New ad dropped:
Trump standing looking indifferent while a man possibly dies next to him. A few bald men hold his legs up in the air as if he’s going to take a giant shit or give birth. Sure, maybe it’s to help the blood flow to his head faster. Either way, graphic reads “Trump care, concepts of a plan since 2015.”

photographic view featuring the tower of the building of the Institute of Geosciences in Jena towards west. The institute is located on a Pleistocene strath terrace of the Saale river, c. 50 m above the city centre (feturing some skyscrapers in the middle of the photo). The forested plateau in the background of the photo is formed by mesas exposing Middle Triassic strata ('Muschelkalk'). Jena is a thriving university town offering very high living standards and a cool place to be ;-)

Fish in the forest, seaweed in trees?
Yes - 13 years ago tonight, the M7.8 #HaidaGwaii earthquake generated the world's largest #tsunami of 2012. Runup to 13m in some inlets left seaweed in trees and fish in the forest. If you are near water and feel long and strong shaking, go to high ground.
🧪🌊⚒️
A photo of seaweed in trees and a GPS unit to measure the height above sea level. The seaweed in the trees was deposited by the October 27th, 2012 tsunami generated by an offshore M7.8 earthquake. GSC photo.

Tuesday's 530am #earthquake was a well-timed follow-up to #ShakeOutBC. The early timing and quiet schools resulted in the event being nicely recorded on all #SchoolShake instruments. If you felt it, you can still report it here www.earthquakescanada.nrcan.gc.ca/dyfi-lavr/fo...

When #seismology meets #meteorology!
Ground shaking across #VancouverIsland is ramping up (but not felt) as the remnants of Tyhpoon Nakri approach the west coast.
The ground shaking started increasing just after midnight Pacific time (07:00 UTC on this figure) Oct. 17, as the storm gets closer.

Why are "nation building projects" always things that accelerate the destruction of the planet largely to the benefit of multinational corporations, and never things that would benefit millions of Canadians like, say, high speed passenger rail?

It’s been more than 20 years since I installed the 1st school-based weather station at Strawberry Vale Elementary on March 11, 2005. Now, the project is at a critical juncture. Do I shut it down, or do I try to reinvigorate it? Decision day is Sept. 30, 2025.

This one shows a different angle of the mountain that the landslide originated from, and also the water in the fjord that is now filled with debris. The terminus of the glacier is also visible, and is covered with rock and debris. Picture taken by pilot Jacek Maselko.
