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.

JISHINDESU catalogue organised from JMA and P2PQuake data. Times use JST. Points are reported epicentres and observations, not simulated wave propagation.
How to read the record for April 18, 2025
The JISHINDESU catalogue contains 31 earthquakes for this day; 31 reached maximum Shindo 1 or higher. The day's highest Shindo was 5−, and its largest reported magnitude was M5.0.

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.
Shindo and magnitude explained →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.
