A group of 75 scientists led by Alan Levander of Rice University in Houston visited Mount St. Helens this week, to create seismic waves by controlled explosions, that will enable them to study the mountain with a new method that is akin to an "ultrasound and a CAT scan" of the volcano's "internal plumbing."
If you’re in the vicinity of Mount St. Helens tonight and feel a sudden rumble, don’t panic: It's just scientists detonating parts of the volcano for an ultrasound. Researchers from a conglomerate of universities spent the weekend placing 3,500 seismic sensors and will be setting off 23 planned explosions...
Later this month, scientists will set explosive charges on Mount St Helens as part of an effort to study the seismic geology of the Pacific Northwest.
What could go wrong with setting off explosives all around an active volcano? As scary as it might sound, this is a carefully planned experiment to peer inside Mount St. Helens' mysterious underground magma chamber. No, we aren't blasting...Show More Summary
Scientists are embarking on a research expedition to improve volcanic eruption forecasting by learning more about how a deep-underground feeder system creates and supplies magma to Mount St. Helens. They hope the research will produce science that will lead to better understanding of eruptions, which in turn could lead to greater public safety.
Ape Canyon is actually a gorge along the northeast shoulder of Mount St. Helens in Washington state. Of course, the name “Ape Canyon” didn’t come from just anywhere. The name refers to a supposed encounter between a group of miners and several 'apemen' in 1924, an event eventually integrated into Bigfoot folklore. Show More Summary
Mount St. Helens has magma rising to the surface 34 years after it erupted, proving that volcanic activity remains alive and well inside the mountain. The volcano in southwest Washington made breaking news after it erupted May 18, 1980. It destroyed vast forests, vegetation, and ash was spewed as far as Interstate I-5. According to
There is some mild earthquake activity and signs of long-term uplift on Mount St. Helens, scientists announced on Wednesday, but they do not believe that the Washington State volcano will blow anytime soon. Mount St. Helens' massive 1980 eruption scattered its peak across the Pacific Northwest. Show More Summary
After 1980 and 2004, magma accumulated in the reservoir beneath Mount St. Helens, which scientists say adds no risk of eruption
My God...Nothing beautiful today; nothing inspiring... Twenty years ago I paid my first visit to the destruction wrought by the eruption of Mount St. Helens. I stood on a high viewpoint on Windy Ridge after a long drive through downed...Show More Summary
New images of Washington's Mount St. Helens have been recently discovered. Reid Blackburn, a staff photographer for the The Columbian newspaper, took photographs in a flight over the volcano in April 1980. When he got back to the paper's studio his roll was set aside and never developed. Until now. Learn more
Newspaper photographer Reid Blackburn died in the eruption of Mount St. Helens in 1980. This year, reporters at his paper — the Vancouver, Washington, Columbian — discovered a never-before-seen roll of photos he took flying over the volcano about a month before his death.
A new study by the University of Utah revealed that the hot molten rock beneath Yellowstone National Park is 2 ½ times larger than previously estimated, meaning the park’s supervolcano has the potential to erupt with a force about 2,000...
Beneath Yellowstone National Park lurks a vast caldera – a high-pressure volcanic cauldron brimming with enough gas and magma to make Mount St. Helens' 1980-eruption look like a middle school science project by comparison. Now, newly reported findings suggest this megavolcanic reservoir is even bigger than previously believed. Much, much bigger. Read more...
Evidence of an eruption 5,000 times larger than Mount St. Helens was found in the Utah desert, with traces of ash identified as far away as Nebraska.
The 1980 eruption of Mount St. Helens is regarded as the deadliest and most destructive volcanic blast in U.S. history. And yet, just thirty-three years later, life has returned to the area in almost equally impressive force, as newly released photographs illustrate. Read more...
When I was five years old, my parents took me to my very first IMAX movie—The Eruption of Mount St. Helens. Twenty years later, it's still one of my most memorable theater-going experiences. The technology has changed a lot since then (digital projection and 3D, among other things), but the magic of seeing a film in giant-screen format remains. Show More Summary
September is one of the best times of year to visit Mount St. Helens thanks to cooler temperatures and clear visibility. It's also the perfect time to help the staff complete a much needed one-mile trail to the nearby Ape Cave, the famous lava tube just south of the active volcano. Show More Summary
Statements like "a cubic mile of rock" take on new meaning when that cubic mile is laid out in plain sight, like God attacked the mountain with a cosmic ice cream scoop.
