Recent studies show that 2 million hidden earthquakes have occurred between 2008 and 2017.
Washington: According to a recent study, scientists have identified nearly two million unidentified tiny earthquakes that occurred between 2008 and 2017. The study was published in the Journal of Science.
The new data reveals that there are about 495 earthquakes occurring at an average of roughly three minutes apart. Previous earthquake cataloguing had suggested that approximately 30 minutes would elapse between seismic events.
These quakes are so small that they can be difficult to spot amid the background noise that appears in seismic data, such as shaking from automobile traffic or building construction. “It’s not that we didn’t know these small earthquakes were occurring. The problem is that they can be very difficult to spot amid all of the noise,” says Zachary Ross, the lead author.
