Mount St. Helens

The massive bulge, the earthquake, and the snow melting due to magma rising.

Monitoring systems have been put in place to track volcanic activity and provide early warnings. Hazard mitigation strategies have been developed, including restricted access to the danger zone and emergency response plans. Public education and outreach efforts have also been conducted to raise awareness of the potential risks associated with the volcano.

According to historical records, over a thousand ships were launched in honor of Helen of Troy after her abduction by Paris. These ships were part of the Greek fleet that sailed to Troy to rescue her, leading to the famous Trojan War.

Mount St. Helens erupted on May 18, 1980. It was a catastrophic eruption that resulted in the loss of lives and significant destruction of the surrounding area.

57 people died in the May 17, 1980 eruption.

Eruptions for about 150 to 200 years followed by dormancy for an equal or extended period of time. Most of the eruptions are minor ones with a few major ones in the mix. That's just based on last 2000 years after its became more like a stratovolcano in what it emitted.

Mount Saint Helens is located south of Seattle, Washington. In recent history, it has had a major eruption in 1980, and has been active in varying degrees of intensity since then. Which of these active periods can be classified as eruptions is up for debate.

David A. Johnston, the vulcanologist, was killed when he was manning an observation point on Mount St. Helens when it erupted in 1980. He was swept away by the blast created by the collapse of the mountain's north flank.

David Johnston was melted by the gasses of Mt.st.Helens. Harry Truman

was killed by a pyroclastic flow, burying him and his lodge under 150 feet of volcanic debris. Overall, they were both killed by the pyroclastic flows.

Harry Randall Truman (not to be confused Harry S. Truman) was an elderly man who lived in a lodge near the foot of Mount St. Helens. He became something of a celebrity when he refused to leave despite warnings from scientists. Truman died along with 56 other people when Mount St. Helens erupted on May 18, 1980.

Niether. The eruption of 1980 did not produce lava flows, it produced pumice and ash. Afterward it started building a dome of dacitic lava. Pahoehoe and a'a are basaltic lava, which has a different composition and a much lower viscosity.

Yes, the eruption of Mount St. Helens triggered massive mudflows known as lahars. These lahars were a mix of volcanic debris, water, and ash, and they flowed down the slopes of the volcano at high speeds, causing significant destruction to the surrounding areas.

Actually, the North American Plate and the Pacific plate form a transform boundary. There is no volcanism related with a transform boundary. Mt. Saint Helens was created by the interactions of the North American plate and the Juan de Fuca plate. The Juan de Fuca plate is an oceanic plate, made of material which is more dense than continental plates, such as the North American plate. The Juan de Fuca plate and the North American plate are currently smashing into each other, and Juan de Fuca plate is subducting (sinking below) because it is denser. this allows for magma to come to the surface, and creates a volcano.

Please disregard the first answer as it is complete and utter jank.

On May 18, 1980, the eruption of Mt. saint Helen in south west Washington state, disrupted the lives of thousands and changed more than 200 sq. miles of rich forest into a grey, lifeless landscape. More than 26 yrs. later the land around the mountain heals it self slowly.

The eruption started at may 18 1980 at 8:32 am

The mountain, before eruption was about 9677 feet and now it is about 8363 feet

57 people were killed in the eruption and 21 bodies were never recovered

7000 big game animals, millions of birds,12 million salmon and small mammals were also killed.

All depends on the size of the eruption. If it were a big eruption then it could bellow ash and smoke into the atmosphere and cause sunlight and heat to be blocked around the world making the earths temperature fall for a little while. Also it will send gasses like methane, carbon dioxide and sulpher into the atmosphere, adding to the greenhouse gas level and maybe contributing to global warming.

Mount St. Helens is considered a stratovolcano, not a crater or caldera. It erupted in 1980, causing the top of the mountain to collapse and create a horseshoe-shaped crater.

The eruptive effects were felt worldwide for a full year after the 1980 eruption of Mt. St. Helens. There was enough carbon dioxide as well as sulfur dioxide erupted from the volcano that it was able to measurably reduce global temperatures by 1.5 degrees. The heaviest impacted area from the eruption was the area directly to the north that was part of the blow down zone following the lateral blast from the volcano. There was also however a big impact on the central United States due to the ash fall that killed crops and injured live stock.

99999.000000 To date there have been just over 200 deaths on Mount Everest, many of the bodies still lay on the slopes where they fell.

Thomas J. Dryer hiked up Mount St. Helens in 1853

Mount St. Helens erupted on May 18, 1980, at 8:32 a.m. local time. The eruption sent plumes of ash and smoke reaching as high as 80,000 feet into the air, devastating the surrounding landscape and causing significant loss of life and property.

Helen's last name is Keller. Helen Keller was an American author, disability rights advocate, and the first deaf-blind person to earn a Bachelor of Arts degree.

The land around Mount St. Helens was primarily used for forestry, mining, recreation, and wildlife habitat before the 1980 eruption. After the eruption, the area has been designated as a National Volcanic Monument and is now primarily used for research, education, and recreation.

The eruption of Mount St. Helens in 1980 was triggered by a combination of an earthquake, causing the north face of the mountain to collapse. This collapse released pressure that had built up within the volcano, allowing magma to erupt explosively from the mountain.

The eruption of Mount St. Helens in 1980 was a significant event, but not the greatest explosive eruption in the last two hundred years. This title is often attributed to the eruption of Krakatoa in 1883, which had a larger impact on a global scale.

The eruption of Mount St. Helens in 1980 caused widespread destruction of forests, rivers, and ecosystems in Washington state. It also led to the loss of wildlife habitats and altered the landscape significantly. The ash plume spread across multiple states, impacting air quality and visibility in neighboring areas.
