There is no way to spot big earthquakes ahead of time
By Aylin Woodward
All earthquakes look the same when they start, making it unlikely we will be able to predict which will cause the most devastation from early observations.
Early warning systems rely on seismometers picking up tremors and sounding the alarm for nearby cities before major shaking starts. Even a few seconds’ warning can make a lot of difference, both for individual people and for organisations like hospitals, says Daniel Trugman at the Scripps Institution of Oceanography in La Jolla, California.
