A reconnaissance of steel school gymnasium damaged by the earthquake off the coast of Fukushima Prefecture on February 13, 2021 has been conducted. These gymnasiums were also damaged in the 2011 Tohoku earthquake, and have been repaired or strengthened. In the two gymnasiums, severe damage to non-structural components occurred again.
