One fact is that, for these earthquakes with maximum intensity of X or greater (X, XI, XII), the USGS shake map often underestimated the maximum intensity, with many of them giving a maximum shaking intensity of around IX, few of them X.
By the way, for what I known, the 1920 Haiyuan earthquake has maximum intensity of XII (very rare), the 1976 Tangshan earthquake and 2008 Sichuan earthquake has maximum intensity of XI, and so on.
Oh the map? Well it’s “open” for the public but the website doesn’t work, but the SASMEX which is the seismologist department in Mexico releases videos of it
@@Shindo7earthquake I see. I would suggest to do the 2020 Oaxaca Mexico earthquake, which has slightly stronger magnitude and stronger shaking intensity than this one (2018 Oaxaca Mexico earthquake).
