Mount Rainier Mount Rainier is one of the 16 Decade Volcanoes. The most recent recorded volcanic eruption was between 1820 and 1854, but many eyewitnesses reported eruptive activity in 1858, 1870, 1879, 1882 and 1894 as well. Although Mount Rainier is an active volcano, as of 2010 there was no evidence of an imminent eruption.

New York - Required Minimum Hours? We are considering offering voluntary time off on slow work days. The new supervisor is insisting there is a law that requires NYS employers to pay hourly employees a minimum of 4 hours if the employee is punched in (on the clock) for more than 30 minutes. I have never heard of such a thing.

- The largest eruption of Mount St. Helens in recent history occurred on May 18, 1980, when a cataclysmic eruption removed most of the northern face of the mountain. At 8:32 a.m. PDT, the summit collapsed into a rock debris avalanche that released a lateral gas explosion.

US History The Mount St. Helens eruption of May 18, 1980 was the most economically destructive volcanic eruption in the history of the United States causing over $1 billion of damage. Around 200 houses were destroyed and 57 people were killed by the blast.

Mount St. Helens Between 1980 and 1986, activity continued at Mount St. Helens, with a new lava dome forming in the crater. Numerous small explosions and dome-building eruptions occurred. From December 7, 1989, to January 6, 1990, and from November 5, 1990, to February 14, 1991, the mountain erupted with sometimes huge clouds of ash.

Mount St. Helens erupts Mount St. Helens erupts. Mount St. Helens in Washington erupts, causing a massive avalanche and killing 57 people on this day in 1980. Ash from the volcanic eruption fell as far away as Minnesota. Seismic activity at Mount St. Helens, which is 96 miles south of Seattle, began on March 16. A 4.2-magnitude tremor was recorded four days later and then, on March 23-24, there were 174 different recorded tremors.

- Mount Rainier. Mount Rainier (pronounced: /reɪˈnɪər/), is the highest mountain of the Cascade Range of the Pacific Northwest, and the highest mountain in the U.S. state of Washington. It is a large active stratovolcano located 54 miles (87 km) south-southeast of Seattle, in the Mount Rainier National Park. It is the most topographically prominent mountain in the contiguous United States and the Cascade Volcanic Arc, with a summit elevation of 14,411 ft (4,392 m).

The Most Dangerous Mountain In The United States: What Would Happen If Mt. Rainier Erupted? On May 18th, 1980, Mount St. Helens erupted with the power of 500 Hiroshima bombs. At the time, very few scientists anticipated that Mount St. Helens was capable of such a powerful eruption. But Mount St. Helens is not even the most dangerous volcano in the state of Washington. If Mount Rainier were to erupt with the same force that Mount St. Helens erupted in 1980, the loss of life would be far, far greater.

Is Mount Saint Helens about to wake up and throw a tantrum? The USGS recorded a number of earthquakes under Mount Saint Helens on Sept. 23, 2004, and the volcano finally erupted on Oct. 1, 2004 and lava stopped flowing in 2008.The volcano eruption did cause a lot of damage to the area around it.However, the damage caused by the eruption was nowhere near to what it was in 1980.On May 18, 1980, Mount Saint Helens erupted and the U.S. witnessed the worst volcanic disaster that savaged miles of areas around it.he USGS recorded a number of earthquakes under Mount Saint Helens on Sept. 23, 2004, and the volcano finally erupted on Oct. 1, 2004 and lava stopped flowing in 2008.

The Hazards of Mount Rainier by Cory Zellers Some of Mount Rainier's hazards are not associated with an eruption. Avalanches, landslides, floods, and lahars can be caused by any of the volcano's thirty earthquakes that occur each year.

Mount Rainier It is the most topographically prominent mountain in the contiguous United States and the Cascade Volcanic Arc, with a summit elevation of 14,411 ft (4,392 m). Mt. Rainier is considered one of the most dangerous volcanoes in the world, and it is on the Decade Volcano list. Because of its large amount of glacial ice, Mt. Rainier could potentially produce massive lahars that could threaten the entire Puyallup River valley.

Mount St. Helens Awakening On 10-Year Anniversary of Eruption Ten years ago, on Oct. 1, 2004, Mount St. Helens awoke dramatically from an 18-year slumber, explosively shooting steam, gas and volcanic ash thousands of feet in the air. Fast-forward a decade and we’ve recently witnessed a similar, and far deadlier, scenario play out as Japan’s Mount Ontake erupted without warning on Sept. 27, killing at least 36 people.

Mount St. Helens Mount St. Helens is most notorious for its major 1980 eruption, the deadliest and most economically destructive volcanic event in the history of the United States. Fifty-seven people were killed; 250 homes, 47 bridges, 15 miles (24 km) of railways, and 185 miles (298 km) of highway were destroyed.

Major Eruption Imminent? Earthquake Swarms Reported At Mt. Hood, Mt. Rainier And Mt. St. Helens If Mt. Rainier were to erupt as powerfully as Mount St. Helensdid in its May 18, 1980, eruption, the effect would be cumulatively greater, because of the far more massive amounts of glacial ice locked on the volcano compared to Mount St. Helens and the vastly more heavily populated areas surrounding Rainier.

What type of eruption does Mt. Rainier produce? The mountain is actually a dormant volcano that last erupted some 150 - 175 years ago; it covers 100 sq mi (260 sq km) and is surrounded by the largest single-mountain glacier … system in the continental U.S., with 41 glaciers radiating from the broad summit.

- The cataclysmic eruption of Mount St. Helens, Washington, on May 18, 1980, formed a deep north-facing horseshoe-shaped crater. Small eruptions from 1980 to 1986 built a lava dome. The lava dome can be seen here steaming within the crater.

- Even a mountain-building eruption, however, is likely to be rife with explosive phases, especially toward the beginning as it would 'clear the pipes.' Mount Rainier erupted as many as 6 times in the 1800s, but -- aside from tremors -- was quiet throughout the 20th century and, thus far, the 21st century.
