You’ve seen the clip. A massive gray wall of ash rolls over a ridge, swallowing everything in its path. It’s grainy, shaky, and feels like something out of a low-budget horror movie from the 80s. But it isn't a movie. It's the volcano eruption video mt st helens that defines the deadliest volcanic event in U.S. history.
May 18, 1980, started as a quiet Sunday morning. Then, at 8:32 a.m., a 5.1 magnitude earthquake shook the ground. The mountain’s north face literally fell off.
The Footage That Shouldn't Exist
Most people think there’s a single "video" of the mountain exploding. Honestly, that’s not quite right. What we usually see is a series of still photos stitched together. These were taken by Gary Rosenquist. He was camping at Bear Meadow, about 11 miles away.
He didn't have a video camera. He had a 35mm film camera.
Rosenquist snapped a sequence of photos so fast it created a proto-video of the landslide and the subsequent lateral blast. You can see the mountain ripple. It looks like liquid. That’s because the pressure "uncorked" the volcano. Imagine shaking a soda bottle for two months and then suddenly ripping the side off with a chainsaw. That’s what happened to Mount St. Helens.
Dave Crockett’s "Journey Into Hell"
If you want the most visceral volcano eruption video mt st helens experience, you have to look for the Dave Crockett footage. Crockett was a photographer for KOMO-TV. He was on the mountain that morning because he had a "hunch."

He ended up trapped in the blast zone.
His video is terrifying. It isn't a wide shot of a mountain; it’s a first-person view of the world turning black. You hear him breathing heavily, choking on ash. At one point, he says to his camera, "I'm walking toward the only light I can see... I honest to God believe I'm dead."
The screen goes dark. You can hear the sound of the mudflows—lahars—roaring like a freight train. He survived, miraculously, but his camera captured the exact moment a forest was erased.
The Photographers Who Didn't Make It
We have to talk about Robert Landsburg. His story is kinda the definition of "dedicated to the craft." Landsburg was within a few miles of the summit. When the explosion happened, he realized he couldn't outrun the cloud.
He didn't panic. Or maybe he did, but he stayed professional.

He kept taking photos as the ash cloud approached. When he knew the end was seconds away, he rewound his film, put the camera in its case, put the case in his backpack, and then laid his body on top of the bag. He wanted to make sure the film survived even if he didn't.
His body was found 17 days later. The film was intact. Those photos are some of the most haunting images ever captured of a natural disaster.
Why the "Video" Looks So Weird
Technology in 1980 was... well, it was 1980.
Most of the "video" you see on YouTube or in documentaries today is a mix of three things:
- The Rosenquist Stills: Interpolated by modern AI to look like fluid motion.
- USGS Surveillance: Scientists like Don Swanson were filming from fixed-wing aircraft using 16mm movie cameras. This is where we get the high-angle shots of the ash plume rising 15 miles into the sky.
- News Choppers: Local news crews arrived within an hour, capturing the lahars destroying bridges on the Toutle River.
"Vancouver! Vancouver! This is it!"
We can't discuss the footage without mentioning the audio. David Johnston, a 30-year-old volcanologist, was stationed at Coldwater II, a ridge six miles away. He was the one who radioed in the start of the eruption.

His last words: "Vancouver! Vancouver! This is it!"
He was standing right in the path of the lateral blast. The ridge he was on was eventually renamed Johnston Ridge in his honor. When you visit the Johnston Ridge Observatory today, you're standing near the spot where he was swept away.
How to See It Today (Responsibly)
If you’re planning a trip to Washington to see the crater, don't just watch the volcano eruption video mt st helens on your phone. Go to the actual site.
- Johnston Ridge Observatory: This is the best spot for the "view." You can see the crater and the "hummocks"—the giant chunks of the mountain that landed miles away.
- The Science Center: They play the footage on big screens. It’s much more impactful when you can see the actual scale of the destruction through the window right next to the screen.
- Ape Cave: If you want to see what the inside of a volcano looks like (from a much older eruption), this lava tube on the south side is incredible.
Actionable Steps for History Buffs
If you're looking for the most authentic records of the 1980 eruption, skip the over-edited "disaster porn" on social media. Start here:
- Search the USGS Digital Data Release: They recently released hours of raw, unedited 16mm and Super 8 footage from the 1980-1982 period. It shows the real, slow-burn terror of the dome growth.
- Read "In the Path of Destruction" by Richard Waitt: He’s a USGS geologist who interviewed hundreds of survivors. It provides the context that the grainy videos often miss.
- Check the WSDOT Archives: They have incredible footage of the bridges being wiped out by mudflows, which helps you understand how the volcano affected people hundreds of miles away.
The 1980 eruption wasn't just a geological event. It was a human one. The videos we have are legacies of people who, in their final moments, decided that documenting the truth was more important than anything else.
Next time you watch that gray cloud roll over the screen, remember Robert Landsburg lying on his backpack. It makes the footage feel a lot heavier.
Go to the Mount St. Helens National Volcanic Monument website to check current trail conditions before you visit, as the landscape is still technically "active" and prone to washouts.
