This chapter addresses important mitigation measures Mat can be taken to reduce the risk from the volcanic hazards described in previous chapters of this report. An effective risk-mitigation strategy can be undertaken only as part of a comprehensive strategy to understand the volcano.

There is also a need to provide information about current and planned projects, which is normally not communicated effectively through the scientific literature. Scientists and nonscientists alike would benefit from the establishment of a Mount Rainier Hazards Information Network accessible Trough the Internet.

From page 78... ...
In this context, responsible authorities include the National Park Service; local and state governments; and local, state, and federal emergency management agencies. This communication needs to be part of a comprehensive emergency response plan for scientists involved in volcano monitoring to communicate wig responsible authorities when conditions warrant, such as when precursory activity is detected or during actual events.

provides a summary of monitoring information, involved scientists, and pertinent contacts in the National Parks, National Forests, and other land holdings in the Cascades; the Cascades Volcano Observatory and the University of Washington maintain lists of contacts for responding to events at Mount St. Helens.

Several measures, if implemented, would significantly reduce risk from volcanic hazards to people and property in the region: . Risk analyses, to assess risks to populations and businesses from specific volcanic hazards such as tephra and debris flows.
|
From page 81... ...
. Hazard maps are spatial representations of areas at risk from lava flows, debris flows, tephra falls, pyrocIastic flows, lateral blasts, glacier outburst floods, massive slope failure, and similar events.

For example, He preparation of hazard maps using basemaps and GIS formats currently employed by state, county, and city planning agencies would increase their usefulness for land use planning and regulation and vulnerability analyses. Volcano scientists need to work closely with city planning agencies, engineering/public works departments, transportation agencies, and emergency-management coordinators to anticipate the consequences of volcanic hazard assessments for people, real estate, utilities, communications, and transportation activities.

The U.S. Geodynamics Committee believes that more effective risk-mitigation measures can be designed and implemented if natural and social scientists work together through the entire process.

, which requires state and local government agencies to include consideration of natural hazards in planning filture development. The issues of risk perception, hazard mitigation, and policy design as they relate to Mount Rainier are appropriate topics for social science
|
From page 86... ...
There is a limited amount of social science research concerning volcanic eruptions in the United States, principally Mount St. Helens (Sheets and Grayson, 1979; Johnson and larvis, 1980; Sorensen, 1981; Warrick and others, 1981; Diliman and others, 1982; Kartez, 1982; Leik and others, 1982; Perry and Greene, 1983; Saarinen and Sell, 1985; Buist and Bernstein, 1986; Perry and Lindell, 1986)

From page 87... ...
Between scientists arm the public. Scientists should work with educators and National Park Service staff in times of quiescence to inform He general public about the nature of volcanic hazards, people and property at risk, and options for risk reduction Trough presentations at schools and public meetings, by the preparation and distribution of high-impact educational materials, and by the development of displays on volcanic hazards and emergency response for visitors to Mount Rainier National Park.
|
From page 88... ...
There should be a critical evaluation of the existing social science literature as to its specific relevance to Mount Rainier. Future research on the social consequences of a Mount Rainier eruption should include development of a generic response mode} that could serve as a "check list" for understanding hazard response and mitigation.
