Summary of Tables Explaining the JMA Seismic Intensity Scale

---

Shindo 0 – Imperceptible to people.

Shindo 1 – Felt slightly by some people keeping quiet in buildings.

Shindo 2 – Felt by many people keeping quiet in buildings.

Shindo 3 – Felt by most people in buildings.

Shindo 4

– Most people are startled.

– Hanging objects such as lamps swing significantly.

– Unstable ornaments may fall.

Shindo 5 Lower

– Many people are frightened and feel the need to hold onto something stable.

– Dishes in cupboards and items on bookshelves may fall.

– Unsecured furniture may move, and unstable furniture may topple over.

Shindo 5 Upper

– Many people find it difficult to walk without holding onto something stable

– Dishes in cupboards and items on bookshelves are more likely to fall.

– Unsecured furniture may topple over.

– Unreinforced concrete-block walls may collapse.

Shindo 6 Lower

– It is difficult to remain standing.

– Many unsecured furniture moves and may topple over.

– Doors may become wedged shut.

– Wall tiles and windows may sustain damage and fall.

– In wooden houses with low earthquake resistance, tiles may fall and buildings may lean or collapse.

Shindo 6 Upper

– It is impossible to move without crawling. People may be thrown through the air.

– Most unsecured furniture moves, and is more likely to topple over.

– Wooden houses with low earthquake resistance are more likely to lean or collapse.

– Large cracks may form, and large landslides and massif collapses may be seen.

Shindo 7

– Wooden houses with low earthquake resistance are even more likely to lean or collapse.

– Wooden houses with high earthquake resistance may lean in some cases.

– Reinforced-concrete buildings with low earthquake resistance are more likely to collapse

If you feel a tremor

Remain calm, and secure your personal safety

If you see/hear an Earthquake Early Warning

– Protect your head and shelter under a table

– Don’t rush outside

– Don’t worry about turning off the gas in the kitchen

– Panic leads to injury

– When driving a car, turn on your hazard lights, then slow down smoothly

– Keep away from gates, walls, vending machines and buildings

– Leave immediately to highland when a strong shake has been felt on the seashore

Make residences earthquake-resistant and fix furniture to prepare for earthquakes
