Notes from Chun-Ming Huang's research and engineering in seismic AI — the stories behind the models, loss functions, and real-world data, written to be read.
How Did AI Learn to Pick Seismic Phases?
In just a few years, AI phase picking went from every lab writing its own code to calling a pre-trained model in a single line. A plain-language tour of how that happened: PhaseNet, EQTransformer, and the SeisBench toolbox that tied the ecosystem together.

Deep-learning phase pickers have a strange quirk: the S-wave position is right, but its amplitude gets pushed below the detection threshold and counted as a miss. A plain-language look at why it gets stuck, and how BlueDisc recovers it with a shape-aware loss — a 64% gain in effective detections.
