What the record says

NCEI’s account, from the sources it cites.

Reference #1136 says, Area of destruction small (200 sq. mi.) but damage very heavy within that area. Fires in wooden houses spread, for a total of 3,960 burned houses in addition to the 63,000 that were destroyed by the earthquake. The intensity of the earthquake in the epicentral area on the Fukui alluvial plain was the highest value on the (Japan) Central Meteorological Observatory's scale (VI--total destruction, which would probably equal to IX in MM). No tsunamis resulted. 5131 killed, 11,000 injured, 63035 houses destroyed, 18543 houses damaged, 3960 houses burned.

5131 deaths, $1000 million damage. (reference #1250)
