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. ⚒️🧪

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. ⚒️🧪

🔥PRESS RELEASE🔥Revisiting an Enigma on California’s North Coast: The Mw 6.5 Fickle Hill Earthquake of 21 December 1954 #BSSA What lies beneath Fickle Hill? The answer may help solve an earthquake mystery that has puzzled seismologists for decades. PAPER: pubs.geoscienceworld.org/ssa/bssa/art...

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.

During a tsunami warning we always caution that a tsunami arrives as a series of waves and the first arrival is not always the largest. Larger tsunami arrivals can occur hours later. We can see this from the recent M 8.8 Kamchatka earthquake.🧪

I'll be on sabbatical starting January 1, 2026, and if anyone is looking for a guest speaker for department seminars, I'm happy to discuss possible dates. Reskeet widely! 🧪⚒️

Since people are still doing it and I'm going to have time to kill until I figure out what to for the rest of a chaotic week that promises to have lots of little pockets of down time: 1 like = 1 opinion about subducting slabs.

I am glad @evanbush.bsky.social used this quote in this excellent @nbcnews.com story. This is a key message I really wanted to get across in interviews today. Article here: www.nbcnews.com/science/scie...

the California Geological Survey has prepared a survey to gather your observations from the M8.8 Kamchatka, Russia Tsunami If you have been able to make any observations of the tsunami or of the evidence left behind by tsunami, we want your information: survey123.arcgis.com/share/76979d...

Great article with comments by @diegosismologo.bsky.social, @acarrerac.bsky.social, @seismo-steve.bsky.social and @judithgeology.bsky.social. Though the tsunamis weren't as massive as past events, people evacuated because of timely warnings and accurate forecasting of when/where waves would arrive.

Look at that hydrograph! This is from a USGS monitoring well in Christiansburg, Montgomery County, VA. Observation well 27F2 SOW 019 is 450' deep, completed in carbonate rocks of the Elbrook Formation and well known for its response to quakes. ⚒️🧪 Data: waterdata.usgs.gov/monitoring-l...

Per Tsunami.gov, the largest tsunami heights were: 5.7ft at Kahului, Maui 4.9ft at Hilo, HI 4.0’ at HALEIWA HI 3.7’ at Crescent City, CA. Complete list and wave periods are linked: www.tsunami.gov/events/PHEB/...

Temblor's map of the magnitude 8.8 Kamchatka earthquake has been posted. Wishing everyone in the Pacific coastal region a safe night on high ground as the tsunami waves come in. ⚒️🧪

The Earthquake Insights article about the Mw8.8 Kamchatka earthquake is, as always, really informative. ⚒️🧪 #geology open.substack.com/pub/earthqua...

Watch the seismic waves from the magnitude 8.8 earthquake off the coast of Russia sweep beneath seismic stations in North America. By the time the waves reached North America, they are far too small to be felt by people, but can still be detected by seismic instruments. 🧪

⚒️ 🧪 A M8.8 earthquake just ruptured the subduction zone offshore Russia’s Kamchatka peninsula. This is one of the world’s truly huge earthquakes, and a triggered tsunami is currently traveling across the Pacific ocean. This same fault ruptured on July 20th in a M7.4, and last August in a M7.1.

The magnitude 8.8 earthquake off Russia’s Kamchatka Peninsula is tied for the 6th largest ever recorded by modern instruments. Check out how the ground moved near you using our Station Monitor app ⬇️ https://loom.ly/LvUPs2g

Today's M8.8 (orange circle) and the 1952 M9.0 epicentral locations, separated by only 73 years. I wouldn't have thought that possible! Average recurrence intervals don't tell the full story. ⚒️

What governs whether the next big Cascadia earthquake will rupture the entire margin or stop partway? In our @weareseismica.bsky.social paper led by Jonatan Glehman, with Thomas Ulrich, Marlon Ramos, Yihe Huang, & Eric Lindsey, we link geodetic slip deficit models to 3D dynamic rupture simulations..

🔥JULY ISSUE OF #SRL🔥 In the latest issue, dozens of articles span topics ranging from earthquake source parameters to an exploration of "Did You Feel It" reports. Also included are articles in the Electronic Seismologist section and Data Mine section. ⚒️ pubs.geoscienceworld.org/srl/issue/96/4

Well worth clicking through to Read the letter. A very good, clear & concise description of the tangible benefits that are at risk. Every science program being gutted should follow this model. 🧪⚒️🌋🫨

⚒️ calling all geoscientists! It is vital we make our voices heard. These programs (like so many others) are vital to keeping thousands of people safe from natural hazards!!

This loop of the surface rupture is absolutely mesmerizing. I’ve spent the entire week so far watching the whole video repeatedly, and each time I discover something new. ⚒️ 🧪

📖 NEW #SRL ISSUE📖 The cover shows a turquoise lake in the Huaytapallana mountain range of the Peruvian Andes. A paper by Tavera et al. discusses the collection of seismic data from a temporary network in this region. What a field site! ⚒️ pubs.geoscienceworld.org/srl/issue/96/3

New paper out by my team, led originally by the late Jasper Konter, an amazing human being and scientist, and with important contributions from the late Paul Wessel, both of whom we lost during review. The whole team stepped up to get this paper to the finish line. www.nature.com/articles/s41...

For @earthscope.org, I talked to @seismosue.bsky.social about her recent earthquake ghost story (published in @seismosocam.bsky.social's #SRL) and graduate student Oluwaseyifunmi Adeboboye, who helmed separate work looking at a curious, possibly comparable swarm elsewhere in South Carolina. ⚒️🧪

It's been 10 years since the 2015 Gorkha, Nepal earthquake that killed and injured thousands. @seismosue.bsky.social and her NSET colleague, Surya Narayan Shrestha, reflect on what happened, the recent seismic history of the region, and what's been learned. ⚒️🧪

Need some tips to prep for West Coast quakes? This piece by @debi-kilb.bsky.social, @inseismoland.bsky.social, John Rekoske and Duncan Agnew has some advice, as well as a great discussion of the April 14 M5.2 Julian earthquake. ⚒️🧪
