Pyroclastic flow will destroy nearly everything in its path. With rock fragments ranging in size from ash to boulders traveling across the ground at speeds greater than 80 km per hour, pyroclastic flows knock down, shatter, bury or carry away nearly all objects and structures in their way. The extreme temperatures of rocks and gas inside pyroclastic flows, between 200°C and 700°C, can cause combustible material to burn, especially petroleum products, wood, vegetation, and houses. -- Samuel…
▶ Extreme Pyroclastic Flows At Sinabung Volcano, Indonesia 21st Jan 2014 - Mount Sinabung is a Pleistocene-to-Holocene stratovolcano of andesite and dacite in the Karo plateau of Karo Regency, North Sumatra, Indonesia, 25 miles from Lake Toba supervolcano.
Río Lagunillas, former location of Amero. An explosive eruption from Ruiz's summit crater on 11/13/1985 generated an eruption column and sent a series of pyroclastic flows down the mountain. 23,000 people were killed. This event was the 2nd-deadliest-volcanic disaster in the 20th century, being surpassed by the 1902 eruption of Mt. Pelée, and the 4th-deadliest-volcanic eruption in recorded history.
