Megathrust quake faults weaker, less stressed than thought

10 septiembre 2015

Some of the inner workings of Earth’s subduction zones and their ‘megathrust’ faults have been revealed by researchers who calculated the frictional strength of subduction zone faults worldwide, and the stresses they are under. Stresses in subduction zones are found to be low, although the smaller amount of stress can still lead to a great earthquake.
