What the record says
NCEI’s account, from the sources it cites.
Reference #414:
1965, April 20, 8:42. There was an earthquake, which did light damage to buildings at Shimizu, Shizuoka Prefecture. One person died and four were injured in Aichi Prefecture. It was felt strongly at Yokohama and more northern regions. It shifted rails. Pits appeared in the highway. Soon afterwards, the tide gauges at Tagono'ura and Uchi'ura registered oscillations in level with a height of up to 10 cm and a period of 5 + minutes. Apparently, these were seiches of seismic origin.
