Mount St. Helens Eruption, May 18, 1980. The complete Gary Rosenquist sequence in HD.

Ғылым және технология

On Saturday, May 17, 1980, Gary Rosenquist, along with friends William Dilley, Joel Harvey and his wife Linda, arrived at a log landing on Forest Road 100, eight miles northeast of Mount St. Helens. Nearby, and having arrived earlier that afternoon, was UW graduate student Keith Ronnholm. Together, Rosenquist, Dilly, and the Harveys camped overnight.
The next morning, May 18, 1980, dawned crystal clear. Rosenquist fires off a frame of Mount St. Helens basked in the alpenglow of a dawn sunrise. At 8:27, he fires off another.
Five minutes later, William Dilley, watching the peak through binoculars, screams, "There she goes!" as a 5.1 magnitude quake sends a mile-wide slab of rock and ice cascading down Mount St. Helens' north flank. 26 seconds after the earthquake, the mass descends 2,300 feet (700 meters), and Gary Rosenquist begins firing off a rapid succession of 21 irregularly-timed photographs over the course of the next 36 seconds. His images became historic.
Until now, no attempt has been made to compile a seamless morph of those historic images and do it in a fashion that isn't overly embellished as some documentaries have done.
Using the latest in AI software and the latest pixel processing algorithms, all 21 images of Rosenquist's historic sequence have been seamlessly morphed into a fluid motion video. Due to the fact that some of Rosenquist's photos are irregularly timed (with gaps of up to nearly three seconds between frames), there are some portions that had to be synthesized. This appears as a jumpy motion of the blast cloud later in the sequence. This is Ver. 1, and a future release of this will attempt to remedy those anomalies.
All images (C) 1980 Gary Rosenquist. Used here under Fair Use.

    Simply amazing. I've heard the projectiles you see emanating from the smoke during the explosion described as "house size." Ferociousness of nature at its peak.

    Very large house-sized, in fact some of them were close to the size of the present-day observatory building at Johnston Ridge. The sheer forces within that explosion to hurl projectiles that large, at such great distances (and at such a great height, since they were close to 9,600 feet in elevation), just boggles my mind.

    My mom was on a field trip in Seattle during her 18th birthday when this erupted and I grew up hearing the stories about how it was as if it began to snow ash and eventually day became night from how much the sun was blocked out by the ash cloud. Crazy.

    I've seen the original 'time-lapse' clip many times, but this one is the clearest I've seen so far. It's clear enough for me to see something I'd read about in a text-book chapter on the Mt St Helens flank collapse, but had not properly understood, namely that the collapse didn't happen all at once. I'd read, and seen an illustration, showing that the collapse happened in three stages, with each successive stage taking another significant chunk out of the cone. To be honest, I thought it had all happened too fast for the human eye to differentiate between the stages, but, watching this new time lapse carefully, I could see each section collapse as it occurred, despite the lateral volcanic blast starting as the first chunk of the mountain collapsed.

    My Dad calls the day of this eruption the day my maternal grandma accepted him at last. First he got chased out of the house by grandma waving a cast iron skillet and screaming in Swedish at him. Second, he rolled his car and ended up at the hospital with wrenched ligaments in both knees. Third, my mom and my grandma picked him up from the hospital and took him back home. Finally, grandpa did a more through work up on him and declared him healthy with bruised kneecaps and mild whiplash. Six months later, he and mom were married. Mom was given that cast iron skillet, which was later given to my older sister on her wedding day. No one is sure of the skillet’s actual age. Rumors claim it was forged during the 1400s, which I highly doubt. It’s probably not the same skillet, but a skillet traveled to America with my great great great grandma, most likely during early to mid 1800s. Before the eruption began, my grandpa went and got his clinic stocked with extra supplies and put out word to mask up before going out, even if there’s no ash fall in the area during and after the eruption. There were a number cases of Ash Lung after the eruption. Ash Lung is the result of breathing in ash. Ash is actually glass that’s been ground into dust. Breathing that in is going to cut up your lungs. The medical term is pneumonoultramicroscopicsilicovolcanoconiosis. Long word. Even us medical professionals won’t attempt to pronounce the word. We use the term Ash Lung instead.
