After an earthquake it takes about 3x as long to get from point A to B.
This is due to: traffic, lack of transportation, road hazards
Be prepared for aftershocks in the first hours, days and weeks after the quake.
Open closet and cupboard doors cautiously.
If (and ONLY if) you smell gas or hear blowing or hissing noise, open a window and quickly leave the building. Turn off the gas at the outside main valve if you can.
Call the gas company from a neighbor's home. If you turn off the gas for any reason, it should be turned back on by a professional.
If you see sparks or broken or frayed wires, or if you smell hot insulation, turn off the electricity at the main fuse box or circuit breaker.
If you have to step in water to get to the fuse box or circuit breaker, call an electrician first for advice.
If you suspect sewage lines are damaged, avoid using toilets and call a plumber.
If water pipes are damaged, contact the water company and avoid using tap water.
