③ 摘要
Loma Prieta地震和它的余震導(dǎo)致了一系列商業(yè)結(jié)構(gòu)的大面積順壞損壞.正如這個(gè)量級(jí)的典型地震一樣,有一大批地理范圍受到了影響.被波及的地區(qū)包括8個(gè)郡,從南部的Monterey和San Benito,到北部的San Francisco, Alameda, 和 Contra Costa .總共有大約3000平方英里面積的建筑結(jié)構(gòu)遭受到了破壞.
盡管地震帶來(lái)的破壞面積很廣,但是這些破壞很零散.據(jù)估計(jì),最接近震中的地區(qū),包括Hollister, Los Gatos, Santa Cruz, 和 Watsonville 經(jīng)歷了最集中的破壞.再遠(yuǎn)一點(diǎn),僅僅是那些地基建在松軟的土質(zhì)上的質(zhì)量非常差的建筑物遭到了嚴(yán)重的破壞,這些土質(zhì)在地震的運(yùn)動(dòng)中中被破壞和坍塌.這和1985年的墨西哥地震產(chǎn)生的影響是相似的.
地震的影響是具有很強(qiáng)的方向性的.大多數(shù)破壞發(fā)生在從西北向東南方向延伸的狹窄地段,大約與San Andreas Fault平行.因此沿著 San Francisco 灣的許多地區(qū)逃脫了這場(chǎng)截難.

The Loma Prieta Earthquake and its subsequent aftershocks resulted in widespread damage to a variety of commercial structures. A large geographical area was affected, as is typical for an earthquake of this magnitude. The affected area encompasses eight counties, from Monterey and San Benito in the south to San Francisco, Alameda, and Contra Costa in the north. In total, building structures experienced damage over an area of approximately 3,000 square miles.
Although damage was widespread, it was also quite sporadic. As would be expected, areas closest to the epicenter including Hollister, Los Gatos, Santa Cruz, and Watsonville experienced the most concentrated damage. Farther away, heavy damage was generally limited to buildings of very poor construction founded on soft soils that failed or amplified the earthquake ground motions. This is similar to the effects noted in the 1985 Mexico City Earthquake.
Earthquake effects also tended to be highly directional. Most damage occurred within a narrow band that extends northwest to southeast, approximately paralleling the San Andreas Fault. Thus many communities along the margins of San Francisco Bay escaped serious damage
