Watanave Hidenori and his team at the University of Tokyo use social media, satellite images and other digital resources to research and map wars and natural disasters, partly as a way of rebooting and preserving their memory. In addition to the 1923 quake, the team has produced digital archives of the Hiroshima and Nagasaki nuclear bombings, and the 2011 Tohoku (Great East Japan) tsunami, and they currently track war damage in Ukraine, following Russia's invasion in 2022. Questions by Tristan Grunow, Laura Hein, and David McNeill. Questions were posed in English, to which Watanave responded in Japanese. Answers have been translated from Japanese, and can be found after the English interview.
