Seismic intensity refers to the strength of a tremor and is measured on an intensity scale of 10 levels, which range from 0 to 7, and include weak 5, strong 5, weak 6, and strong 6.
When an earthquake occurs, a tsunami can follow. Immediately seek safe shelter if you live near the sea, or the tremors continue for a long time.
Don't panic. First, use a cushion or other item to protect your head, then hide under a desk to keep safe.
Quickly move away from walls, vending machines, etc. and protect your head.
