I'm incredibly honored to be a part of this team and proud of this award!!! But I'm just a very small part of this program. Anita Marshall @bakingsodavolc.bsky.social deserves all the credit for the idea, the passion, the grunt work, and for its success!!! ⚒️🧪🔭

My latest for @earthscope.org, a dive into mapping sediment thickness across the US with Transportable Array data! ⚒️

No single map of sediment thickness across the conterminous U.S. existed that used a consistent method — until this new one based on Transportable Array seismic data.

For @temblorinc.bsky.social, @beccapox.bsky.social writes about interesting new developments in tsunami early warning using prompt elastogravity waves, a small-amplitude, fast-moving seismic wave. ⚒️🧪

Temblor, Inc. @temblorinc.bsky.social · 7d

Tsunami early warning systems offer important information about impending waves. New systems, like one that uses prompt elastogravity signals (or PEGS) can increase the timeliness and accuracy of warnings. For more, check out Temblor's latest, by @beccapox.bsky.social

This earthquake was originally reported as a magnitude 4.6 but was downgraded to a magnitude 4.3.

Remember, there is a trade off between speed and accuracy. As more data becomes available the initial reports are likely to be adjusted to reflect our improved understanding.

Feature not bug.

What went well, and what needs to be improved when it comes to major earthquakes that shake Istanbul? In @temblorinc.bsky.social 's latest, experts explore aspects of a recent M6.2 earthquake that shook the city and reportedly caused panic. 🧪⚒️

How does insurance work when it comes to events like tsunamis? This short Temblor article describes one way path, built on NOAA's tsunami monitoring efforts. 10 days after the Kamchatka tsunami hit Samoa, the country received a payout from PCRIC. ⚒️🧪

Just 10 days after the Kamchatka tsunami hit the shores of Samoa, the island nation received a payout from the Pacific Catastrophe Risk Insurance Company. Temblor played a role in this process.

Long but interesting! Check out @temblorinc.bsky.social's latest on the July 2025 Kamchatka earthquake, in which Temblor scientists look at stress transfer associated with 2 foreshocks. They also compare the mainshock to a similar 1952 quake, explore some tsunamis, and consider an eruption. ⚒️🧪

Temblor, Inc. @temblorinc.bsky.social · Sep 10

Temblor's analysis of the July 2025 magnitude 8.8 Kamchatka quake explores some mysteries (a moderate tsunami, a curious eruption), and finds that the 10-day foreshock was exceptionally productive.

Just downloaded! Going to love this when we go camping in a few weeks. Thanks for the rec! I'll use both the USGS site and RockD and report back my thoughts (if I remember to come back to this thread 🙃).

pC geology-only fail. Definitely... not what those boundaries look like between Idaho, Oregon and Nevada.

I'm glad to find that this is easy to do on the phone as well. I'm happily using two fingers to cruise around California at the moment!

So, to answer @callanbentley.bsky.social's question: in some ways, it could be so much better. But it's a pretty neat resource to have available to the general public. Anyone can pull this up on their phone and see what kinds of rocks they're in, how old they are, and what they're called.

Another gripe: I can't zoom in as much as I need! Maybe I'm just zoomed out too much to see, and it *is * actually correct! I can't tell!

Alka Tripathy-Lang @dralkatrip.bsky.social · Aug 29

For example, I zoomed into the region where I did my MS thesis, and it's... not quite right? It has different lithologies on either side of the road. Definitely not true, but you'd need to look at papers or go there to know this.

There is absolutely so much detail missing, especially at the outcrop scale.

I like the layer options; pC versus Pre-Q versus Q versus all. This was actually useful to me last night to fact check something I read, wherein I needed to see where all pC rocks were in the western US.

Prepare for a list!

I like that I can I can relatively easily see regional-scale geology. For me, this will be useful when we go to new places where I'm unfamiliar with the rocks. AND It's decent on my phone (I'm shocked by this).

Finally got a chance to process some of my backpacking photos from Late July. I hope to share some pretty photos and general geoscience descriptions of the area in the coming weeks. For now, here’s a sunset reflection on a small pond next to Lower Golden Trout Lake in the John Muir Wilderness.

A glowing orange mountain range is reflected into a small high Sierra pond at sunset. There are some granite rocks in the pond that are also reflecting, and the rims of the small pond are ported by larger granite, boulders and glacial, attics with grasses around the fringe of the pond and some Pine trees that are small interspersed.
