Heartbreaking to see these wonderful NCEI datasets being decommissioned: www.nesdis.noaa.gov/about/docume... I sent comments about the impacts of the loss of these data to ncei.info@noaa.gov and encourage anyone who uses NCEI data to do the same. 🧪

I’m thinking we should spread this news about the firings at NOAA as far and wide as possible. Like cancer research, weather forecasting seems likely to be broadly popular across the political spectrum. apnews.com/article/nati...

Allhands today discussing probie layoffs. The director of my lab just broke down after a question. He's not the only one. This is simply cruel.

I think it may because I was direct hire...? Almost everyone at my agency has a 3-year probationary period (but we do have a lot of direct hires). If they let all probies go, there will only be 3/10 of my team remaining.

I have not (yet?) been fired, but I am very concerned for my colleagues who are at risk (or already gone), and the future of my career and research at my agency and elsewhere regardless of what happens.

Thankfully, I finished my 3-year probationary employee at my current agency last October, but I've been a Federal employee and a government researcher for 9 years next month. Just some context as far as who they are firing right now. 🧪

It would be fantastic if major federal institutions would acknowledge that the executive branch cannot legally unilaterally cancel or redistribute congressionally appropriated funding on ideological grounds and thus they have no legal obligation to comply with such directives

We think it's probably related to the fact that they are not actually controlled by underlying structures, at least not recently - but we still have a lot of questions about how they formed initially!!

🧪🌊 New research on a field of pockmarks—large, circular depressions on the seafloor—offshore of Central California has revealed that powerful sediment flows, not methane gas eruptions, maintain these prehistoric formations. Learn more: www.mbari.org/news/new-res...

New 🧪 paper out on pockmarks offshore central CA! I collected/processed some of the cores used in the study, which was led by Eve Lundsten and MBARI @mbarinews.bsky.social. We found turbidites in the pockmarks suggesting they are maintained by sediment flows. More: www.mbari.org/news/new-res...

Ok, this is very fun. Clearly I've spent too much time with the Queen Charlotte fault 🤣 make your own research cloud based on Google Scholar here: scholargoggler.com 🧪
Word cloud showing words that appear most often in Dr. Walton's publication titles. Largest words are "fault", "Queen Charlotte", "Alaska", "California", and "offshore", other highlights include "earthquake", "seismic", and "landslide"

Dr. Maureen Walton @marinemaureen.bsky.social · 10/04/2024
Again, I am not an East Coast researcher, but hopefully I/we will learn more about the fault, geology, and potential triggers at the upcoming @seismosocam.bsky.social meeting in Anchorage! There is a special late-breaking session on the topic. (10/end) 🧪
010
Dr. Maureen Walton @marinemaureen.bsky.social · 10/04/2024
Regardless, these events are rare, and certainly scary since they are felt infrequently and the East Coast is not prepared for them. But again, they are rare and should remain so, because this is a passive plate boundary. (9/n) 🧪

Dr. Maureen Walton @marinemaureen.bsky.social · 10/04/2024
The NJ thrust fault may have slipped for a lot of reasons, again, none of them related to active plate tectonics. I don't know a ton about East Coast geology (hive mind - chime in!) but slip may have been triggered by gravity, isostatic rebound, rising sea level... Etc (8/n) 🧪
100
Dr. Maureen Walton @marinemaureen.bsky.social · 10/04/2024
Another key difference between NJ and a typical CA quake is the mechanism. The NJ event was a thrust fault, and CA events are typically strike-slip faults. But again, NJ was not related to plate boundary tectonics - it is NOT a subduction zone, whereas CA IS an active transform boundary. (7/n) 🧪
100
Dr. Maureen Walton @marinemaureen.bsky.social · 10/04/2024
This all means that a M4.8 earthquake in NJ could be felt very differently than a M4.8 in CA. Another factor, ofc, is how "ready" the population (and buildings!) is (are) for an earthquake this size. These are pretty standard in CA and people are used to/ready for them. Not the case in NJ. (6/n) 🧪
100
Dr. Maureen Walton @marinemaureen.bsky.social · 10/04/2024
The moment magnitude (here M4.8) is a calculation based on 1) amount of slip and 2) slip surface area. This magnitude calculation is thus unrelated to the shaking the earthquake produces (although of course, there is correlation - larger slip typically causes more/larger shaking). (5/n) 🧪
100
Dr. Maureen Walton @marinemaureen.bsky.social · 10/04/2024
Rock types also affect attenuation. Hard rocks (like bedrock in NJ) transmit energy faster than sediment, but do not amplify waves as much as sediment. Think of shaking a rice crispy treat vs a cube of Jello. Rock types and sediment cover absolutely affected how far/well this thing was felt (4/n) 🧪
100
Dr. Maureen Walton @marinemaureen.bsky.social · 10/04/2024
The depth of the earthquake (4.7km) is standard, on the shallow side for a crustal eq (0-15km). Shallow earthquakes will typically be felt more intensely than deeper earthquakes because shallow earthquakes undergo less high-frequency wave attenuation, so you feel more of the energy. (3/n) 🧪
120
Dr. Maureen Walton @marinemaureen.bsky.social · 10/04/2024
This earthquake happened as a result of slip on an ancient fault. This part of the continental margin is a passive plate boundary, and does not accommodate active plate tectonic motion. The fault that slipped probably does not separate two tectonic plates (most faults actually don't). (2/n) 🧪

Dr. Maureen Walton @marinemaureen.bsky.social · 10/04/2024
I thought I'd make my first science 🧪 post about about the recent NJ eq in light of some conversations I had about it afterward, and some not-quite-right takes I saw. My info is based partly on stats from the USGS page: earthquake.usgs.gov/earthquakes/... which is always a great spot to start. (1/n)
