Alaska announces high alert level after volcanic eruption

Alaska announces high alert level after volcanic eruptionA huge volcanic eruption took place in Alaska’s Bogoslof Island that has issued high alert level. The erupted cloud raised up to minimum 35,000 ft. and 45,000 ft. maximum, according to the observatory. Jeffrey Freymueller, a professor at Geophysical Institute at the University of Alaska said, “We observed the red color code this afternoon because of numerous lightning detections and increased seismic signals.” He further added, “Lightning in the Aleutians is mostly happened because of volcanic plumes, as the meteorological conditions for lightning are not common.”

According to the survey conducted by United States Geological, “Ash and aircraft never mix together as volcanic ash is abrasive. It melts at jet engine temperatures and even leads to failure of the engine.” The eruption Eyjafjallajokull volcano that took place in 2010 caused cancellation of all the flights around entire Europe for six days.

AVO scientists captured the images of the eruption from nearby Unalaska Island for around 14 minutes after the eruption started. The images showed a large white-gray mushroom cloud from over the site. According to AVO, ash fallout took place on the west of the site. Observatory revealed the report saying Bogoslof Volcano remains at a heightened state of unrest and in an unpredictable condition. Additional explosions producing high-altitude volcanic clouds could occur at any time, they further added.

 

They issued a warning that continuous low-level activity could pose a hazard in the immediate vicinity of the volcano. The volcano that took place in early 2017 significantly changes the shape and coastline of the island and the land mass increased by 3 times in size between early 2015 and January of this year. The documentation revealed that there were eight eruption events at Bogoslof. The most recent one took place in 1992. Last eruption events lasted from weeks to months, according to AVO. The latest eruption sequence started in December 2016.
