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.
