[Godzilla2014/Monster-verse] In memory of San Francisco and Janjira, what other natural or unnatural accidents of history do you think were covering up Monsters?

We have mostly American records to go on.  Theories include:

1694: HMS Sussex destroyed by Kraken at Gibraltar.  

1776 - American East Coast - Area affected by wanderings of a squidlike kaiju Gezora, emitting cold for several years.  This has an impact on the American Revolution. 

1865 - Steamship Sultana explodes trying to evade "White River Monster", form of deep sea kaiju out of its natural environment in the Mississippi River.  Accounts differ if the kaiju attacked, or its presence inspired the crew to overtax the boilers out of desperation. 

1874 Plague of Locusts in American MidWest - Actually a secondary result of a flying giant Praying Mantis.  Sightings of the Mantis are associated with native American 'Thunderbird' legends. 

1906 San Francisco 'Earthquake'.  Giant Ants undermined the entire city. 

1917 - Halifax Explosion. Only King Ghidorah attack documented in North America.

1940 Tacoma Narrows Bridge - Rodan overflight.  Considered unintentional. 

1947 - Monte Serrat Funicular accident attributed to presence of a giant anaconda. 

1975 Loss of the Edmund Fitzgerald on Lake Superior from irradiated 7 armed giant octopus.  The octopus was successful destroyed afterwards with assistance from Dr Benton Quest. 

1986 Chernobyl - Unclear, but competing theories point to major kaiju mishap.  Continued quarantine of area suggests threat was only contained, not neutralized.

1998 - Cavalese Cable Car accident - A US aircraft may have been flying recklessly in pursuit of a flying kaiju. NATO protocols for these events have been revised, and training intensified. 

Contrary to popular belief, an investigations of the Atlantic coast off the southeastern United States in the late 1970s did not yield any evidence of kaiju activity to explain the 'Bermuda Triangle'.   Dr Jon Quest's team is requesting funding to investigate with modern equipment.
