A JW writes as proof that 1914 is key...
The NewEncyclopædiaBritannica (1987) lists 63 “Major historical earthquakes” spanning the past 1,700 years. Of this total, 27, or 43 percent, have struck since 1914. The book TerraNonFirma, by Professors Gere and Shah, has a list covering a longer period. Of the total “significant” earthquakes in that list, 54 percent have taken place since 1914. Even granting that records from past centuries are incomplete, we cannot escape the conclusion that in our time mankind has been greatly affected by earthquakes.
Does anyone have access to the The NewEncyclopædiaBritannica (1987) or info that would either support or refute the above allegations.
