NYC Earthquake

NYC Earthquake

RE: NYC Earthquake

I felt it at my desk in Rhode Island.

RE: NYC Earthquake

I hope the USS New Jersey is ok. She's up on blocks in a drydock in the Philadelphia Navy Yard. It would be a sad day for naval heritage if she took damage during their preservation efforts.

RE: NYC Earthquake

I saw an interview with a librarian near the epicenter in NJ, a few books wiggled but none fell off their shelf.

Epic engineering disaster.

RE: NYC Earthquake

Yeah. Questionable what forum to post this in as it hasn't really been an engineering failure or a disaster. Nevertheless it is a reminder to locals and also to engineers in general that these events still will occur even in areas of low seismic activity. Maybe better in the 'Seismology engineering' forum but who looks there regularly?

My city that I call home had a seismic wake up call of similar magnitude in 2021. Lots of shocked and curious people, a few collapse masonry walls, but nothing serious. But it is still a wake up call.

One day somewhere in the globe might even have a 'big one' in a populated area that isn't known from seismic activity. The probability chart of seismic events has a long tail.

People have short memories. Geology doesn't. A once in a 10,000 year seismic event wouldn't be pretty in a populated area.

RE: NYC Earthquake

They've finally released some photos of the damage from the New Jersey/New York earthquake and this one appears to show the most damage that I've seen so far:

I sleep fairly well in a building that's built within the remains of a volcano that hasn't erupted for around 340 million years. I worry more about a loose tile falling off the roof as I walk out the door.

340 million years. I can image a great sleep.

I had some fun in Geology undergrad rebutting a journal article from one of my professors. His thesis was essentially that there was a ~1/3000 year return period of serious volcanic activity in the western area of my state and that we should prepare for it. My paper was agreeing with his recurrence assessment, however disputing the preparation advice on the basis that serious preparation was uneconomic and wasn't a significant risk to life. Engineered solutions were impossible or impractical and lack of a 'surprise' factor meant that life loss was unlikely.

Volcanic activity normally gives more warning so lives are generally less at risk. Seismic activity is really quite unpredictable. And while you shouldn't personally lose sleep over the 'big one', prudent engineering and insurance should consider it.

RE: NYC Earthquake

I live in northeast PA about 45 NW of the Lebanon NJ; didn't feel a thing, although some people in my area did.

RE: NYC Earthquake

I grew up just outside of NYC. We had small earthquakes, tornadoes, and floods every few years.
