Project Description
If and when an earthquake has been characterized, can shaking and tsunami amplitudes be accurately forecast for critical locations (e.g. population centers or critical infrastructure sites) on short timescales that have utility for warning? This project builds on the research group’s work on large earthquake and tsunami forecasting, using machine learning, specifically M-LARGE.
Improvements will be made to FakeQuakes, a suite of algorithms that is used to generate scenario ruptures and to simulate realistic high-rate global navigation satellite system (HR-GNSS) data used to train machine learning (ML) algorithms, such as M-LARGE. To supplement M-LARGE, a new algorithm will be developed to detect earthquakes directly from the GNSS waveforms, independent of an external trigger, which can detect early onset signals in noisy GNSS waveforms and facilitate more rapid and accurate warnings to the public.
