Mount Rainier is one of the 16 Decade Volcanoes. The most recent recorded volcanic eruption was between 1820 and 1854, but many eyewitnesses reported eruptive activity in 1858, 1870, 1879, 1882 and 1894 as well. Although Mount Rainier is an active volcano, as of 2010 there was no evidence of an imminent eruption.
