Largest Earthquake In 50 Years Hits Queensland: Here’s What Happened.
OzGeology.


I received a phone call from a woman I know in Hervey Bay, 120 km from the epicentre, asking if I believed in earthquakes, or if they are caused by the devil. I think that demonstrates the stability of the Australian continent.

Because the USGS cannot give accurate info for events well outside their network coverage.
They only have 1 sensor in QLD ( Charters Towers) and it isnt a geophone and is far from the event, so it wont respond well to local regional events

It was a ML5.6 as per the Geoscience Australia info

Thread 'Landslide, tsunami, seiche in Tracy Arm fjord, Alaska - 10 August 2025'

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.

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...
