About 400 people were brought together in some 20 positions throughout Stanford to carry out an earthquake drill (演习).
The earthquake drill was a year in the planning. It included both Stanford University and Stanford Medicine emergency operation (行动) centers. The university frequently practices emergency plans, but this drill was different from the earlier ones.
This drill asked the university to consider how everyone in the school took on duty after an earthquake. How would Stanford continue to feed thousands of people and take action in the face of damage to the university? How would it answer the thousands of people who called the university and who were worried about their loved ones?
"We wanted to create an experience centering mainly on recovery (恢 复), rather than the immediate life safety you would experience right after an earthquake," said Keith Perry, university emergency manager and training and communications manager for Environmental Health and Safety.
The actions of all the people surprised Police Chief Laura Wilson, whose job was to manage the many people in the main EOC in the Faculty Club. "I really wanted to express my thanks to the teamwork of everyone," she said. "My job was made much easier by the fact that people practice and know what to do. This is a finely honed (打磨) machine."
Peter is an experienced worker of Stanford Medicine EOC. He believes that with each drill carried out, people get better at protecting public safety, repairing the damage to the university and quickly returning the university to normal teaching and researching activities. "I think everyone learned a lot today," he said.
