It is as old as time tells!

There isn't any imminent threat of Mount Rainier erupting; nor are there any signs of it ever erupting any time within our lives.

Clearly the greatest environmental effect would be the lahar flows which would wash away towns and work sites in their path and bury the area in avalanche debris and mud. Previous debris flows filled river valleys to a depth of hundreds of feet near the volcano, and buried the land surface under many feet of mud and rock sixty miles downstream. A major lahar flow would significantly alter the course of rivers in the area and dump significant amounts of material - much of it toxic to aquatic life - into the ocean.

As well as I can determine, none from volcanic eruption. It has not erupted for well over 150 years, so the area was very sparcely populated and apparently there were not even any permanent Native American habitations in the immediate vicinity, so if there were any fatalities, they would not have been recorded. In recent years, there have been about three mountaineering fatalities annually, but I could not find a total number.

Mount Rainier is a stratovolcano a few hundred kilometers inland of the subduction zone between the Juan de Fuca and North American tectonic plates.

Mount Rainier, Washington, isn't located on a divergent plate boundary but a convergent one. The Juan de Fuca Plate off the coast is pushing under the northern US and Canada, creating volcanism (such as Mt St Helens).

Mt. Rainier is a stratovolcano composed primarily of rhyolite or rhyo-dacite. This means that the volcano has the potential for highly explosive eruptions, similar to other volcanoes in it's arc. Rainier is part of the Cascades Volcanic Arc, which is the same volcanic arc as Mt. St. Helens.

Mount Whitney (14, 497 ft.) is the tallest mountain in the contiguous United States. Mt. McKinley (Denali), in Alaska, is at 20, 320 ft. the tallest mountain in the US, and also the tallest in North America. Mt. Rainier, at 14, 409 is close behind Mt. Whitney.

It should be noted, however, that Whitney and Rainier are different kinds of mountains. Whitney, formed of granite, is part of the Sierra Nevada range, a result of a "fault block" that involves the tilting of a massive piece of the Earth's crust. As such, it is extremely rugged, and much steeper on the east side than on the west. On either side, it is a more difficult climb than Rainier, requiring a lot of technical work.

Mt. Rainier is a large, active volcanic cone. The most recent recorded volcanic eruption was between 1820 and 1854, but many eyewitnesses reported activity in 1858, 1870, 1879, 1882 and 1894 as well.

As of 2008, there is no evidence of an imminent eruption. However, an eruption could be devastating for all areas surrounding the volcano, which includes Bellevue, Seattle, Tacoma and surrounding areas of Western Washington. Formed from lava flows, its sides are relatively shallow, smooth slopes, and it is easily climbed -- although not without risk. Glaciers, rather than walls, are its most notable obstacles.

About 1.7 million.

It proves that the geological evolution of planet earth continues.

The Cascade volcanoes stretch from British Columbia, Canada to California, United States. Mount Rainier is among the Cascade volcanoes and is located in the U.S. state of Washington.

It's difficult to be precise, but the oldest rocks found, give an age of about 593,000 years.

Mount Rainier's elevation is 4,393 meters.

I'm pretty sure that Elbe is the closest. I'll look when I go there next.

My new answer: Eatonville, b/c it iss on the base of Mount Rainier.

In Washington State

The cotopaxi volcano is in Mexico in the Andes mountins and about 45 kilometres away from south America.

There is no volcano by the name of Mount Saint Rainier. This question confuses two different volcanoes: Mount St. Helens and Mount Rainier. Mount St. Helens famously unleashed a massive eruption on May 18, 1980, but has produced smaller eruptions as recently as 2008. Mount Rainier last erupted in 1894.

Much of Mount Rainier is composed of andesitelava flows. Lava flows may accompany explosive eruptive activity, but they occur more often after explosive activity declines. The term "andesite" refers to the chemical composition of the rock. Andesite lavas tend to be moderately viscous and rather slow moving: on gentle slopes, they may move much more slowly than a person can walk.

Mount rainer farted on people.hi i am Emily and i am eleven and i go to lake castle private school. i am young but i do know alot. people come on here and think they know everything. i don't mean to be a snob but they so. I think i am very intellegnt and i know everything. Guess what ive been reseraching this for the past 4 years. So suck it please(:

No, not even close. Mount Rainier has an elevation of 4,392 feet. The highest point in the U.S. is Mount McKinley at 20,237 feet. The highest point in the contiguous United States is Mount Whitney at 14,505 feet.

Mount Rainier is in the United States.

Right now Mount St Helens is dormant.
