For instance have an out of state family member who everyone will contact once they have gotten to safety. Don't try to move indoors or outdoors, objects may fall on you. If you are in a car, stop the vehicle as soon as possible. Try to stop in a clear area away from bridges, trees, power lines, etc. Stay in the vehicle.
Aftershocks can occur from hours to months after the initial earthquake.
Help injured or trapped persons. Be especially aware of those who may not be able to help themselves such as small children, the elderly and those with disabilities. Listen to the radio for up to the minute information on the disaster. Stay out of damaged buildings until authorities say it is safe to return. Turn off gas, electricity and water if there is a problem.
