Earthquakes continue to rattle Mount Rainier, now biggest seismic event in recent history
While considered an active volcano, Mount Rainier hasn’t erupted in at least a century, possibly much longer. The U.S Geological Survey said there was no physical evidence to confirm a reported 1894 eruption, nor eruptions earlier in the 18th and 19th centuries. The last eruption with strong geologic evidence happened about 1,000 years ago.
