We conducted a lightning damage survey in Tohoku region from 2010 to 2019, and classified the damaged items by infrastructure installation. Among them, explosive damages such as windowpanes and shoji (a sliding paper door) of historical buildings, and those of walls and pillars of ordinary houses have been confirmed. As explosive damages can have a significant impact on buildings, we have investigated the mechanism of damage occurrence and clarified the relationship between explosive damages and the properties of lightning. In addition we considered the effects of explosive damages on the human body.
