Are Two New Zealand Earthquakes a PM Alert from @StevieNZ?

AI Thread Summary
A recent earthquake measuring 5.1 magnitude occurred in central Cook Strait, while a stronger event of 6.1 magnitude was reported south of the South Island. The USGS confirmed the latter event, which produced a notable T-phase wave. Despite these occurrences, the year has been relatively quiet for significant earthquakes, with only four events recorded in the M7.0 to 7.9 category, significantly lower than the average of twelve by September. This trend marks one of the lowest activity levels seen in recent years. Additionally, a significant 7.1 magnitude earthquake struck near Puebla, Mexico, coinciding with earthquake readiness drills in Mexico City, commemorating the anniversary of a devastating quake in 1985.

from a PM alert to me from @StevieNZ

http://www.geonet.org.nz/earthquake/2017p708412 - felt that a few mins ago

yup well that one was central Cook Str. 5.1 is a respectable event :)
I didn't record it or the signal was lost in the overpowering one from S of the South Island
which the USGS put at 6.1

Odd, because https://www.stuff.co.nz/national/nz-earthquake/97046815/earthquake-hits-south-of-invercargill earlier before

I recorded it quite well
the bottom event on the trace

https://www.physicsforums.com/attachments/zhi-gif.211389/It has produced a really strong T-phase wave
the burst of signal at ~ 02:07UT ( bottom trace)

it's actually been a really quiet year this year
average are well down for the M7.0 to 7.9 events

so far this year there have only been 4 events in that category
there avg up till around September would normally be around 12 with around 18 as a yearly avg
I haven't seen it this low for a really long timeDave

The U.S. Geological Survey said the magnitude 7.1 quake hit at 1:14 p.m. (2:15 p.m. EDT) and was centered near the Puebla state town of Raboso, about 76 miles (123 kilometers) southeast of Mexico City.

Earlier in the day, workplaces across Mexico City held earthquake readiness drills on the anniversary of the 1985 quake, a magnitude 8.0 shake that killed thousands of people and devastated large parts of the capital.

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.
