What’s shakin?
This last weekend the Sunday School Lesson covered the material in 3rd Nephi 9 about the events that happened in the Western Hemisphere at the time of the crucifixion. While reading the descriptions of the changes to the land, the thought came to me that it sounded like a massive earthquake. I wondered if there might be any geologic evidence for any large earthquakes on the North American continent, so I did a Google search and came up with some interesting information, which I’ve blended here:
The most widely felt earthquakes in the recorded history of North America occurred in 1811-1812 near New Madrid, Missouri. (About 400 miles south of Independence.) A great earthquake, estimated at magnitude 8, occurred on the morning of December 16, 1811. Another occurred on January 23, 1812, and a third, the strongest, on February 7, 1812.
The quakes were felt across two-thirds of the United States and in Canada. They changed the elevation of land by as much as 20 feet. Large areas sank into the earth, fissures opened, lakes permanently drained, new lakes were formed and forests were destroyed over an area of 150,000 acres (600 km²). Many houses at New Madrid were thrown down. “Houses, gardens, and fields were swallowed up”. This temblors caused permanent changes in the course of the Mississippi River, giving the illusion that it was flowing backward. The crew of the New Orleans (the first steamboat on the Mississippi, which was on her maiden voyage) reported mooring to an island only to awake in the morning to find that the island had disappeared. Along the Tennessee/Arkansas state line, geological features are still present almost 200 years after the events, showing the former course of the river.
Survivors reported that the earthquakes caused cracks to open in the earth’s surface, the ground to roll in visible waves, and large areas of land to sink or rise. Damage was reported as far away as Charleston, South Carolina, and Washington, D.C. In Bootheel Mo, the land was so damaged that it was even unfit for farming for many years. It was the largest burst of seismic energy east of the Rocky Mountains in the history of the United States and was several times larger than the San Francisco quake of 1906.
Several lines of research suggest that the catastrophic quakes happen in the New Madrid region every 500-600 years. A 7.5 or greater quake, happens every 200- 300 years.
Obviously, these facts are not conclusive evidence that an earthquake did occur around Jackson County 1975 years ago, but to my way of thinking they increase the possibility, as seismologists believe the area has been seismically active (and in the same place) for 750 million years.
