Washington 25, D. C.
Re Pacific Gas aad Electric Co..
Bodega Bay Atomic Park Unit No. 1, l
Docket No. 50-205
Dear Mr. Hadlock:
Not having heard from you any further on the matter of submitting a final draft of my report to Mr. Lowenstein I r.m taking the liberty of listing below a few changes that I have made in the text of the report and a set of illustrations in which certain changes have been mados
- 1. Page 3, line 5, eliminate period and add "in the central portion of a shaken area.
- 2. Page 3, last line of footnote, change (4) to (5 and 6).
- 3. Page 9, middle line of table, change 1-11 and 111 to Roman I-II and III, respectively.
- 4. Pege 9, 5th line from bottom, word Figure is misspelled.
- 5. Page 10.10th line from top, change a-6 to a-b.
TableI.
3 5th column heading. Insert superscript after " Magnitude".
Year 1865, 4th column, change VII _LI to VIII-IX 1907, 2d. col., date is Sept. 20 (insert 20)
Footnote (2), Add, " Intensity evaluations are from Reference 1".
(4), Octit " apparent by".
Add this new sentences" Tabulated fi ures refer to intensities along the coastal areas of Humboldt t
Cor.nty".
Appendix I Reference 11.
Symposium is misspelled.

e Concernin6 the illustrations: Figures 3 and 5 have been sepa-rated and one of the explanations in Figure 4 has boon shortened in the interest of clarity. Some minor modifications have been made in other illustrations as you suggested.
Thank for the copy of AEC Report TID-7024 entitled Nuclear Reac-tors and Earthquakes. Your attention is called to the followin6 items in the report concerned with the subject of earthquake intensity.
1.
In the middle of page 15 it states " Propagation from a point source is assumed" which is contrary to the Housner thesis that the soucco is planar in character. The authors (?) state that "the (cir-cular) pattern shown would be elongated in the case of a shallow shock involving a long fault break".
In my opinion this would most likely result from a succession of point sources and the character of the re-iG onal geology. Nowhere, however, including the various foirmulas in-volvin6 epicentral distance, does the author advocate a planar energy source. The circular isoseismals on page 16 are not the basement rock isoseismals which I consider of fundamental importance in understanding intensity distribution. It is not made clear just how the distances are chosen for the re.dii of the various circles; they are " idealized" isoseismals which might mean anything. The paper shoxs at least a cautious trend toward the point source idea and circular isoseismals.
2.
It is noted in the intensity tables on page 13 that intensity NM-12 might reach 5 g.
In my report the upper limit suggested is a-round 1.5 g. The liitroduction to the Hanford report states "The ap-proach to earthquake-resistant structural engineering was quided by G. W. Housner --- ". How could Housner approve 5 g for MM-12 when in recentAECreportsheadvocatesabout1/3 6 as a maximum possible in basement rock?
i In connection with the Hanford report you may not be aware that I j
was also called in as a seismological consultant. My report was pub-l lished by AEC (for the General Electrical Co.) as research and develop-l ment report HN-63832 entitled "Seismologoial Investigations in the Han-for Area, 1958-1959". The report is dated Nevember 10, 1959. This report goes much more into the local seismicity than AEC report TID-7024. At that time the relationships between ground motion, intensity, ma5nitude, etc. had not been explored as thoroughly as in my current report on Bodega Head.
A few days ago several reprints of my paper on "Seienic Forces on Engineering Structures", with discussions, were mailed to you for dis-tribution within the L & R Division. The discussion reveals the violent opposition of some influential people toward some of the intensity con-cepts expressed in my current AEC report now in preparation.
In10ye[s of this type of criticism I have never been able to put my finger on the individuals who are responsible for'this criticism. NaturaIV, I would j
not be surprised to learn the.t the same forces are exertin6 some influ-l ence in the current AEC studies. You will note that a large part of my j
ASCE discussion is taken up with a defense of the intensity - velocity I
