New paper out on blueschist deformation experiments!!! 🚨🚨🚨 From the exps we developed a flow law and some of the first rheological constraints on diffusional properties in amphibole. @sgt_ethz . Check it out #OpenAccess #microboudinage

🚨 WE HAVE TOUCHDOWN!!! 🏁

40 days, 3 hrs & 29 mins after launch, CHANDRAYAAN-3 has successfully touched down on the Lunar surface!! 🌖

MASSIVE congrats to @isro & the global spaceflight community!

The south polar region of the Moon is no longer empty! 🛰️

Today's Mw 5.1 earthquake in Ventura County may be related to the Lion Canyon and San Cayetano faults. https://t.co/hJ2WxBUiPE Looking forward to more details.

[Sylvain Barbot @quakephysics]

Research software developers, you may appreciate the recommendations from @UCDgeodynamics on how to build community codes. @YouTube playlist https://t.co/FwEE6WUlGn A follow-up, in-person workshop with be held in Palm Spring during the SCEC annual meeting.

[Keenan Crane @keenanisalive]

Excited to announce our #SIGGRAPH2023 paper

"Winding Numbers on Discrete Surfaces,"

with @nicolefeng_ and @MarkGillespie64.

In essence, we address the question: given a jumble of curves on a surface (possibly noisy & broken), which points are "inside" vs. "outside"? [1/n]

[Communications Earth & Environment @CommsEarth]

Opportunity @CommsEarth: we are looking for a talented full time editor to join our team, closing date 11 Aug. https://t.co/pWw0gaGqzp

Earthquake prediction is physically possible (just not technically achievable with present sensors): https://t.co/ftTrlHdOcH

A touching article about An Yin by Mark Harrison https://t.co/QqHGt7p6Dw

[Quentin Bletery @BleteryQ]

We stacked all the GPS time series ever recorded before large earthquakes. The result is pretty interesting: https://t.co/nw06zqoOkG

Saddened by the unexpected loss of UCLA Professor An Yin, a dedicated teacher & renowned geologist. Our thoughts are with his family. Rest in peace, Professor Yin. 🙏 #RIP #InMemoriam @UCLAEPSS

[Yann Klinger @KlingerYann]

In our new EPSL paper, using trenching, coring, and CPT data we explore how changes in the Salton sea level impact seismicity along the Imperial Fault, South California.

Job advert now live! We're looking for a new postdoc to join the @MAST_ERC team. @UoBEarthScience @NERC_COMET @UoBGeophysics @UoBristolVolc . Advert here: https://t.co/WYh5EwLBCK. Flexible start date. Contact me if interested.

[Sylvain Barbot @quakephysics]

The talk from Paul Selvadurai is available online. https://t.co/MN9yA4Zlnb A main takeaway from the presentation is the use of Distributed Fiber-Optic Strain Sensing (DSS) in laboratory experiments to study confined ruptures. Very informative session.

[Sylvain Barbot @quakephysics]

Dr. Paul Sevaldurai, ETH will discuss complex deformation and localization of brittle failure in triaxial tests on crystalline rocks. Join us this Friday, May 12, at 1 pm PST. @UCDgeodynamics
More information and registration at https://t.co/cVG1V95fBg

[Sylvain Barbot @quakephysics]

Recent work from Paul includes studying precursory phenomena in the laboratory and modeling seismic cycles using a modified rate- and state-dependent friction law. https://t.co/s6XfjgjjRk

[Sylvain Barbot @quakephysics]

The talk from @c____sy is available online https://t.co/P09za8jEzQ. She discusses healing and failure in clay-bearing fault gouges with relevance to shallow subduction zones.

[Sylvain Barbot @quakephysics]

On Friday, May 19, 1-2 pm PST, Dr. Caroline Seyler @c____sy will discuss healing and failure in clay-bearing fault gouges. Dr. Seyler is an NSF postdoctoral fellow at Univ. Minnesota and will be joining the faculty
@USC_earth next year. Registration at https://t.co/U2QZBXV6Vy

[Sylvain Barbot @quakephysics]

.@c____sy is interested in the field, microstructural, and experimental studies of rocks, spanning the brittle and ductile fields. See a recent publication on the fracture energy of incoming sediments at the Cascadia subduction zone https://t.co/EURTMFUm07

[Sylvain Barbot @quakephysics]

The talk from Dr. Matěj Peč is now available at https://t.co/guMDFpyeuD Enjoy the great science.

[Sylvain Barbot @quakephysics]

This Friday May 26 at 1-2 pm PST, @UCDgeodynamics will host a webinar by Matej Pec, MIT "What does a Brittle-to-Ductile Transition Sound Like?" Registration at https://t.co/JNvqtCCM6u

[Sylvain Barbot @quakephysics]

A personal favorite is the study of the brittle-ductile transition on granitoid rocks showing a change of stress power exponent from 140 to 10 accompanying changes in activation energies from 80 to 180 kJ/mol.

[Sylvain Barbot @quakephysics]

Another important analysis is the activation of creep on pseudotachylites, which is formed by rapid quenching of bulk melting in the fault zones. https://t.co/xKSFfc4VOt Don't miss this occasion to hear from Dr. Violay.

[Sylvain Barbot @quakephysics]

Dr. Marie Violay will finally give her talk: "Mechanical behavior of lubricated faults during earthquake nucleation and propagation" on Friday, June 9 at 1-2 pm PST. Registration at https://t.co/oEegVgYGAR Join us for the talk and Q&A. This is the last seminar in the series.

[Sylvain Barbot @quakephysics]

Another work of great relevance to earthquake cycles is the determination of physical parameters for dynamic weakening during earthquakes. This is key to representing all phases of earthquake dynamics, including propagation at high slip speed. https://t.co/c79dVrA7hp
