Tsunamis are such uncommon events on the East Coast that the term itself is rarely used. Yet on November 18, 1929, the unthinkable occurred. A large scale earthquake rocked the eastern coast of North America at 5:00 p.m. In St. John’s, Newfoundland, although no serious damage was sustained, the quake shook buildings, broke dishes, and upset furniture. Most people did not know what and earthquake was and thought it was an explosion.
