An eruption column or eruption plume is a cloud of super-heated ash and tephra suspended in gases emitted during an explosive volcanic eruption. The volcanic materials form a vertical column or plume that may rise many kilometers into the air above the vent of the volcano.
There are many instances of damage to jet aircraft as a result of an ash encounter. On 24 June 1982, a British Airways Boeing 747-236B flew through the ash cloud from the eruption of Mount Galunggung, Indonesia resulting in the failure of all four engines. The plane descended 24,000 feet (7,300 m) in 16 minutes before the engines restarted ...
This eruption lasted eight days, from 7–15 June of that year, with an ash cloud that would have required additional days to dissipate, [76] and resulted in worldwide abnormal weather and decrease in global temperature over the next few years. However, the second phase of Eyjafjallajökull's eruption lasted longer than that of Mount Pinatubo.
A volcanic eruption is one of the most powerful forces in nature, a seemingly unstoppable phenomenon that can have far-reaching impacts far beyond the area surrounding the volcano itself. When a ...
The spectacular bolts of lightning streak through the ash cloud as red hot molten lava slowly seeps towards villages below that have since been engulfed by the liquid fire as if the gates of hell ...
The ash cloud from the 1991 eruption of Mount Pinatubo in the Philippines traveled more than 5,000 miles and damaged more than 20 airplanes, USGS reported. The incident in 1989, among others ...
Pyroclastic flows sweep down the flanks of Mayon Volcano, Philippines, in 2018. A pyroclastic flow (also known as a pyroclastic density current or a pyroclastic cloud) [1] is a fast-moving current of hot gas and volcanic matter (collectively known as tephra) that flows along the ground away from a volcano at average speeds of 100 km/h (30 m/s; 60 mph) but is capable of reaching speeds up to ...
The Volcanic Ash Advisory Center (VAAC) in Tokyo has warned that “explosive activity” is continuing. The eruption of the Shiveluch volcano reportedly caused by 7.0-magnitude earthquake on the ...
