Happy holidays from your furiends at the zoo ✨ Thanks to Keeper Megan and Keeper Ali for the holiday pics!

This is hilarious. That last one hurt, though. I bet the multipath was very interesting. ⚒️🧪

An iceberg breaks off of Alaska's LeConte Glacier, one of the places glaciologist @exploreice.bsky.social has gone to for her research. A melting glacier's edge can be a dangerous place to visit and observe closely, so Pettit uses robots and sound samples to monitor melting ice. 🧊 #PictureOfTheWeek

🚨Extremely short notice: Looking for prospective PhD or postdoc w/ geological engineering or modelling experience, w/ interests in mountain geohazards for project focused on landslide-triggered tsunamis in subarctic w/ me & @geocron.bsky.social 🧵 🧪⚒️ Pls share! nserc-crsng.canada.ca/en/news/laun...

This is Millie. She just learned how to sled. Hopes you brought a second land frisbee, because she will not be taking turns. 13/10 (TT: millietheredlab)

I deeply relate to this new EarthScope sticker. I deal with brown bears instead of polar bears, but the behavior is the same. Intelligent, curious creatures who are sometimes complete jerks around GNSS stations. ⚒️🧪

On FB, Yukon Geological Survey posted some spectacular photos of landslides & snow avalanches triggered by the magnitude 7.0 earthquake on Dec 6 in the St Elias Mountains. Here are some of my favs. @geocron.bsky.social @theronfinley.bsky.social @davepetley.bsky.social @ksvenenvig.bsky.social 🧪⚒️

At #AGU25 and want to talk about #geodesy education and growing the geodesy workforce? Come check out this poster session this afternoon. I'll be there with a poster (G13B-0268) on MSU's undergraduate summer geodesy internship program. ⚒️🧪

Our friends at USGS landslide group have some preliminary results about landslides and rock/ice avalanche that occurred from the M7.0 Hubbard Glacier earthquake on Dec. 6. I remember some people asking about landslides caused by this earthquake. Here you go: www.usgs.gov/programs/lan.... 🪨⚒️🧪

Hi US science folks, NSF has released some policy changes to the document I know you’ve memorized: the PAPPG. Take a look, send me your questions, I’ll add them to our own and try to get some answers. www.nsf.gov/policies/doc...

Make the mountains shake! 🏔️🔥 Each new whitish area on today's Sentinel image below is a landslide triggered by the Hubbard Glacier M7 earthquake (Alaska) on Dec. 6th! 😲 Mostly ice, but also rockslides! 🧊🌊

OMG it just took out one of the distant cameras!!

🌟OPEN ACCESS🌟In a new #BSSA paper, scientists compare a 1912 Denali earthquake with a more recent 2002 magnitude 7.9 event in the region. ⚒️ pubs.geoscienceworld.org/ssa/bssa/art...

Today I’m joining the #GivingTuesday challenge to save the Museum of the Earth. As a Board of Trustee emeritus member, I see first-hand the Museum's impact on educating our community and the world about climate change, biodiversity, and our home planet. Please donate at priweb.org/support.

Monitoring crustal deformation: sometimes in the lithosphere, sometimes on your pie plate. 🍁🍂 Happy Thanksgiving from EarthScope!

Oof, I feel this one, I’ve seen this more than a dozen times, it was the first glacier I stood on. www.ktoo.org/2025/11/25/m...

One secret to buildings that won't collapse during earthquake shaking is shear strength, as this simple model can demonstrate. Check out these related classroom resources for more: https://loom.ly/mAqr054

Cool study that uses acoustic signals recorded at seismic sensors to identify aircraft type flying overhead (different aircraft have different frequency signatures). Alaska provides a lot of aircraft variety to evaluate. ⚒️🧪🚁 pubs.geoscienceworld.org/ssa/tsr/arti...

