Dr. David Okrent, ACRS From:
George'A. Thompson, Consultant to ACRS
Subject:
Report on the Subcommittee meeting on Extreme External Phenomena, Los Angeles 1-29 and 1-30, 1981 The main thrust of this meeting, a progress report on the Seismic Safety Margins Research Program, was un-inspiring.
I do not want to dwell on what others must also have observed.
Briefly, however, much o f the re-search is so method-oriented, so non-physical and so lacking in intermediate, testable goa~
that it =ay never be used.
Bernreuter's work is a notable exception.
His interaction with staff (Reiter) is likely to produce both short-and long-term benefits.
'71th further progress, it should be possible to use Bernreuter's probabilities to predict a summation of seis=ic moments per time interval for various regions and to compare this with geologically studied moment rates o f faults.
Such a comparison might provide a val-uable consistency check for bridging to the longer term.
