Abstract: I will present recent and ongoing work exploring representations of the seismic wavefield – building from classical labels, such as “P-wave”, “S-wave”, or “noise”, to vector space representations of the wavefield at a single station and across an entire seismic network to encoding the seismic wavefield as a stream of integers. The key insight to my approach is learning higher-dimensional representations of seismic waves by predicting future shaking or waveforms from current waveforms. I train a suite of deep learning models, ranging from tiny models with a few thousand parameters to generative pre-trained transformer models with billions of parameters, for tasks such as earthquake detection, earthquake early warning (EEW), and earthquake waveform synthesis.

Bio: Tim Clements is a Mendenhall Fellow at the USGS Earthquake Science Center in Moffett Field, CA. He focuses on applying natural language processing, deep geometric learning, and tiny machine learning to a variety of earthquake-related problems. He received a PhD in Earth and Planetary Science from Harvard University in 2021 and a BS in Engineering from Cornell University in 2015. He has deployed seismometers in Ethiopia, Chile, Argentina, Massachusetts, Oklahoma, California, and Washington state. At ESC he is prototyping low-cost MEMS accelerometers for EEW, designing new algorithms for EEW, and extracting a seismic grammar from large earthquake datasets.
