On October 17, 1989 at 5:04 in the evening a 7.1 magnitude earthquake struck the San FranciscoBay Area.
The ground shook for only fifteen seconds, but that brief quarter-minute started fires, destroyed highways, united San Francisco, caused the deaths of 62, delayed a World Series, broke the Bay Bridge, and inspired a university professor to write a book of poems called Loma Prieta – the name of the mountain at the epicenter of the quake and subsequently assigned to the disaster.

In the weeks and months after the quake, the overwhelming sentiment in San Francisco was “it could have been worse.” Although a strong earthquake, it was centered about 60 miles south of San Francisco in Santa Cruz County, meaning that the bulk of the destructive force was centered on the sparsely populated and mostly agricultural communities of Santa Cruz, Watsonville and Salinas. While these areas endured more devastation on a per-capita basis, San Francisco and Oakland coped with significantly more damage overall. The fabled 1906 earthquake registered magnitude 7.8 and caused four times more property damage to a San Francisco half as big as it would be in 1989.
In San Francisco proper, the statistics present a blunt description of the damage: 12 deaths. 300 injuries. Two billion dollars worth of destroyed property. (1989 Northern California Earthquake) The Marina district was the hardest hit — instead of standing on solid earth the whole neighborhood is constructed on sandy landfill and rubble dragged into the Bay during reconstruction after the 1906 earthquake. The fire department’s water mains were destroyed by the shockwaves in the suddenly liquefied ground, and only the quick decision to use fireboats in the Bay to fight fire on the land prevented the flames from engulfing more of the city. The top floors of many Victorian homes in the Marina district collapsed into the open, unsupported garage space on the ground floor. Only in 2013 did San Francisco introduce a mandatory retrofit program for these so-called “soft story” buildings (Mandatory Soft Story Program).
Absence of adequate shear walls on the garage level exacerbated damage to this structure at the corner of Beach and Divisadero Streets, Marina District.

The most enduring image of the Loma Prieta quake is that of a section of the Bay Bridge’s upper deck collapsed onto the eastbound lower deck. One person died when her car plunged into the 50-foot gap left by the missing section. In Oakland, 42 people were killed in one three-quarters of a mile stretch of a similar double-decker freeway that fell down in the quake. Called the Cypress Street Viaduct, it was the single most deadly place in the aftermath of the earthquake. It was not rebuilt. The California Highway Patrol’s report on the transportation deaths argued that baseball saved countless lives: “the afternoon commute traffic was lighter than usual for the Bay Area. This was directly attributable to the third game of the World Series … a large number of people were already at the stadium and an equally large number of people left work early to participate in pre-game activities” (1989 Loma Prieta Earthquake Summary Report).
The Loma Prieta earthquake was the first natural disaster to be broadcast live to the nation. Coincidentally striking the city mere minutes before the first pitch of Game 3 of the World Series in Candlestick Park, ABC’s cameras were rolling and their sportscasters reported the first news of the quake to the worried nation. Still today, the first clip and subsequent journalism that earned sports reporter Al Michaels an Emmy nomination for his hard news coverage can be viewed on Youtube. The Goodyear blimp, originally above the baseball stadium, ventured over the city to transfer images of the damage across the world. “We got almost to the Embarcadero, so close that I could see the collapsed section of the bridge with our high-powered lens,” recalled Jim Crayton, blimp pilot for 37 years. “It was eerie: All of downtown San Francisco was pitch-black except for the glow of the fires.” (Brinklow, et al.)

In the immediate aftermath, both San Franciscans in uniform and in Levi’s worked together to take care of their community. According to the California legislature’s disaster report, “The cities and communities of San Francisco, Oakland, Santa Cruz, Watsonville, and others threw their emergency agencies into the fight against further damage and loss of life. The cooperation between state, local, and federal officials was exemplary” (Roberti 1). Red Cross volunteers flocked to the emergency shelters that were hastily erected at Marina Middle School, the army barracks in the Presidio, a publishing house in the Tenderloin and aboard the USS Peleliu in the Bay (1989 Northern California Earthquake Appendix 6). Mayor Art Agnos has nothing but praise for the calm and composed attitude that San Franciscans exhibited in the wake of the disaster. “There was no rioting, no looting, no abuse of other people. One neighbor helping another. People were looking for others to help. As diverse a city as we are, we showed we were made of the all-American right stuff in one of the worst crises of the last 90 years.” (Brinklow, et. al)
The Loma Prieta disaster speaks volumes to the character of the City. During and after the quake, the city unified as it repaired its infrastructure, rebuilt homes, and returned to normalcy. The federal, state and city governments worked together to provide much-needed relief to the citizens and businesses of San Francisco. Only ten days after the tremor, the World Series resumed and announcer Al Michaels described how sudden the earthquake had come to this lively city: “the feeling of pure radiance was transformed into horror and grief and despair — in just fifteen seconds. And now on October 27, like a fighter who's taken a vicious blow to the stomach and has groggily arisen, this region moves on and moves ahead. … And while the mourning and the suffering and the aftereffects will continue, in about thirty minutes the plate umpire, Vic Voltaggio will say ‘Play Ball', and the players will play, the vendors will sell, the announcers will announce, the crowd will exhort. And for many of the six million people in this region, it will be like revisiting Fantasyland” (Marquez 1 and 2). The city’s recovery took much longer than ten days, but the prompt restart of the World Series was symbolic of the entire City. San Francisco would rebuild and recover and renew, just as it always has and just as it always will.
