Activity Ten

October 17 was the day of the third game of the 1989 World Series baseball championship held in San Francisco. Sixty-two thousand people were attending the game at Candlestick Part. The game was just started at 5.04 p.m. when a powerful earthquake struck. The magnitude 6.9 tremor caused approximately $6 billion in damage in San Francisco Bay Area. It was responsible for 63 deaths and almost 4000 injuries. However, the destruction was not as great as it might have been because of the unusual coincidence. Both of the teams were playing in the World Series – the San Francisco Giants and the Oakland Athletics – were from the bay area. Because of this, many people had left work early to attend the game or watch it at home with their families. Many others had stayed in the city after work, watching the game with their colleagues. Consequently, traffic was lighter than usual. No doubt this prevented many deaths. The earthquake was memorable for another reason as well. Due to the television coverage of the baseball game, it became the first major earthquake that was seen live by baseball lovers all over the country.
