Preliminary finite-fault model of today’s Mw 7.7 West Flores earthquake, computed by our lab, showing a complex rupture with cascading asperities. See the waveform fits example and appreciate how complex the seismograms are

Nice one... congratzz Prof!

[Dimas Salomo J. Sianipar @SianiparDimas]

Happy to share our new publication in JVGR, highlighting the use of waveform-based seismicity analysis to better characterize the spatiotemporal evolution of swarm seismicity preceding the 2017 Mt. Agung eruption.

Our new publication!!

[Annals of Geophysics @AGeophysics]

#OpenAccessArticle | #AnnalsOfGeophysics
Deep learning reveals the structure of the 2006 Yogyakarta MW ~6.4 aftershock sequence, highlighting depth contrasts and stress-driven patterns.
Results point to a westward-dipping fault east of the Opak Fault.

The CWA Benchmark: A Seismic Dataset from Taiwan for Seismic Research #SRL

Seismology studies often use deep learning models that require benchmark datasets to train models. Here's a new one from Taiwan that contains about 500,000 seismograms!

Superb!!!

Obtaining reliable #MomentTensor solutions for small to moderate earthquakes is challenging due to significant data and theoretical errors. Our new automated procedure improves solution reliability and provides more accurate uncertainty estimates.
