Matches in DBpedia 2014 for { ?s ?p Pavlof Volcano is a stratovolcano of the Aleutian Range on the Alaska Peninsula. It has been one of the most active in the United States since 1980, with eruptions recorded in 1980, 1981, 1983, 1986–1988, 1996–1997, August 15, 2007 to September 13, and May 13, 2013 to August 8, 2013. The Alaska Volcano Observatory reports on Pavlof Aviation Color Code levels and Volcano Alert levels on a daily basis. With a threat score of 95, the threat from future eruptions is considered to be high; much of this threat comes from the possibility of disruption of nearby air routes by large releases of ash. The mountain currently has basic real-time monitoring, but the USGS would like to improve instrumentation at the site. The mountain shares a name with the nearby Pavlof Sister, which last erupted in 1786.The first recorded ascent of Pavlof Volcano was on June 27, 1928 by T. A. Jagger, J. Gardiner, O. P. McKinley, P. A. Yatchmenoff, R. H. Stewart, although "speculation surrounds this ascent, which was recounted in National Geographic." Due to the straightforward nature of the climb, an earlier unrecorded ascent may have occurred. The second ascent was in June 1950 by T. P. Bank.The main challenge of climbing this peak is its remoteness and the consequent difficulty of access. The peak is a 30 mi (48 km) journey from the north side of Cold Bay. The climb itself is a straightforward snow climb, and the ski descent is recommended.After its eruption in 1996, the volcano entered a period of dormancy, the longest it had been dormant since records of its eruptions have been kept. This period ended on August 15, 2007, with the start of a new eruption involving seismic disturbances and a "vigorous eruption of lava." Scientists said that the volcano "could be working toward a massive eruption that could affect air travel but was not expected to threaten any of the towns in the area." The eruption ended on September 13. The volcano erupted again on May 13, 2013, but activity had greatly diminished by July 3, 2013 and on August 8, 2013 the Current Volcano Alert Level was reduced to NORMAL and the Current Aviation Color Code reduced to GREEN.. }
