ML SYSTEMS COULD DETECT DEADLY EARTHQUAKES SWIFTLY Posted on : May 20 - 2022

Researchers have now trained a machine learning system to detect earthquakes using tiny gravitational signals, showing how they may be used to pinpoint the position and extent of a major quake in near-real-time. Earthquakes have the power to alter Earth’s gravitational field at a colossal scale.

Scientists say this is a significant step towards developing a warning system for the world’s most powerful earthquakes, according to May 11 research published in Nature.

GRAVITY SIGNALS ARE USED TO TRAIN MACHINE LEARNING

A system like this might be abletect earthquakes and could help solve a massive problem in seismology: Determining the correct magnitude of a massive quake as soon as it happens, according to Andrea Licciardi, a geophysicist at the Université Côte d’Azur in Nice, France. It’s considerably more difficult to deliver timely and effective hazard warnings if you don’t have that ability which is vital because it could save thousands of lives.

The shaking and quivering transmit seismic waves through the ground, which are detected as large wiggles on seismometers after large earthquakes occur. However, current seismic wave-based systems that we use to detect earthquakes have difficulty distinguishing between magnitudes 7.5 and 9 in the few seconds following an occurrence. Geophysicists are not the only ones to utilize artificial intelligence in their research, chemists developed a new ML framework to improve catalysts. View More
