At Sakata and Utokawara, the homes were not destroyed, but some of them were damaged. In the Shonai region, in relation to the total number of structures, the destruction was very small. At Matsugasaki and other villages near Niigata, liquescence of the ground was observed. The zone of destruction and damage adjoined the coast. There was almost no destruction at a distance from the coastal zone, although the ground cracked. The tremors were rather strong on Sado Island; homes were destroyed at different points. On Hokkaido Island, the intensity of the earthquake was probably small, since no damage was reported.
