AI Thread Summary
Unusual seismic activity on the U.S. East Coast, particularly before the August 23rd earthquake, remains largely undocumented. The earthquake, which registered a magnitude of 5.9, is notable as such events are rare in this region. The history of earthquakes in Virginia highlights that the last significant quake occurred in 1897, with a magnitude of 5.8. Other recorded seismic events include a 3.8 magnitude quake in 1959 and minor tremors in 1975. Resources such as the USGS website provide comprehensive data on recent and historical earthquakes, emphasizing that while the East Coast experiences fewer earthquakes than the West, they do occur. The geological history of the region spans millions of years, suggesting that while seismic activity is infrequent, it is not unprecedented.

I have been searching online trying to find information about any unusual/unexpected seismic activity on the east coast of U.S. before the earthquake struck on August 23rd. So far, I've not been able to find any articles about that subject. Has anyone seen any information on that topic? Earthquakes in that area are very rare, and I believe the August 23rd earthquake set a record, for that area, with a magnitute of 5.9. Because I live in a mid-atlantic state, and I felt last week's earthquake fairly strongly, I'm curious to know if any unusual activity had been recorded either days or weeks, etc., before the earthquake.
My thanks, in advance, to anyone who can enlighten me.

You can see from this map:

that while the earthquakes are much less common on the east coast than in the west, they do happen.

Here you go.

The history of earthquakes in Virginia.

http://www.virginiaplaces.org/geology/quake.html

The last "big one" in Virginia (about a 5.8 on the Richter scale) was on May 31, 1897, in Pearisburg, the county seat of Giles County. The judge in the courthouse adjourned a trial, jumped over the railing, and fled outside with everyone else as the courthouse rattled, brick walls cracked, and chimneys fell over. It was Virginia's most powerful recorded earthquake - but our recorded memory extend back only a few centuries, and the geologic history of the state extends back hundreds of millions of years. In 1959, Giles County was shaken again by a 3.8 temblor. More recently, windows were broken in a Veterans Day, 1975 earthquake in Blacksburg.

Thank you both so much for the links ! I appreciate the responses.
 
Hello, I’m currently writing a series of essays on Pangaea, continental drift, and Earth’s geological cycles. While working on my research, I’ve come across some inconsistencies in the existing theories — for example, why the main pressure seems to have been concentrated in the northern polar regions. So I’m curious: is there any data or evidence suggesting that an external cosmic body (an asteroid, comet, or another massive object) could have influenced Earth’s geology in the distant...
On August 10, 2025, there was a massive landslide on the eastern side of Tracy Arm fjord. Although some sources mention 1000 ft tsunami, that height represents the run-up on the sides of the fjord. Technically it was a seiche.
