Anthony Lomax 🌍 🇪🇺🇺🇦

The seminar program continues! Highlights from the seminar by dr. Anthony Lomax, held in celebration of the 25th anniversary of #INGV #Catania #Geophysics #Seismology #RealTimeResearch #SeismicAnalysis 📸 Ornella Cocina, INGV

Note that the shallow, blue cloud in the movie is not seismicity, but instead a very rough attempt to image a volcanic intrusion during the 2018 Etna flank eruption using the "seismicity-stress" procedure: arxiv.org/abs/2404.05437

In September of last year, Earth rang like a bell for nine days, baffling scientists. Now they’ve finally discovered the source: a mega tsunami in a remote Greenland fjord triggered by a colossal rockslide! My latest @ScienceMagazine science.org/content/articl…

Out today! Results of a multidisciplinary collaboration of dozens of scientists across the globe (including me)! A rockfall into a glacier into a fjord in Greenland caused a tsunami and seiche that generated a monotonic seismic signal for 9(!) days! bbc.com/news/articles/…

Watching our journal's article views climb shows how our community can make a difference through true open access visibility. Thank you to all the authors, readers, volunteers, and our host @McGillLib for being an integral part in this journey

Celebrating two wonderful years since our launch! Many articles and issues later, we are even more committed to making a difference and to continue improving this Diamond Open Access Journal for all. Explore all our issues here: seismica.library.mcgill.ca/issue/archive

Our latest research on High-Precision Earthquake Locations Delineating Active Fault Zones at Campi Flegrei Caldera has just been published with @theAGU in Geophysical Research Letters. Read here: agupubs.onlinelibrary.wiley.com/doi/10.1029/20…

Updated preprint: Mapping finite-fault slip in 3D from spatial correlation between seismicity and point-source Coulomb stress change [updated synthetic fault slip analysis, minor text changes] Preprint: arxiv.org/abs/2404.05437 Poster: zenodo.org/doi/10.5281/ze…

Il riconoscimento delle fasi sismiche attraverso algoritmi di deep learning può trarre vantaggio da un precondizionamento del dato basato sull’esperienza dei sismologi. seismica.library.mcgill.ca/article/view/1…

Seismic phase recognition with deep learning algorithms can benefit from transforming the input seismograms based on the experience of seismologists. Read more: seismica.library.mcgill.ca/article/view/1…

Check out my first 1st-author paper from my PhD work to learn about transpressional fault bends in the Mojave Desert of California! So thankful to get this work out and for everyone involved! doi.org/10.1029/2023TC…

In a new #BSSA paper led by @UUtah scientists, a team uses machine learning to explore an earthquake sequence that struck Utah's Salt Lake Valley on March 18, 2020. Their analysis suggests a different geometry to the Wasatch fault than expected. buff.ly/3KvrlH1

@synthical_ai Very cool. Personally, I prefer dark-mode for point-data figures (e.g. geographic plots of earthquake as points), but the majority of manuscript reviewers criticise dark mode figures.

@ALomaxNet Dark mode for this paper for those who read at night 🌚 synthical.com/abs/2404.05437…

New: Mapping finite-fault slip in 3D from spatial correlation between seismicity and point-source Coulomb stress change an inverse Coulomb procedure: infer finite faulting from aftershocks - works really well! Preprint: arxiv.org/abs/2404.05437 Poster: zenodo.org/doi/10.5281/ze…

@DocTerremoto Thanks Pablo! And you point about imaging clarifies alot for me - I was a bit confused why cross-correlation performed a sort of inverse. I still want to make the connection with inversion in the general sense.

@ALomaxNet Nice work. Your "pseudo-inverse" approach can be called "imaging" (e.g. Claerbout). For an inverse problem d=G*m with formal solution m=(G^T*G)^(-1)*G^T*d, imaging is the approximation m~G^T*d. The latter is the cross-correlation between G and d.
