Nov. 20, 1933: A M7.3 earthquake struck offshore Baffin Island, #Canada.
This is the largest known #earthquake along the passive margin (east/north coasts) of #NorthAmerica and the largest (known) earthquake north of the Arctic Circle.

A few years ago I made this flow chart of which Mastodon posts end up in which timelines!

So, you can see how each instance will have a different local timeline, and even a slightly different federated timeline - and you can see why the federated timeline moves so much faster than the local one, too.

This is why it's important to boost good posts and use hashtags - the fediverse is fragmented and harder to search by nature.

There's a bit of a storm happening around the criteria for joining http://fediscience.org - the Mastodon instance for scientists, on which I'm hosted.

It's been noted that the requirement to be a publishing scientist (who has published in the past 5 years) will exclude many junior scientists, retired sciences, and those who have maybe switched to teaching.

I agree with these concerns and wonder if the criteria can be changed to be more inclusive?

Through the burning of fossil fuels, humans have released more carbon into the atmosphere than is contained in all of the plants currently living on Earth.

More than half of this has occurred since 1990.

We are transforming the Earth and the atmosphere on a truly massive scale.

Reforestation, and other natural solutions, will never match the scale of the problem without substantial emissions reductions.

Tectonic stress change due to the 2011 Tohoku earthquake inferred from long-term CMT data of regular earthquakes

It's hard to overstate how much fuel the failure of the DOJ to hold the former WH occupant accountable for his role in the Jan. 6 insurrection & theft of classified documents (among others) causes the MAGA crowd to aggressively assert he's done nothing wrong. That is: No charges=No Crimes.

Testing out this platform. Do video clips of lava work? Here is one I shot from Iceland last year. Is it a still or video?

My most well known photo from the field, and well timed being very nearly the anniversary of the 2016 Kaikoura Earthquake sequence. This is the "Wall of Waiau" on the Leader fault. This scarp is actually a bit of a quirk of nature, no prior rupture here and effective localised normal movement due to topography on an oblique thrust and right lateral fault.
