This latest research project adopted a simple approach that involved feeding a deep learning machine with large amounts of seismic data recorded before quakes occurred.
The goal was to develop an algorithm with the ability to detect recurrent phenomena that lead up to a significant seismic event.
The machine was initially trained using laboratory earthquakes, before being adapted to look for signs of “slow” earthquakes under Vancouver Island, Canada. Seismic events of this kind, which share many characteristics with more devastating fast earthquakes, can last for a period of weeks or even months. Given that they are slow, they hardly generate any seismic waves and as a result do not usually cause much in the way of damage.
The AI agent also found that the tremors start on a very small scale and then accelerate before becoming visible to the naked eye, as they do in fast earthquakes.As it stands, there has been little progress towards this goal. “If you look at this question in terms of time scales: a slow earthquake lasts for a month, and preceding signals are detectable for 100 days in advance of the event. A high magnitude major earthquake lasts for 10 to 100 seconds, which means that preceding signals should be observed 30 to 300 seconds before it takes place…,” said Claudia Hulbert and Romain Jolivet in a layman’s explanation of their work published in The Conversation.
However, as it stands none of this has been proven, and perhaps more to the point, what would we do with a warning that comes just five minutes before a catastrophe? Hugely destructive earthquakes are also relatively rare, which means that researchers do not have enough seismic data to train an AI to predict them. Further study of the mechanics of seismic events so that they can be modeled by computers and eventually predicted appears to be the most promising research strategy for the moment.
