Slow earthquakes: It's all in the rock mechanics

A team of seismologists has discovered that slow earthquakes, which last minutes rather than seconds, are linked to the type of rock in faults. Laboratory experiments using natural samples from Japan found that clay minerals play a key role in this slip behavior, influencing how rocks react to shear.
