Understanding the JMA Seismic Intensity Scale (Shindo)

Unlike the Richter scale (Magnitude), which measures the total energy released by an earthquake, the JMA Seismic Intensity Scale (Shindo) measures the degree of shaking at a specific location. This is often more relevant for understanding the impact on your immediate area.

Shindo 1–2

Felt slightly by some people in quiet buildings. Hanging objects may swing slightly.

Shindo 3–4

Felt by most people. Dishes and objects in cupboards rattle. Sleeping people awake. Unstable objects may fall.

Shindo 5 Lower/Upper

Many people find it hard to move. Dishes and books fall. Concrete block walls may collapse. Heavy furniture moves or topples.

Shindo 6 & 7

Impossible to remain standing. Major structural damage. Wooden houses may collapse. Large cracks in the ground.

Earthquake Safety & Preparedness

During an Earthquake

  • Drop, Cover, and Hold On: Get under a sturdy desk or table.
  • Stay away from glass, windows, and heavy furniture.
  • If outside, move to an open area away from buildings and power lines.
  • Do not rush for the exit if you are in a crowded place.

After Shaking Stops

  • Check for injuries and apply first aid.
  • Turn off gas valves and unplug appliances.
  • Open doors and windows to secure an exit route.
  • Evacuate if there is a tsunami warning or fire risk.

Emergency Numbers

  • Police110
  • Fire / Ambulance119
  • Coast Guard118
  • Tip: Most emergency operators in Japan can connect you to an English interpreter.

Frequently asked questions

What is the Shindo scale in Japan?

The JMA Seismic Intensity Scale (Shindo) measures the degree of shaking at a specific location, ranging from 0 to 7. Unlike the Richter scale (Magnitude) which measures total energy released, Shindo is more relevant for understanding local impact. Shindo 1-2 is barely felt, Shindo 3-4 rattles objects, Shindo 5 makes movement difficult, and Shindo 6-7 causes major structural damage.

What should I do during an earthquake in Japan?

Drop, Cover, and Hold On: Get under a sturdy desk or table. Stay away from glass, windows, and heavy furniture. If outside, move to an open area away from buildings and power lines. Do not rush for the exit if in a crowded place.

What are the emergency numbers in Japan?

Police: 110, Fire/Ambulance: 119, Coast Guard: 118. Most emergency operators in Japan can connect you to an English interpreter if needed.

Where can I get official earthquake information for Japan?
