Pyroclastic flow

Lava dream meaning. Dream about lava pouring out from cracks. Running away from fiery lava. Lava cooled down. Biblical meaning of lava in dream. Falling into lava. Lava under you feet. Lava floods. Escaping lava. Lava not burning.

On May 18th, 1980, thirty years ago today, at 8:32 a.m., the ground shook beneath Mount St. Helens in Washington state as a magnitude 5.1 earthquake struck, setting off one of the largest landslides in recorded history - the entire north slope of the volcano slid away. As the land moved, it exposed the superheated core of the volcano setting off gigantic explosions and eruptions of steam, ash and rock debris. The blast was heard hundreds of miles away, the pressure wave flattened entire…

A major eruption started at the Indonesian Sinabung volcano at 23:42 UTC on March 1, 2021, ejecting ash up to 12.2 km (40 000 feet) above sea level.

Everybody knows that volcanoes are super-dangerous, and that the only person who can stop one is Tommy Lee Jones. Here's how you can be killed by one.

​In this recent photo taken at Puʻu ʻŌʻō Crater​ in Hawaii, we can see ​that ​elemental sulfur vapor escaping from ​the fumarole ​has cooled to form yellow-colored crystals around the margins of the crack. Fumaroles are vents from which volcanic gas escapes into the atmosphere. Fumaroles may occur along tiny cracks or long fissures, in chaotic clusters or fields, and on the surfaces of lava flows and thick deposits of pyroclastic flows. They may persist for decades or centuries if they are…

Pyroclastic density currents (PDCs) are perhaps the most hazardous events to local areas during explosive volcanic eruptions.
