New Jersey earthquake~~~~>

I see that there was an earthquake in New Jersey, here's what the USGS had to say about it:

The April 5, 2024, M 4.8 earthquake near Whitehouse Station, New Jersey, occurred as a result of oblique reverse and strike-slip faulting at shallow depths in the crust. Although this event did not occur near a plate boundary, such “intraplate” earthquakes can and do occur. While this earthquake is relatively small globally, earthquakes of this magnitude are commonly widely felt in the eastern United States because of efficient seismic wave propagation in the region.

Earthquakes in the eastern US are infrequent but not unexpected. Since 1950, 40 other earthquakes of magnitude 3 and larger have occurred within 250 km of today’s earthquake. In that time range, the April 5, 2024, earthquake is the largest. Within 500 km of the April 5th earthquake, 13 earthquakes M 4.5 and larger have been recorded since 1950, the largest being the August 23, 2011, M 5.8 Mineral Virginia earthquake which caused substantial damage and was felt throughout the eastern US. The April 5, 2024, earthquake occurred in a region where faults have been previously identified and may be reactivated at any time.

A Mag 4.8 is pretty stiff, I can see how it would be very unnerving, especially because they're very infrequent in that area. Even in California, that's one that'll get your heart racing. I hope anyone in that area isn't too traumatized by it

Be safe y'all!

First time that I heard so big earthquake on the east side, generally we heard that occurs on west coast, in the vicinity of California, or California.

Be careful

Mon ami, the scariest ones I've ever heard of was the 1811-12 New Madrid:

The 1811–1812 New Madrid earthquakes were a series of intense intraplate earthquakes beginning with an initial earthquake of moment magnitude 7.2–8.2 on December 16, 1811, followed by a moment magnitude 7.4 aftershock on the same day. Two additional earthquakes of similar magnitude followed in January and February 1812. They remain the most powerful earthquakes to hit the contiguous United States east of the Rocky Mountains in recorded history. The earthquakes, 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 and now within the U.S. state of Missouri.

It literally made the Mississippi River run backward for a while, err-ahhh, no thanks!

My friend, I learn again with you, so the two coast of your country are seismically active zone.  The earthquake of San Francisco was in my mind one of the biggest in history. I know nothing 😔
