How to read these observations
Shindo describes shaking at the measurement point. Magnitude describes the size of the whole earthquake. Nearby stations can record different Shindo values for the same event, and a station reading is not an exact measurement at your home.
Understanding the Shindo scale →Sources and catalogue coverage
We display observations stored by JISHINDESU from JMA and P2PQuake reports. The history may be incomplete and reports may be revised. Maximum Shindo here refers to available records, not the station’s entire history.
