Creating a Tsunami Early Warning System Using Artificial Intelligence

Researchers develop an early warning system that combines acoustic technology with AI to immediately classify earthquakes and determine potential tsunami risk. They propose using underwater microphones, called hydrophones, to measure the acoustic radiation produced by the earthquake, which carries ...

Ridgecrest Faults Increasingly Sensitive to Solid Earth Tides Before Earthquakes

Faults in the Ridgecrest, California area were very sensitive to solid earth tidal stresses in the year and a half before the July 2019 Ridgecrest earthquake ...

Turkey's Next Quake: Research Shows Where, How Bad -- But Not 'When'

Using remote sensing, geophysicists have documented the massive Feb. 6 quake that killed more than 50,000 people in Eastern Turkey and toppled more than 100,000 buildings. Alarmingly, researchers found that a section of the fault remains unbroken and locked -- a sign that the plates there may, when ...

Puerto Rico Tsunami Deposit Could Have Come from Pre-Columbian Megathrust Earthquake

Tsunami deposits identified in a coastal mangrove pond in Northwest Puerto Rico could have come from a megathrust earthquake at the Puerto Rico Trench that occurred between 1470 and 1530, according to new ...
