Which fault is known for producing the largest earthquakes in the world?
Quick Answer
Subduction-zone faults, especially megathrust faults like the one off Japan in 2011, produce the world’s largest earthquakes.
The Full Story
The largest earthquakes on Earth usually occur on megathrust faults at subduction zones, where one tectonic plate slides beneath another. These faults can rupture over enormous areas and generate magnitude 9 or greater earthquakes. A famous example is the 2011 Tōhoku earthquake off Japan, which had a moment magnitude of 9.0 and triggered a devastating tsunami. Because of their size and tsunami potential, megathrust faults are closely monitored by geoscientists.
