A magnitude 3.9 earthquake rumbled beneath the Atlantic Ocean seafloor off the East Coast of the United States today, 30-Nov-2010.
The earthquake occurred at a depth of 6.6 km, only about 100 miles off the coast of New Jersey.
The eyebrow raising fact of this earthquake however, is its location. That is, right on the edge of the continental shelf where the seafloor drops from a depth of 500 feet all the way down a steep cliff to about 7,000 feet before gradually dropping further to depths as deep as 20,000 feet.
The location of the earthquake, although 4 miles below the surface (about 21,000 feet), is centered literally right on the top edge of the 7,000 foot cliff.
It is unimaginable to think about the consequences if part of the 7,000 foot cliff were to crack and fall away to the seafloor.
There is no indication that this is a current possibility, simply an observation based on the location coupled with the fact that we don’t often see earthquakes in this general location.
(stay tuned – more maps and data forthcoming…
