New technology helps predict earthquakes

According to a study published in the July 11 issue of the journal Nature, American scientists have found a way to measure seismic wave frequency changes, helping build an early warning system for dynamic battles. land.

In experiments conducted in Parkfield, California, USA, scientists measured different frequencies of shear waves, called "S-waves" , at a time before, during and after two matches. Small earthquakes occurred in this area in December 2005. They discovered an unusual sign of S waves before each earthquake.

This sign appeared about 10 hours before the first earthquake occurred and in the second earthquake, which occurred 5 days later, an unusual sign appeared two hours earlier.

Laboratory studies show that S waves have very different frequencies in intensity, depending on the opening and closing of cracks in the ground.

Scientists believe that based on this difference, it is possible to create an "intensity meter" to predict the strength of earthquakes.
