AI Thread Summary
A magnitude 7.5 earthquake occurred in the Southern Drake Passage on August 22, 2025, at a depth of 10.8 km. The epicenter was located at coordinates 60.186°S and 61.821°W. The moment tensor solution indicated significant tectonic activity, with a best double couple moment of 2.0 x 10^20 Nm. Additionally, a separate 5.3 magnitude earthquake was reported near New Zealand, approximately 800 km NNE of Auckland, shortly after the Drake Passage event. The seismic activity in these regions highlights ongoing geological processes in the area.

New Zealand had a 5.3 at 10km depth about 800 km NNE of Auckland at 09:33:35.9 UTC. Did you "see" that?

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...
