The team uses high-precision equipment to monitor the Earth's gravitational field at low frequencies, looking for abnormalities in gravitational waves that could be a warning sign an earthquake is imminent
Chinese scientists claim to have developed a groundbreaking technique to forecast earthquakes with a magnitude of 7.0 or more by monitoring the Earth s gravitational field for abnormalities in gravitational waves. While they received an ominous signal before the recent 6.2 magnitude earthquake in Gansu and Qinghai provinces, they couldn t predict the exact location.
While a massive earthquake struck Gansu - one of China's poorest regions - just before midnight on Monday, Chinese scientists say that they picked up warning signs on Friday – days before a 6.2 magnitude quake happened. Through studying nearly 500 earthquakes over the past two years, the team could now estimate the magnitude and a time frame for when the earthquake might occur. but one important part was missing., World News, Times Now
