According to the Department of Conservation scientists, California will likely experience a major earthquake in the coming years. People should be prepared to fend for themselves for at least three days after an earthquake as essential services may be disrupted. It is important to have emergency supplies like food, water, medicine and tools ready. During an earthquake, move away from windows, glass and heavy objects and get under a table. After an earthquake, check for fires and gas leaks, use the phone only for emergencies, and watch out for aftershocks.
