Huge active fault plane at Genoa ridge, perfectly E-dipping! #normalfaults #sierranevada

Quickly plot the rough location of the 2025 Mw8.8 Kamchatka earthquake (USGS hypocenter) on Figure 1 in Pinegina et al. (2018). I wonder if the 2025 event re-rupture the northern rupture of the 1952 Mw9.0 event? Also, did the 2025 event rupture across the "segment boundary" at ~N53? rdcu.be/eyrre

@seislologist.bsky.social looks like you might need to update the shirt after todays event!!!!

A beast of a soil. Mt Rose Nevada

USGS research has uncovered a 700-year sequence of major earthquakes in the eastern Aleutian Islands through tsunami evidence and modeling. This work enhances our understanding of seismic hazards in the region. 🌋⚒️🧪 #Seismology #TsunamiResearch #AleutianIslands #EarthquakePreparedness

Cascadia subduction zone earthquake could be even worse than feared. A once-every-500-years earthquake in the Pacific Northwest could shake for 5 minutes and cause 100-foot tsunami waves. That would be just the start of the horrors. ⏬ Bluesky bite-sized article thread (7 min) with added links 📖🍿🔊

“We’d be losing the cornerstone report to communicate to the public the risks we face with climate change and how we can move forward,” said Dustin Mulvaney, professor of environmental studies @SJSU, an author on the southwest regional chapter. www.nytimes.com/2025/04/28/c...

Bummed on the overall lack of surface rupture pics from the recent earthquake in my feeds!!!!

Our hearts are with Myanmar today. Also filled with tremendous sorrow and shame for our country that USAID isn't there to help.

At least I have 6 Nations Rugby to watch.

Plese share

Fog over Truckee all the way up to Donner Summit

Magical INSAR led us to rupture from the M5.8 Parker Butte Nevada earthquake. 1.5 km of surface rupture, right lateral, max offsets 2-5 cm, on NNW plane. Conjugate to NE trending aftershocks.

Quick recap from todays recon of yesterdays M5.8 earthquake. Bottom line: no surface rupture observed after several transects across aftershock pattern.  Lack of any surface cracking in epicentral area. Minor bank failures, lateral spread, and liquefaction features along Walker river.

Good little shaker felt at the office

Nice to see all the posts on the CA earthquakes here today. However, still need more agencies and individuals to migrate on over. Prob best for agencies to post on multiple platforms for greatest reach.

Happy T day. Powder turns for the win.

Hi, my name is Jack. Im pretty smart when it comes to sticks and squirrels.

Enjoying seeing all the old tweeps and friends on here. Starting to feel like the old days as this account picks up steam. Ill post about adventures, dogs, faults and dirt, and a little weather.

The science is great over here. Heres the Genoa fault for a Friday pic.

It would be nice to see zero politics in this place. Isn't that why everyone bailed from the other place in the first place.

Come join our geoscience group at University of Nevada Reno! We have a new faculty opening for the Director of the Great Basin Center for Geothermal Energy. More details below. UNR is an awesome place to live and work! nshe.wd1.myworkdayjobs.com/UNR-external...

Earth Science Week field trip teaching general public about ash flow tuffs.

Nevada doing Nevada things.

What a day.

Field geo class in front of the storm. Great attitudes all around!

Storm window opening in a big way in the Sierras

Little Walker Lane shaker close to home!

Productive meeting with state geology partners reviewing hazard programs

Sometimes the geology has to wait.

Livin it up!

Slow start to winter, but still a nice day on the hill.

Looking south along Mission Creek strand of the San Andreas fault. Friends of the Pleistocene!!!!

About an hour after the Loma Prieta earthquake 10/17/89 Santa Cruz harbor.

Nice progressively offset alluvial surfaces and faceted range front, central Nevada

Donner Peak!

Seasons a turnin

Just in to keep my eye on you earthquake people
