Mount Rainier National Park is a national park of the United States located in southeast Pierce County and northeast Lewis County in Washington state. [3] The park was established on March 2, 1899, as the fourth national park in the United States, preserving 236,381 acres (369.3 sq mi; 956.6 km 2) [1] including all of Mount Rainier, a 14,410-foot (4,390 m) stratovolcano.
The snowcapped peak of Mount Rainier, which towers 4.3 kilometers (2.7 miles) above sea level in Washington state, has not produced a significant volcanic eruption in the past 1,000 years.
Washington has a majority of the very highest volcanoes, with 4 of the top 6 overall, although Oregon does hold a majority of the next highest peaks. Even though Mount Rainier is the tallest, Mount Shasta in California is the largest by volume, followed by Washington's Mount Adams. Below is a list of the highest Cascade volcanoes:
Volcanoes are informally described as erupting, active, dormant, or extinct, but the definitions of these terms are not entirely uniform among volcanologists. The level of activity of most volcanoes falls upon a graduated spectrum, with much overlap between categories, and does not always fit neatly into only one of these three separate categories.
The Mount Rainier Volcano Lahar Warning System consists of two separate components, operating in tandem: Acoustic Flow Monitors (AFM) and the All Hazard Alert Broadcast (AHAB) sirens. The AFM system was developed by the United States Geological Survey (USGS) in 1998 and is now maintained by Pierce County Emergency Management.
