Mount Rainier is one of the five strata volcanoes in the Cascade Mountain Range of Washington State. This fascinating iconic peak stands 14,411 feet high and is the highest peak in Washington State and the entire Cascade Range. Mount Rainier is also the most topographically prominent mountain in the contiguous United States.
Since Mount Rainier is an active strata volcano and part of the Cascade Range, many wonder if there is a likelihood of Mount Rainier erupting within the next fifty years. The last time Mount Rainier erupted was 1000 years ago.
Mount Rainier dramatically changes with the seasons. In the winter months, it’s covered in snow, while in the summer, the lower slopes of the mountain become lush and green with wildflowers in bloom. Mount Rainier is still considered to be one of the most dangerous volcanoes in the United States. Potential hazards may include pyroclastic flows, large lahars, and ash fall, which could all impact the communities that lie downstream.
The United States Geological Survey (USGS) closely monitors Mount Rainier for signs of volcanic activity, including seismic activity, gas emissions, and ground deformation. Based on these monitoring efforts, scientists assess the risk of an eruption. The USGS has classified Mount Rainier as a “Very High Threat” volcano.
