The US Geological Survey is intensifying its monitoring efforts at multiple volcanoes in the Cascade Range of the Pacific Northwest, as experts observe heightened seismic activity. Mount Rainier, situated merely 59 miles from Seattle and close to four million residents, is considered one of the most hazardous volcanoes in North America due to its substantial glacial ice cover. A significant eruption or lahar could result in volcanic mudflow affecting populated river valleys within a matter of hours. Experts caution that the volcanic hazards in the Pacific Northwest are often underestimated. Federal emergency management officials are revising evacuation plans for the communities most at risk.
