R. E. Jackson MEETING
SUMMARY
GETR, JANUARY 25, 1978 The primary points of staff discussion were in the following areas:
1.
The size of the earthquakes which could be generated by the Calaveras fault and the Verona fault. and the resultant accel-eration and ground motion spectra that could occur at the GETR site as a result of.such an occurrance.
- 2..The time history of surface fault rupture along the Verona fault relative to the time history of vibratory ground motion due to an earthquake on the Calaveras fault and/or the Verona fault.
3.
That the proposed 1.02 meters' of surface fault displacement would bound the approximate average net slip observed along the Tajunga and Lakeview fault segments following the 1971 San Fernando earthquake.
I l
4.
That data acquired for the 1971 San Fernando, California, and the l
1969 Meckering, Australia ~ earthquakes would be most representative of the tectonic environment and type of event that might be postu-lated for an earthquake on the postulated Verona fault.
5.,
That any-data that would further support the absence of the Verona fault or serve as support for providing a limitation on the possible length of fault would be extremely useful in our review of GE's response to the NRC's show cause order and should be provided as soon as possible.
(The Earth Sciences Associates representative indicated that further information' was available along the route 84 valley and that an analysis of gravity measurements of the Livermore Valley had been completed.)
