What to do when the ground shakes

Drop — Cover — Hold: let yourself down onto the floor, take cover under a sturdy table and hold on until the shaking stops. Do not run while the ground is still moving; do not use the lift; afterwards check the wiring, the gas pipes and the aftershock warnings. The full guide is on the explanation page.
