Is that peak ground acceleration as measured in the free field? (Nitness Smith) Yes o / Q In your opening st tement, Dro Smith, you noted that we could approach the determination of the inistru~'aental „" 14 peak acceleration taken in the free~field by either a st~.tist caL /I —'pproach or a modeling approach, is that correctF 4 Okayo And in our d'scussion yesterday we got off on USGS Circular 672, and I have a series of questions for Dr o . Bolt regarding his,testimony on the USGS conclusion.a o Dro Bolt., at page 5846 of the transcript of yesterday you stated Blat you disagreed with ~Me procedures utiliz d by USGS to derive the figures in Table 2, I ba..'.ieveo (t'ritness Bolt) Yes: Nhat is your opinion regard'ng the scatter of 5c~gg peak instrumen. a3 accelerations ~="t have been recoxded for magnitude range"5.5 to 6,5? I'he -l A The e is considerah1e scatter. '. And do you have an opinion as to -- well, how many measurements do we have for instxumental pe~~c accelera- tions in the range of 6.5 to 8?

A ((fitness Bolt) Ne have very few This particu- I 4 som of. lar cixcular tabulates them in the appendix, t:xing the I order of, vrhen 'his was done, of +so, X think, and maybe three now Nhat are those thre ? Nelly X m think'ng about the eartnqvclges that are fai ly neax to Nxe source. One would .bc. the 1952 Kern County earthquake wh ch at the time the circular was written was allocated a magnitude of .7.7. Hut work at Ca" Tech, ance my won rereading of the Mood-Ande'rson records has now adjuster lv 5904 t' that magnitude, revised that magnitude really to 7.2 on the Richter Scale. 4 Ne have a record from the Tabataz earthqualce <' \ 1. a, in Xx'an that X mentioned yesterday, its HS magnitude was 7.7. And we have a =ecord-now from the Soviet Union near' ".,',;r...-..'-'~:-'he town cf Gazli, G-a-z™l-i, which has a surface wave mag- 3''4 nitude of X believe about, 7.2o That was no= available at. the time of the writing of'he l circularo Q How about Pacoima. * A Nellg Pacoima was availabl e. Xt' 6 . 5 magnitude.' Q So that gives us a total of four data points Ef fox'.5 and aboveo k A Yes Q Do you have an opinion of what we might ezoect h C ta see in terms of the scatter of data for instrumental peiJc "*" A accelerations for the magnitudes 6;5 to SP A Yes. X thinJc that we found the scatter on I both sides of about acceleration .7g. There will be some 19 found which are less than that and some gx'eater. And some of the scatter ~rill involve the topography on which the instrument is sittingo Some will involve the surficial 22 conditions, 'soil conditions. Some will involve the mechanism ', 23 of the earthquake. So there are a numbex of reasons why there vill I. be scatter about central value 25 this 5905 ml-.;05 0 Nelly I d'3,ike to limit olzz'i Ques- ions 'to '+NB L I in'strument:a3 peak accelara+iozls recorded, V' ' very was spealcing to tl:at.. .*' 'I' Q T~le 'f3.gure;the%4 yQQ gP ~ Vg ~ Goes 'phcUQ repre sent. the instrumental peale r;acorn'ing~c" ' A Zt, ~mule. be, yes. today I spoke about, the peak acce3.erac;ion I'e. 1 becoming asymptotic to some value batmen .6g and;.Sg bo" ", ".,')."',', i',that 1ijht; I m speculating that; Vlere ~chill be so.-ne,. average t 7 level '~ t21G scaC'her around 833ou"t o Vgo 0 Xse~ 'me see if 7.
