Curious times - the Earth Shattering Ka-Boom

| No Comments

Strange phenomena around the USA in the last two months - a tranche of clickable headlines:

Very curious. This next item I would take with a grain of salt as there are no links to source materials but here we go.
From Above Top Secret (this post is from 2013 so not related to the current spate of booms):

"Canon Booms" Heard And Felt For 2-3 Years Prior To 1811-1812 New Madrid Earthquakes
There has been speculation recently that the loud boom sounds and vibrations being reported around the USA could be related to the New Madrid fault zone. So I decided to look at some of the accounts from the survivors of the 1811-1812 New Madrid series of earthquakes, which supposedly included 4 mega quakes, 3 major quakes, and thousands of minor quakes.

What I found is that several people wrote accounts of hearing what they described as loud booms that sounded like cannon blasts for up to 2-3 years (depending on the location) before the earthquakes happened. The descriptions talk about these loud booms often being accompanied by vibration and shaking sensations. The accounts describe these loud "cannon booms" as happening also right before the earthquakes happened.

They describe hearing the same loud booms they had been hearing for up to 3 years right before the big earthquakes hit. The only difference was that the sound booms right before the quakes hit were louder than the previous booms that had been happening for the previous 2-3 years.

New Madrid? From InfoGalactic:

1811–12 New Madrid earthquakes
The 1811–12 New Madrid earthquakes were an intense intraplate earthquake series beginning with an initial earthquake of moment magnitude (7.5 -7.9) on December 16, 1811 followed by a moment magnitude 7.4 aftershock on the same day. They remain the most powerful earthquakes to hit the contiguous United States east of the Rocky Mountains in recorded history. They, as well as the seismic zone of their occurrence, were named for the Mississippi River town of New Madrid, then part of the Louisiana Territory, now within Missouri.

There are estimates that the earthquakes were felt strongly over roughly 130,000 square kilometers (50,000 sq mi), and moderately across nearly 3 million square kilometers (1 million square miles). The 1906 San Francisco earthquake, by comparison, was felt moderately over roughly 16,000 km2 (6,200 sq mi).

Interesting times...