I am hiring 4 postdoctoral researchers for up to 4 years each. Topics include ice sheet reconstruction, GIA, spatial stats, and satellite geodesy. Based in Tasmania. All details are here: careers.utas.edu.au/en/listing/ with titles below I am also recruiting multiple PhD students (see below) 1/n

Part 2 of our history of the remarkable flight of the California Clipper in WW2 is now available. To get back to the US after Pearl Harbor, Ford and his crew are asked by Pan Am to do something no commercial aircrew or passenger plane has done before: Circumnavigate the world. #history #aviation

It's #WorldTsunamiAwarenessDay. Before warning systems existed, tsunamis could be a surprise. A 1946 M8.6 earthquake in Alaska launched a tsunami that devastated Hilo, HI and killed >150 in the HI Islands. Now warning infrastructure in AK is being defunded, weakening the network. ⚒️🧪🌊 bit.ly/4oqexnR

#30DayMapChallenge Day 4: My Data Hardware stores I have visited/spent too much money in while doing fieldwork in southern and interior Alaska. Maybe one day I'll make it through a trip without needing to stop at a hardware store (but probably not).

#30DayMapChallenge Day 2: Lines Think your commute is rough? Here are migration paths of Arctic terns that breed in Alaska. Each color represents the round trip track for an individual tagged bird. Migration data source in comment. Map made with the Generic Mapping Tools (GMT).

Today is International GNSS Day. October 23 was chosen because 10.23 MHz is the foundational frequency for GPS. The world has become dependent on GNSS, but there are threats to service continuity. It is good to take a day to appreciate the value of GNSS. #geodesy www.ion.org/news/interna...

CLaSH is seeking an Assistant Director to help lead an ambitious, interdisciplinary effort to transform the science of and advance community resilience for hazards like landslides and flooding. Apply by November 15th. See also csdms.colorado.edu/wiki/Jobs

Ever seen a 750-pound muskox face off with a 210-pound pumpkin? 💥 Hudson did, and won! 🏆 Catch more pumpkin-smashing, leaf-crunching, fall fun during #ZooBoo, October 18 & 19. 🎃🐾

When you see photos of GPS stations, you’re usually looking at the protective radome cover and not the GPS antenna itself. The gray radome helps shield the antenna from rain, snow, and debris buildup and protects it against general wear.

They have dogs coming in from Kwigillingok (aka "Kwig") as well and this is how some are getting tagged. Lots of Typhoon Dogs getting rescued from the YK-Delta, and the folks doing it could use your help. Donate here: www.bethelfriendsofcanines.com/donate.html

This is the Western Alaska animal nonprofit working to rescue the pets in Kipnuk. The residents of Kipnuk are under a mandatory evac order but can not bring their pets with them. Supporting this group will help with charter aircraft, etc. www.bethelfriendsofcanines.com

‘Miserable’: Hundreds sheltering in Western Alaska schools in dire conditions "In Kwigillingok, some 400 people were sheltering at the school, without functioning toilets ... in Kipnuk, where the water plant wasn’t working and electricity was limited." www.ktoo.org/2025/10/15/m...

Western Alaska was hit hard by the recent storms. Houses floated away in Kipnuk, houses flipped over, people lost everything from the flooding that came with the storms. Please donate if you can. This group has a long history of supporting AK communities. alaskacf.fcsuite.com/erp/donate/c...

At least 20 people are unaccounted for in Kwigillingok, in the Y-K Delta as of Sunday morning, and several homes were flooded and carried away by the remnants of Typhoon Halong - the worst storm on record.

It’s happening again in November. 30 days and 30 themes for maps. Take part, learn something new and have fun. That’s what #30DayMapChallenge is about 🌎

For #FieldworkFriday, some of the benchmarks I've surveyed over the past few weeks. Some are more challenging to use than others, but they're all interesting. #geodesy ⚒️🧪

New Paper! We investigate the first several months of postseismic motion following the M8.2 2021 Chignik earthquake on the Alaska subduction zone and how that motion can help improve our understanding of coseismc slip. ⚒️🧪 agupubs.onlinelibrary.wiley.com/doi/10.1029/...

EarthScope is excited to be undertaking operations of the NSF National Geophysical Facility, as of October 1. Curious what this means in terms of geophysical research and education support? Check out these helpful FAQs. ⬇️ https://ngf.earthscope.org/

A campaign GNSS site in Willow, Alaska, set up to tie previous time series with the new EarthScope/NOTA continuous GNSS site nearby (the old NOTA site got whacked by a snow plow). The white crags in the center background are Mt. Foraker (left), Mt. Hunter (middle right), and Denali (far right). ⚒️🧪

Engaged in a bit of gardening this morning. In related news, I'm pretty sure I know why data from this GNSS site has been showing high levels of noise. Also, I hate cottonwood, alder, and their ilk. ⚒️🧪
