE
