PART SEVEN 



SUMMARY OF CONCLUSIONS 



In concluding this report a brief summary of the 

 premises upon which rests my refutation of earthquake 

 predictions for Los Angeles is in order. The accumu- 

 lative weight of data substantiates beyond a doubt my 

 deduction that Los Angeles is in no danger of a great 

 earthquake disaster. 



Following is a short statement of each step in the 

 progress of this report: 



Southern California is not Northern California and 

 the geologic conditions of the two regions are dif- 

 ferent. Consequently, their seismologic behavior is not 

 the same. 



Southern California is a part of a west-American 

 region of mild seismicity and no evidence can be 

 gathered from accurate historic data or from the 

 accounts of the oldest inhabitants that any earthquakes 

 of great intensity have taken place at Los Angeles 

 within historic times. 



No proof has been presented of the presence here of 

 the dangerous type of horizontal movements that oc- 

 curred along the San Andreas Rift at San Francisco 

 or of the transverse stresses that affected the Santa 

 Barbara district. 



The City of Los Angeles is remotely situated from 

 the three lines of maximum seismicity in California,
