Last day for submission!

Our latest nature paper shows the power of DAS. Using a 100km cable, we imaged four asperities breaking during a M6 event, whose image would otherwise be a blur. It is like having a new telescope, but for earthquakes! What if we have all the cables?! rdcu.be/dioaw

Why was the earthquake so large? In our recent paper in Science Magazine, we revealed how the destructive Turkey earthquakes this year gradually ruptured and evolved in a multi-fault web, forming a domino-like cascading effect! Link: doi.org/10.1126/scienc…

Another highlight is the integration of near-field and far-field seismic and geodetic data-based modeling, as well as independent physics-based simulation, leading to truly unified understandings! Hope this becomes a new standard in future major earthquake responses.

Our new paper Science Magazine combines diverse data sets & earthquake analysis, from geodesy to 3D rupture dynamics, teleseismics to near-fault ground motion, to unravel & explain the complex #TurkeyEarthquake earthquake doublet. Led by Zhe Jia IGPP at SIO science.org/doi/full/10.11…

Really nice story by Alex Fox that covers our study on the #TurkeyEarthquake : Unexpected Physics Behind Turkey’s Devastating 2023 Earthquakes. scripps.ucsd.edu/news/unexpecte…

Interested in T-wave and ocean bottom DAS? We systematically studied the performance of DAS for T-wave detection and ocean seismic thermometry. After curvelet denoising, OBDAS does a slightly better job than nearby OBSs. Here is the preprint: essopenarchive.org/doi/full/10.22…

Our paper on the metasomatic origins of the mid-lithosphere discontinuities just got published on the open-access journal AGU Advances! dx.doi.org/10.1029/2023AV…

Phase picking in DAS is challenging with noisy data and thousands of channels involved. Our new paper in Nature Communications demonstrates how #MachineLearning effectively handles this. Explore PhaseNet-DAS! @zhuwq0 Jiaxuan Li Jiuxun Yin Zachary Ross nature.com/articles/s4146…

A M7.5 earthquake struck western Japan today, collapsing buildings & triggering a tsunami. Most large earthquakes occur with no warning, but this fault has been noisy for over 3 years: an evolving swarms and a M6.2 in May. And now a M7.5! Read more on our blog - link in my bio.

Rupture process of the 2024 Jan 1st Magnitude 7.5 Japan earthquake revealed from a preliminary subevent model derived with teleseismic waves. First ruptured to Southwest then bilaterally ruptured to Northeast. Should be refined when better hypocenter and local data available.

Thanks, Zhongwen!

New study alert! The 6 subevents of the 2024 Mw 7.5 Noto Peninsula earthquake show complex rupture pattern—a slow start, an onshore westward break, then an offshore rupture 20s later that fueled the tsunami! Potential for better tsunami warnings🌊 more: doi.org/10.1029/2024GL…

Nearly-automatic rupture model for the 2024-12-05 Mw 7.0 offshore Mendocino quake (CA): simple mechanism, good waveform fits. E1-E2 depths ~3 km. Appears promising for rapid response & hazard assessment.

For the first time I‘m attending #AGU24 AGU (American Geophysical Union) and I am excited to share our recent work on the Noto Peninsula #earthquake. Find out how source complexity governs #tsunami generation in my talk NH51B-06 agu.confex.com/agu/agu24/meet…

The 2025 Jan 7th M7 Tibetan quake, analyzed using teleseismic data, ruptured northward slightly east at a relatively slow ~2.5 km/s. Three subevents, 2nd most energetic, deepen from ~5 to ~9 km: a likely ~50° east-dipping fault plane. Hoping for more rescues from this tragedy.

#MyanmarEarthquake may be a long supershear event (~5 km/s, ~350 km rupture), evidenced by S wave arrivals on the strong motion data, which explains strong shaking felt far away. Supershear amplifies damage, calls for urgent rescue needs & infrastructure strengthening.

How do earthquakes happen >500km deep, where rock should flow, not break? Our new study doi.org/10.1029/2025AV… provides a dual mechanism explanation: metastable olivine transformation causes initial break, then the rupture melts rock and fuels a runaway to release massive energy
