Safety information
What to do in an earthquake
Three things first, then what to do before, during and after. From FEMA’s Ready.gov and the Great ShakeOut, the international earthquake drill.
For this reportEarthquake · Indonesia
Drop, cover, hold on
Drop to your hands and knees, cover your head and neck (under a sturdy table if one is near), and hold on until the shaking stops.
Ready.gov · ShakeOutStay where you are
Indoors, stay indoors and away from windows; do not run outside or stand in a doorway. In bed, stay there and cover your head with a pillow.
Ready.govBy the sea, go high after
If the shaking was strong or long and you are near the coast, move inland or uphill as soon as it stops. Do not wait for a warning.
Ready.gov · NWS
Before, during, after. Here it is “after”.
Before · Any day
Practise the gesture
Drop, cover and hold on, with everyone at home, so it comes without thinking.
Secure heavy things
Fix shelves and tall furniture to the wall; keep heavy and breakable objects low.
Keep a kit
Water, food, a torch, a whistle, a first-aid kit and your medicines.
Agree a contact
Someone far away whom everyone in the family calls or messages.
Ready.gov (FEMA)
During · While the ground shakes
Indoors
Drop, cover and hold on. Away from windows, mirrors and anything that can fall.
Outdoors
Move to an open place, away from buildings, trees, street lights and power lines.
Driving
Pull over away from bridges and overpasses, set the brake and stay in the car until it stops.
In a wheelchair
Lock the wheels, bend over and cover your head and neck.
Ready.gov (FEMA)
After · When the shaking stops
Expect aftershocks
They can come minutes or months later: drop, cover and hold on again.
Leave a damaged building
And do not go back in until it has been checked.
If you are trapped
Text, tap on a pipe or use a whistle: shouting tires you and raises dust.
Messages, not calls
Keep the lines free for emergencies and save your battery.
Ready.gov (FEMA)
Questions people ask
Should I stand in a doorway?
No. In modern buildings a doorway is no stronger than the rest, and the door can hit you. Drop, cover and hold on where you are. Source: Ready.gov (FEMA).
Should I run outside?
No. Most injuries happen to people moving during the shaking, hit by falling glass and masonry near the walls. Stay where you are until it stops. Source: Ready.gov (FEMA).
Can an earthquake cause a tsunami?
Yes, a strong earthquake under or near the sea can. If you are on the coast and the shaking was strong or long, go inland or uphill at once, without waiting for an official warning. Source: US National Weather Service.
