Background and detail
Event Details. The earthquake occurred on June 15, 1896. Sources report conflicting times, with one stating 7:32 am and another 19:32 local time. It generated two tsunami waves that struck the coast, reaching heights of 24 meters at Yoshihama. The disaster resulted in the destruction of about 9,000 to 10,000 homes and caused at least 22,000 deaths, with 18,158 recorded in Iwate alone.
Context and Aftermath. Communities along the Sanriku coast were celebrating a Shinto holiday and the return of soldiers from the First Sino-Japanese War when the disaster struck. Preventive coastal measures were not implemented until after another tsunami in 1933, highlighting the lack of immediate mitigation following the 1896 event.
