Scientists from the United States Geological Survey are enhancing their surveillance of volcanoes in the Cascade Range as low-level seismic events persist beneath several significant volcanic regions in Washington and Oregon. Mount Rainier, located merely 59 miles from Seattle, is still regarded as one of the most dangerous volcanoes in the nation due to its extensive ice cap and closeness to millions of people. USGS experts indicate that while an eruption is not expected in the near future, the geological activities taking place beneath the Cascades align with historically active volcanic systems responsible for devastating eruptions with minimal notice.
