An M6.1 earthquake occurred in the northern part of Ōsaka-fu (Osaka Prefecture) on June 18, 2018, with many areas in the Kinki region experiencing intense shaking. In Ōsaka City and Takatsuki City seismic intensity 6 lower was observed, resulting in 4 deaths, 15 people sustaining serious injuries, 419 people sustaining minor injuries, 10 completely destroyed residence, 181 partially destroyed residences, and 32,989 residences partially damaged (as of July 17, 2018). There were 339 cases of people being trapped in elevators. At most, approximately 1700 people were evacuated.
