Fingerprinting Slow Earthquakes And How They Relate To The Big One

The most powerful earthquakes happen at the junction of two converging tectonic plates, where one plate is sliding (or subducting) beneath the other. Now scientists have found that an anomalous layer at the top of a subducting plate coincides with the locations of slow earthquakes and non-volcanic tremors. Such a layer in similar settings elsewhere could point to other regions of slow quakes.
