In a new #BSSA paper, scientists consider why Alaska seismic station NP.ARTY experiences higher ground acceleration than other nearby stations. They found that local topography and shallow low-velocity material play important roles in amplification. ⚒️ pubs.geoscienceworld.org/ssa/bssa/art...

🌟OPEN ACCESS🌟 Although Australia isn’t known for high seismicity, it does experience moderate to large earthquakes. A new #BSSA paper presents a way to resolve source parameters for well-recorded post-1994 earthquakes within Australia. ⚒️ pubs.geoscienceworld.org/ssa/bssa/art...

How might a sudden change in slab dip affect rupture propagation? A new #SRL paper proposes that in the case of megathrusts that occur south of the Alaska Peninsula, such as change may have acted as a barrier for two recent quakes. ⚒️ pubs.geoscienceworld.org/ssa/srl/arti...

Another quick comparison of the 1952 #Kamchatka #earthquake from MacInnes et al. (2010) with today’s M8.8 event. The aftershock areas are similar, as well as one region of foreshocks. The updated USGS rupture model has a max slip of 10m versus 12m for 1952, with SW rupture direction. 🧪⚒️

“The village’s 300 inhabitants had to leave their homes on 19 May after geologists monitoring the area warned that the glacier appeared unstable. Now many of them may never be able to return. Climate change is causing the glaciers – frozen rivers of ice – to melt faster and faster..”

⚒️ 🧪 Two weeks ago, a video appeared showing slip in the Myanmar earthquake - the first time this has ever been recorded on video. What can we learn from it? We deep-dive the science. earthquakeinsights.substack.com/p/remarkable...

Pretty convinced that our work at Saint Louis University on the Cauca Cluster earthquakes has developed to the point we can probably make a fairly decisive argument on the cause or causes of the intermediate depth earthquakes.... Maybe we pitch it at AGU this December, if US science still exists?

There's a great paper by Dave Hill (former USGS seismologist) about the Mammoth crisis at link.springer.com/chapter/10.1...) He spent much of his career running the Long Valley Observatory (now CalVO) and working to repair trust in the USGS in Mammoth.

DAS meets the Moho! New paper in Science Advances w/ Zhongwen Zhan. We developed a method for finding Moho reflections in DAS data. One event can yield 10s of km of fine-scale Moho depth measurements. We applied it to dozens of SoCal events and learned a lot about the Garlock, Coso, and more.

Hi Seismo-Bluesky! I decided to test a pipeline with SeisBench, PyOcto, NonLinLoc, and HypoDD on the Santorini sequence. The level of activity (>4,500 events) is truly stunning! There are repeated bursts migrating backwards and forwards, spreading outwards from a narrow, almost linear channel.

The most iconic figure in the environmental sciences is the Keeling Curve, the CO₂ record from Mauna Loa, Hawaii. @noaa.gov had a wonderful site where you could visualize and download these data, and now it's just gone. These data belong to us and we should not let this happen!

Come ON. You fight unconstitutional moves even if the target is unpopular because the next target will be for something even bigger and more important. And because many innocent people will die.

🚨New paper! The second paper from @myfaultmanu.bsky.social's PhD thesis investigates the active tectonic deformation across the Western Anatolian Extensional Province in Türkiye using Sentinel-1 derived InSAR velocities.⚒️🧪🪨🛰️ OA paper here: agupubs.onlinelibrary.wiley.com/doi/10.1029/...

(For my part, I processed InSAR data over Dickson Fjord and was able to independently detect decorrelation consistent with the expected tsunami run-up around the edges of the fjord. I did not find any obvious pre-event signal on the rocky peak, but it certainly did decorrelate after it fell.)

I am so excited for everyone to see this amazing story about the mysterious seismic signal, mega-tsunami, giant rockslide, and perpetual wave machine of a fjord! www.theguardian.com/environment/...

The M3.9 near Ontario at 10:34am was preceded by a M3.5 about 30min before. Both confirmed valid. The area has had 13 events in the past 3 days and 8 aftershocks as of 10:59am.

