#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).

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)

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

generated 0.6-1.7m wave height
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

for M 6.9 in Taiwan on 18 September 2022

there was lots of damage and some casualties :-(

landslides and liquefaction models show that there was a high likelihood for these.

i am filling in some as I just got my website back up and running after almost two months of arduous work (steep learning curve getting web services set up on a robust server)

Greetings tooters!

this account is for Dr. Jason "Jay" R. Patton (aka EarthJay) and I march for science.

His main education/outreach effort is voluntarily writing up posts on earthjay.com. These are for and events of interest, sorted in different ways; sorted by year here: earthjay.com/?page_id=3220

they are an engineering geologist (PG license 9758) who serves the public while at the California Geological Survey, Seismic Hazards and Tsunami programs. conservation.ca.gov/cgs/

he has been studying the tectonics of the Cascadia subduction zone (a convergent plate boundary fault system) for over 25 years (MS thesis at cal poly humboldt, dept geology). he is an adjunct professor at this dept. geology.humboldt.edu/

they studied marine sedimentary records (submarine landslide deposits called turbidites) of earthquakes offshore of Sumatra/Cascadia for my marine geology & geophysics PhD at oregon state university. ceoas.oregonstate.edu/

capital letters are over rated but chocolate and oxford commas are not.

Ever seen a headline about #volcano smoke? The grey plume that rises from a volcano isn't smoke at all, it's volcanic ash (yeah I know, the confusing term doesn't help). It's made up of pulverized rock, crystals, glass, and gases, & produces different dangers to smoke.

It's also not at all fluffy like movies like to show.

You can learn more about it and how to protect yourself here: inthecompanyofvolcanoes.blogsp
