Scientists have reported that there were 10 times more earthquakes in Southern California than previously thought.
The study published in the journal Science features a list of earthquakes that happened in the last decade, discovered as a result of better technology. Between 2008 and 2017, more than 180,000 small earthquakes had been detected, but after reviewing the data with improved technology, scientists discovered there are 10 times the amount – about 1.8 million.
Researchers at the California Institute of Technology and the University of California, San Diego note that it is very difficult to detect an earthquake and differentiate it from other movement, like a truck going by. For the study, researchers consulted more than 400 seismic sensors in the state and used computer models to search the data for patterns of earthquakes.
