Quick Answer
The 2011 Tōhoku earthquake produced slip of more than 50 meters on parts of the fault, among the largest ever measured.
The Full Story
The 2011 Tōhoku megathrust earthquake caused extraordinary slip on the plate boundary offshore Japan. In some parts of the rupture zone, the two plates moved more than 50 meters relative to one another. That huge displacement helped generate the devastating tsunami and explains why the earthquake was so powerful. Large fault slip is a key measure in understanding why some earthquakes produce exceptional tsunamis. Tōhoku remains one of the best-studied examples of extreme megathrust behavior.
