Abstract:
An evaluation of the geologic events of the last 10,000 years at Mount Rainier suggests that, if the past pattern of volcanic activity continues, a substantial steam, pumice, or lava eruption will occur on an average of once each 500-1,000 years. Furthermore, these eruptions predictably will be accompanied by destructive floods and mudflows along the floors of some valleys that head on the sides of the volcano. The purpose of this report is to describe the ways in which an impending eruption might be recognized, to discuss the effects that might be anticipated from an eruption, and to recommend ways in which potential threats to human life might be reduced or eliminated. In addition, the potential hazards at various visitor-use facilities and Park maintenance installations are discussed, and suggestions are made concerning the possible relocation of some of these facilities. The accompanying Appendix, "Procedures to follow in case of a volcanic eruption," is prepared in such a way that, if desired, it can be reproduced for distribution to Park Service personnel responsible for various installations at the Park.

The information given here concerning the eruptions of the last 10,000 years is summarized from Geological Survey Bulleting 1238, "Volcanic hazards at Mount Rainier, Washington," by Dwight R. Crandell and Donal R. Mullineaux, which is now in press.
