Tell them there are different kinds of faults (strike-slip, normal, and reverse faults). If you have pictures of faults and fault ruptures, now is a good time to share them with your students.

New research suggests that strike-slip faulting, the type of motion common along the well-known San Andreas Fault, California, possibly occurs also on Titan, Saturn's largest moon.

Generally, these ruptures move along the surfaces of faults more slowly than shear waves do. (Shear waves travel at about 7,800 mph (12,600 km/h)).

However, anhydrite, a mineral created by the evaporation of seawater, and other similar minerals, can become smeared along the shear zones of the fault and clog fluid flow, acting as a pressure seal.

The first studies of the 28 March 2025 magnitude 7.8 Myanmar earthquake suggest that the southern portion of its rupture occurred at supershear velocity, reaching speeds of 5 to 6 kilometers per ...

It is comparable to the roughly 400-kilometer-long 1906 San Francisco rupture, but longer than the 2023 East Anatolian Fault earthquake in Türkiye and the 2002 Denali earthquake in Alaska.

Strike-slip faulting, the type of motion common to California’s well-known San Andreas Fault, was reported recently to possibly occur on Titan, Saturn’s largest moon. New research, led by ...
