Are We in for a Double M 7.4 Earthquake in El Salvador?

AI Thread Summary
A double seismic event occurred offshore El Salvador, initially reported as two magnitude 7.4 earthquakes occurring just one minute apart. However, one of the events was later removed from the reports, leading to a downgrade of the remaining event to magnitude 7.3. Following this, a magnitude 6.1 earthquake was recorded by the USGS, while GNS reported it as magnitude 6.5. This latter quake arrived first and contained signals from the earlier 7.3 event, complicating the analysis of the seismic activity.

well this turned into a tricky situation
After the M 7.3 ( downgraded from 7.4), Central America there was a M 6.1 (USGS), M6.5(GNS Geological and Nuclear Sciences, NZ)
which because it was closer to me arrived first. And buried in its signal is the P and S arrivals of the M7.3

Thread 'Could an external cosmic body have influenced Earth’s geology?'

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...

Thread 'The Secrets of Prof. Verschure's Rosetta Stones'

(Edit: since the thread title was changed, this first sentence is too cryptic: the original title referred to a Tool song....) Besides being a favorite song by a favorite band, the thread title is a straightforward play on words. This summer, as a present to myself for being promoted, I purchased a collection of thin sections that I believe comprise the research materials of Prof. Rob Verschure, who at the time was faculty in the Geological Institute in Amsterdam. What changed this...
