JISHINDESU catalogue organised from JMA and P2PQuake data. Times use JST. Points are reported epicentres and observations, not simulated wave propagation.

Reading the daily record

How to read the record for May 22, 2023

01

Catalogue time, not a wave simulation

The replay reveals reports at their recorded JST origin times. Station dots show observed Shindo, but the moment they appear is not a measured seismic-wave arrival time.

02

Shindo and magnitude measure different things

Magnitude describes the earthquake at its source; Shindo describes shaking at each station. One earthquake can therefore produce different Shindo readings by location.

03

A record can be updated later

Follow-up bulletins and corrections for the same earthquake are consolidated into one record. Each report page shows the current values and any available revision history.
