35+ years ago, I was freshly out of High School and the discussion came up about an increase in earthquakes equating to the "Time of the End". It was just a High School Education and having the ownership and possession of a National Geographic Atlas of Maps that included a map of the Ring of Fire, maps of the earths' plates, and areas of high plate shift and regions of high expectation of earth quakes. There was a major earth quake and Brother "Has too much Faith in the Governing Body" mentioned this as a precursor of the Great Tribulation. I said, Brother "Bama Much Faith", this is a region prone to earth quakes because they are located on top of a plate. I further mentioned there were about 5000 earthquakes a year. He debated with me about how many EQ's there were and I humbly remained silent.
About a year later, the explanation from the WTBTS was that earthquakes would be effecting more persons than ever in history not necessarily increasing in numbers. Which is a safe bet. Just thought this was interesting.
