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?
