In the import of a large magnitude quake, many important city facilities could be closed(a) down. For example, roadstead could be separated, thereby devising it onerous for pinch vehicles to get through. The 1989 quake in the San Francisco bay argona showed that freeway overpasses and bridges might collapse during a large shaker. Landslides often occur during earthquakes, thereby increasing the adventure of road closures in the argona. Telecommunications are also often shut down in the aftermath of a large eggshell earthquake. In particular, telephone lines may fall down as a result of the ground's shaking movements. Related to this, electric fountain may be shut off during a efficacious earthquake. Furthermore, water lines could be defiled by an earthquake, thereby windup off vital water supplies to the residents of the city. All of these factors make it hard for people to receive emergency jockstrap in a timely manner.
Another reason for this difficulty is the fact that emergency personnel in such agencies as the police department, fire department and the Red tangle are often overload in the wake of a largescale disaster. As noted by Virgin
umteen earthquake experts have referred to the possibility of a "seventy devil hour delay" in waiting for professional help to arrive. Of course, the city starts responding to the emergency immediately following a major(ip) earthquake. Efforts are made right away to help wound people and to reopen communications lines. The gas and water companies are trained to respond immediately to this type of crisis, and the volunteers of the Red Cross make their best effort to arrive at strike sites as soon as possible. In the wake of a major earthquake, the California Department of Transportation also goes immediately into action in order to help open roads which have been closed as a result of damage (Kimball, 1988, p. 55).
However, all of these efforts require time and it is impossible for these agencies to be all over at once. Because of this, people living in areas which are given up to earthquakes are warned that it might take up to seventy ii hours (or three old age) before help might arrive. In the rowing of Kimball: "Some help will undoubtedly be easy earlier than that, but we can't count on it. That's why individuals are urged to plan to be on their own for three days" (p. 56). This delay might be even longer in the miscue of an extremely large earthquake. If the damage is extensive end-to-end the city, the professional agencies will be especially preoccupied for a long period of time. In this type of worstcase scenario, Harris notes: "With water supplies and electrical power curtailed and with most communication lines cut, for several(prenominal) days after the quake coordination of emergency relief to the tens of thousands of hurt persons requiring immediate help will be painfully difficult" (Harris, 1990, p. 62). These statements provide ample evidence for the importance of the California assert University being selfreliant in its plans for dealing with a major earthquake in the future.
