it has erupted many times
Crater Lake formed after Mount Mazama, a volcano, collapsed during a cataclysmic eruption.
It's difficult to predict eruptions as records are not aways kept, or accurate. Mount Pinatubo is believed to have first erupted 17,000 years ago with successive eruptions throughout the years. Major eruptions have been identified at 9,000, 6,000, 5,000, 3,900, 2,300 and 450 years ago. There may have been many more minor eruptions. The last major eruption was in 1990/1991. See related link for more information.
It did not have a Richter scale rating. The Richter scale is used to rate earthquakes, not volcanic eruptions. Volcanic eruptions are rated on the Volcanic Explosivity Index. The 1991 eruption of Mount Pinatubo was a VEI 6, described as a colossal eruption.
The 1980 eruption was very explosive. Ash was blown 80,000 feet into the air and the mountain is a quarter mile shorter than it was before the eruption.
The last eruption of Mount Mazama was 7,700 years ago, too long ago for us to know how many died in the explosion.
