stay safe and may god bless you guys
Damage is occurring in north-central part of Japanese continent.
inland urban areas to east and west have not suffered major damage, so many Esports players, team facilities, etc. are not expected to be affected.
However, damage at epicenter is very large, even for Japanese example.
This seventh earthquake in Japan's history to have seismic intensity level 7 (level representing largest earthquake in Japan).
To answer your question, it is both.
Richter Scale is universal and is used as an indicator in Japan.
"seismic intensity level" in Japan measured by seismic intensity meters installed everywhere Japan, and is calculated by detailed calculations.
Since country prone to frequent earthquakes, seismic intensity is expressed as rough level with more physical feeling.
(Incidentally, minor seismic intensity standards probably exist in other countries around world.)