“Seismic waves from earthquakes produce strong enough electric voltages in quartz to extract dissolved gold from fluids infiltrating the mineral. This mechanism can help explain the creation of large nuggets and observed highly interconnected gold networks within quartz vein fractures.” 🧪⚒️

Whenever someone asks me for a cool #mineral fact or why quartz is my favourite, I always mention its piezoelectricity (it generates an electric current when squeezed) It turns out this property is why gold nuggets are common in quartz 🧪⚒️ #geology #science www.nationalgeographic.com/science/arti...

Supercool! And now I’m wondering about what this means for the Witwatersrand gold deposits (formed around 3 billion years ago) and the eternal debate about when plate tectonics started)…

This is actually the velocities for Wadsleyite, the transitional mineral between Olivine and Ringwoodite. Ringwoodite is shown in a near identical figure in yet another Zhou et al. paper: Basic fact still applies--garnet is much slower than the other abundant mantle transition zone minerals.

66 million years ago, a huge object from space slammed into Earth and gave the dinsoaurs a really, really bad day. ... and now we know what it was: an asteroid, not a comet, and it came from the outer solar system. badastronomy.beehiiv.com/p/dinosaur-k... 🔭🧪

So much discovery came from the Joides Resolution. Hopefully NSF will find a way to revitalize the vital window into earth’s past that deep-sea drilling provides (gift link): www.nytimes.com/2024/08/26/s...

🧪 ⚒️ A M4.9 earthquake shook west Texas last night - yet another event likely associated with oil & gas extraction. The swarm that produced this quake started in 2020, and is probably linked to wastewater injection or hydraulic fracturing. Read more on our blog:

Increased earthquake activity near Pauahi Crater & ground deformation at Kīlauea’s upper East Rift Zone began July 23, indicating the likely movement of magma in the subsurface. The activity may remain below ground but an eruption is one potential outcome. ⚒️🧪🌋 www.usgs.gov/observatorie...

If we don’t fully understand how the ocean works, we can’t protect it (or ourselves). That’s why scientists like Cassie Bongiovanni, Kathy Sullivan, Nicole Yamase, & Sylvia Earle have dedicated their lives to mapping the deep. It’s what motivates me. 😍 www.esri.com/about/newsro... 🧪🦑

That's definitely over 100 ft. Probably over 200 ft. Incredible. Terrifying. Awful. I think people got lucky today because I saw sinter blocks sitting in holes like this, having completely punched through the boardwalk. (NPS photo) ⚒️ 13/

🧪There's a large scale exercise happening this week in St Louis to simulate what would happen in the event of a large earthquake in the New Madrid Seismic Zone. Sounds like a good oppertunity to read about the science of this weird earthquake zone in my latest for Undark. undark.org/2024/07/15/e...

Icelandic Met Office: “There is a very high probability of a new eruption or magma flow on Svartsengi in the next three week. In the new risk assessment for the area published yesterday, it is stated that there is an increased chance of lava emerging within Grindavík.” www.ruv.is/english/2024... ⚒️🧪

Couldn’t agree more! That’s why supporting non-profit journals is really important. Shameless plug: please consider sending your geoscience papers here: www.geochemicalperspectivesletters.org

Elsevier,Wiley,Taylor&Francis,Springer Nature&SAGE revenues are in billions. Academics do almost all work: research, writing, refereeing & editing journals. Publishers don't pay us for work; they then sell journal access to the universities that fund the research & editorial labor @ exorbitant cost🧪

First large earthquake in a while: M7.2 near the coast of Peru. Based on depth and focal mechanism from GEOSCOPE, this is likely a shallow subduction thrust earthquake with potential to generate a (likely small) tsunami 🧪⚒️

🧪 ⚒️ A M7.2 earthquake struck southern Peru last night, causing minor damage. The quake was preceded by foreshock activity since June 16. History tells us that many much larger, more damaging earthquakes have occurred here - and will again. Read more on our blog:
