Study: San Andreas May Be Longer

.c The Associated Press 

SAN MATEO, Calif. (AP) -- A new study concludes that the San Andreas Fault may
be longer than earlier thought and would cause significantly more damage if it
ruptures and triggers a major earthquake. 

The report released Thursday found that the section of the fault that begins
on the San Francisco Peninsula may be as long as 55 miles, not 32 miles long. 

The added mileage, in the event of a major earthquake, could quadruple the
amount of damage to strike the San Francisco Bay area. 

``It potentially exceeds Hurricane Andrew and Hurricane Hugo, and greatly
exceeds the Northridge quake,'' said Doug Sandy, Red Cross deputy director for
disaster services in the San Francisco Bay area. 

It means the fault could produce a 7.3 magnitude earthquake rather than the
7.1 predicted in a previous report. In San Francisco alone, damage could be
three to four times as heavy as planners had estimated. 

Up to 107,000 homes would be left uninhabitable, up from 45,700 homes, and 836
roads would be closed rather than 428, the report said, updating a report
released three years ago. 

The report did not contain estimates of casualties. 

A 300-mile stretch of the San Andreas ruptured in 1906, causing the great San
Francisco earthquake and fire. A section of the fault broke in the Santa Cruz
Mountains in 1989, and the Loma Prieta quake in the San Francisco Bay area was
the result. It killed 67 people and caused $6 billion in damage.
