SUMMARY OF CONCLUSIONS 231 



fault lines of Southern California, which some seis- 

 mologists look upon as probable sites of future move- 

 ment, are largely things of past geologic time. It is 

 probable that progress towards seismic stability has 

 progressed much farther in Southern California than 

 in the northern part of the state. 



All of the few buildings hitherto injured by shocks 

 in Southern California were structurally weak and 

 condemable. Experiences of the past show that no 

 moderately, well-constructed buildings has ever been 

 destroyed by earthquakes in Southern California. 



Many of the great geologists and seismologists are 

 on record in opposition to Dr. Willis' conclusions that 

 times and severities of earthquakes can be predicted. 

 The Dominguez fault is the only allegedly dangerous 

 one at Los Angeles. The authorities of the University 

 of California at Los Angeles, by permitting the new 

 buildings at Westwood to be built almost astride of 

 this line have shown their lack of fear of harm from it. 



K the risks at San Francisco and Santa Barbara 

 are to be rated high because these cities are located 

 near lines of more active seismicity, then the risk at 

 Los Angeles, situated farther from such lines, should 

 not be as much. Dr. Willis himself has stated that the 

 danger is practically eliminated at a distance of ten 

 miles from one side of the rift, and the experience at 

 San Francisco and Santa Barbara have shown this fact 

 to be true. The City of Los Angeles is at least thirty 

 miles away from the nearest of them. 



I have shown that the data upon which Dr. Willis 

 has created his theories that "we are to have a dan- 

 gerous earthquake in Southern California at an early
