Intensity VI
Largest Earthquake in Florida
Regimentals and arms racks fell from walls in many barracks; everything in the rooms was moved; doors were sprung. Chimneys were thrown together causing fires. Neighboring houses clashed together, and people buried in the ruins cried for help. This event occurred during a "fearful" storm that was accompanied by violent thunder and lightning and raging seas. Possibly a hurricane.
