Morning folks, time for my first Mastodon thread (!)

Ahead of the #midterms tomorrow, I want to talk about the tragic politicisation of science in the US.

It’s hard to pinpoint exactly when the Republicans became the anti-science party, but the process probably began in the 1980s, when the Christian right first emerged as a major force in conservative American politics.

Since then, the journey has been smooth and swift, and there is now a stunning partisan divide on confidence in science 😥

@JochenFromm indeed! #EarthquakeToot

it appears to be related to the Pesaro mare-Cornelia fault (using the Database of Individual Seismogenic Sources 3.2.0 in the google map).

this fault may be between 120-160km. using wells & coppersmith mag relations with subsurface rupt length, this fault could produce a mag M 7.7-7.7 #Earthquake

there were 2 events of similar mag in the past century. map below shows 1922-2022 M>5.5.

felt reports along the coast reached MMI 7

geoscope carte shows a thrust mechanism, probably on fault plane dipping to the west, unless this is on a fault antithetic to the mapped fault (so would be reverse dipping to the east)

#Photography has been a natural complement to the #fieldwork that I've performed over the years. It's afforded me opportunities to visit places like this canyon in northern #Iceland. The columnar basalt lining the canyon sidewalls are #geologist's dream!

This view was captured from my #drone during a trip in 2019. I had just finished performing fieldwork focused on #dronemapping several #periglacial and #glacial sites across the island and took the last week of the trip for some sightseeing!

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).

In #Canada, see the last hour of ground shaking here:

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

Just include your full mastodon link (like this: https://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!

The absolute BEST thing about Mastodon? No DMs… ☠️

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 (https://www.emsc-csem.org/Earthquake/earthquake.php?id=1187048#scientific)

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 😎

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