Scientists have found that just a few seconds of warning before an earthquake hits can make a big difference. People have time to get to a safer location, surgeries can be stopped and other protections can be implemented. While early warning systems exist, many areas prone to earthquakes don’t have them because the technology is still very expensive.
A group of researchers that has been working on the West Coast’s $145 million ShakeAlert earthquake early warning system, which uses both GPS and seismometers, has come up with a solution that uses technology many of us already have in our pocket to deliver early earthquake warnings to areas that can’t afford expensive systems.
