"California officials unveil new seismic map

SAN JOSE, Calif. (AP) — California geology officials have released an updated seismic map that they hope will improve earthquake preparedness and construction decisions.

The map, which had not been updated since 1994, includes more than 50 new fault lines discovered over the last two decades.

The map was unveiled on Tuesday at The Tech Museum in San Jose as the California Geological Survey celebrated its 150th anniversary. The Geological Survey also presented an updated version of a second map that identifies the makeup of rock and soil."
