VolcanoesNOAAWatch Volcanoes Headlines


Volcanic Ash from Iceland

Ash from the Eyjafjallajokull volcano continues to spew ash into the atmosphere up to 16,000 feet. The majority of the ash is forecast over the northern Atlantic. Air Travel over much of Europe has resumed with more than 80 percent of Europe free of airspace restrictions along with most airspace over the United Kingdom. Additional information is available from the London Volcanic Ash Advisory Center (VAAC). Details...

Redoubt Volcano in Alaska - Color Code Yellow : Alert Level Advisory

The Alaska Volcano Observatory has lowered the aviation color code to Yellow and the Alert Level to Advisory based on significantly diminished dome growth over the past few weeks. Seismicity is still slightly above background. Details...

Alaska Okmok Volcano

The eruption of Okmok Volcano continues. Currently, seismicity consists of episodic pulses occasionally grading into continuous volcanic tremor. Recent satellite data show plumes of steam and/or ash drifting E/SE within 50 km of Okmok at between 20,000 and 30,000 feet above sea level. Stronger explosive activity could resume at any time with little or no warning. Details...

New Federal Plan to Deal with Volcanic Ash

Federal agencies involved with aviation, volcanoes and weather have created a new way to work together to track volcanic ash plumes and report the risks to the aviation community and keep air travelers out of harmís way. Volcanic ash can cause aircraft engines to fail or damage navigational instruments. The main goal is to eliminate encounters with ash that could degrade the in-flight safety of aircrews and passengers. Details...

Volcanic Ash Advisories

Eruption of volcanoes are monitored by NOAA with Volcanic Ash Advisories issued to keep aviators informed of volcanic hazards. The Anchorage Alaska Volcanic Ash Advisory Center and Washington Volcanic Ash Advisory Center issue advisories for volcanoes in their respective areas of responsibility. Details...
