   European Stars And Stripes (Newspaper) - September 27, 1986, Darmstadt, Hesse                                The Walla came tumbling town in May 1983 when a Strong quake  on the Rickmar scale struck coatings calif., revealing a previously unknown fault. West coast quake fears shift to lesser faults by Robert Lindsey new York times experts Are beginning 1o pay Mote attention to inc possibility of a major temblor in California Al some Point other than inc san Andreas fault. Their initial findings Are not Likely to Comfort san Francisco residents an analysis by slate seismologists concluded thai a severe earthquake on the Hayward Ault a 62-mile Long North South fissure that cuts across the urbanized northeastern Edge of he san Francisco Bay area would constitute one of the most devastating natural disasters that could conceivably strike this  an earthquake measuring 7 to 7.5 on the Richter scale the study slated could occur at any time in that area and cause 1,500 to 4,500 deaths depending on the Lime and Day and More than 100,000 injuries. Each unit on the Stchler scale represents a thirty fold increase in the Energy released in an earthquake. An earthquake measuring 6 on the scale can cause severe damage one Al 7 can cause widespread damage end one at 8 would be a great earthquake capable of causing tremendous damage. The san Francisco earthquake of 1906 was estimated to have been an 8. Another study is under Way in the los Angeles area regarding the Newport Inglewood fault which extends almost 50 Miles through a heavily populated coastal strip ram he City of Newport Beach northward to the Edge of Beverly Hills. Participants in the study say they Are finding a similar pattern of potentially enormous devastation. In recent years scientists and disaster preparedness officials have been examining the possibility Many say the inevitability of a super earthquake in the next two decades along the san Andreas fault which slashes across California from a Point near san Francisco to inc mexican Border. Historical studies indicate that earthquakes of Greal magnitude occur there Al predictable intervals As accumulated stresses Are released in huge bursts of Penl up Energy. The 1906 san Francisco earthquake was the Las i on the san Andreas fault Wilh a magnitude Al More than 8 recent ears of a great earthquake have focused on the Southern end of the fault near los Angeles where studies have shown one with a magnitude of 8 or More can be expected roughly every 145 years. The last such earthquake there occurred in 1857. And scientists say that if the Cycle continues Southern California can expect another major temblor on the san Andreas fault relatively soon. Some seismic Fety experts now say the state s residents could face an even greater Clanger irom earthquakes along lesser known faults beneath More populated areas. The san Andreas fault is so Miles from downtown los Angeles in the  Tousson r top Pozada. A seismologist for the California division of mines and geology said in an interview while both he Hayward and the Newport Inglewood faults Cut across very urbanized  in these areas even a magnitude 6.5 or 7 would be devastating he said. More than two million people live in the Hayward fault area and More than four million in the immediate area of the Newport Inglewood fault. The study completed this summer on the potential effects of an earthquake of a magnitude of 7 to 7.5 on the Hayward fault paints a picture of devastation. Earthquakes of this magnitude occurred there in 1836 and 1866, in addition to heavy loss of life and Many injuries. The study forecasts crippling damage to roads Bridges Airport runways Homes hospitals office buildings and other structures across an area ranging from communities 40 Miles North of san Francisco Loas far Sou 111 As san Jose. 50 Miles away Wilh damage heaviest in the Oakland area and fast growing suburbs East of it. The study directed by James f. Oats. The state geologist pred clod the wholesale disruption of medical services communications transportation and electric water and other Utility services. It forecasts splits in the Earth 10 Icet wide extensive settling and liquefaction of soil causing buildings to collapse especially at the Edge of san Francisco Bay where scores of buildings including some High rises have been erected on Landfill. While it will be Aboul a year before the study of the Impact of a magnitude 7 earthquake on the Newport Inglewood Lull is completed participants in the study say they expect to find a similar pattern. The last major earthquake on this fault which measured 6.3 on the Richter scale occurred March 10, 1933, and killed 130 people in and near the City of Long Beach. In the intervening years the area has been greatly developed. Experts say Uherc Are thousands of in reinforced masonry buildings in Southern California thai would be at risk in a severe Earl quake however Karl v. Steinbrugge professor emeritus at the University of California a specialist in structural engineering who is participating in the studies said building regulations Many of them stimulated by the Long Beach earthquake had led to the construction of Many buildings since 1933 designed to survive an earthquake. But even those regulations do not provide a guarantee that All of the state s recently built High Rise buildings and other structures would survive a severe earthquake. If we have an earthquake of magnitude e or 7 in a highly populated area self Brugge said we could have a major disaster at
