Remain Calm and Ensure Your Own Safety!
When a strong tremor is expected to occur, an earthquake early warning announcement to “Prepare for powerful tremors” is broadcast via the TV, radio and mobile phones.
After a warning is issued, it may take a few seconds or more before the strong tremors begin. Use this time to ensure your personal protection (particularly your head).
*Since warnings are issued after seismic waves are detected, areas close to the earthquake epicenter may begin experiencing strong tremors before the warning is issued.
