New Jersey Sinking - Boo Hoo


Interesting article on sea level change, and the sinking of the east coast. My goodness, we started warming the earth significantly the very first day of the steam engine! Whatever are we to do?

There is also a longer cycle of sinking due to the passive margin cooling. That would be seen in much older sediments. Reminds me of the long-term sinking around Hamilton due to the fault motions.

What is the estimated rate of sinking in Hamilton petri dish?

The Hamilton Jelly Bowl 'sinks' a couple of cm per century relative to the lake, due to glacial rebound at Kingston. Actually, the lake fills.

The geological sinking is probably a lot less, and occurs when there is a large earthquake, perhaps every few hundred years.
