Artificial Intelligence assisted Ground-Motion Simulation

Abstract 

Artificial Intelligence (AI) and Machine Learning (ML) are buzzwords that get thrown about quite a bit, sometimes recklessly in an effort to increase research clout. However, there are genuine advantages to these new computational techniques, most of which are just a new spin on familiar signal processing, curve fitting and optimisation procedures. Like many other disciplines, ground motion simulation has benefitted from the application of these new tools.

In this talk, I will introduce some of the philosophical underpinnings of AI/ML: what it is, how it works, and why you might like to try it for yourself. I will then describe recent contributions that exemplify the three A’s:

  1. Automating earthquake detection and quality classification.
  2. Accelerating ground motion simulation performed by computationally intensive physics engines.
  • Aha!” – the discovery of unrecognized patterns in data.

Finally, I will conclude with a few suitably optimistic comments about future trends in AI/ML and that could lead to on-demand, operational ground motion simulation for disaster response.
