As Stephen Schwartz points out on Twitter, today is the 51st anniversary of the United States' largest ever underground nuclear test - about 5 Megatons at Amchitka Island, Alaska.

Wondering what’s #shaking in your part of the world?
See the live seismograms that record #earthquakes (near and far), #windstorms and any other event that might cause the ground to shake (could be a moose walking by).

Have just realised that #academics can use @ORCID_Org to
#verify themselves.

Just include your full mastodon link (like this: mas.to/@marekmcgann) in the "Websites and Social Links" section in ORCID, then include link to your ORCID record in your Mastodon profile.

Hurray for distributed digital identities!

Hello! As an #introduction to me, I am a #geologist who studies #topography and how it reflects active #tectonics with a special focus on bedrock #rivers.

I am passionate about #openaccess publishing and #opensource software development for geoscientists. I'm looking to connect with other twitter refugees and new folks as well!

Early reports from multiple agencies indicate a shallow #earthquake occurred in #Italy, M5.5-6.0, widely felt. Approximate location is shown on a #tectonic map from Trippetta et al. 2019 with a yellow blob.

Magnitude 5.7 #earthquake in Adriatic Sea, East of Central #Italy about 15 minutes ago (2022-11-09 06:07:26) Data from station MN.CUC (Castrocucco, Italy) courtesy of INGV, Italy (emsc-csem.org/Earthquake/earth)

@henry yes!
i have been using hashtags like and

it seems like they may need to propagate which seems to take some time... but others have seen my toots where i used those tags and they are on a different server.

tho i am still on my steep learning curve!

Tuesday update on the #mastodon growth. 135k (!!) users join yesterday. Also, I'm zooming out the plot to see the evolution in the number of new users through the last year. I'm going to need a logarithm scale pretty soon 😎

now that i am following more , and those tooters are following more tooters, there are lots more on my .

totes! rather, toots!

I love the graphic on the cover of this 1977 Bulletin from the Oregon Dept. of #Geology on North American #Ophiolites.

for the M 7.6 (likely) subduction zone in on 19 Sept 2022

catching up on reports that happened after my website went down

probably triggered landslides/induced liquefaction

Hi! I’m an environmental geoscientist and educator who believes passionately that meaningful place-based geoscience education can change the world.
I share about science, education, equity and my family. #Introduction #Geoscience #Science

Did you miss last Friday's webinar with presentations from 11 organisations working on in ? Well, it's now on YouTube! Don't be daunted by the 2 hour runtime - there are descriptive chapter markers so you can jump between presentations youtu.be/D5S4pUhjJbo
