PROVIDENCE, R.I. [Brown University] — When the rigid plates that make up the Earth's lithosphere brush against one another, they often form visible boundaries, known as faults, on the planet's surface. Strike-slip faults, such as the San Andreas Fault in California or the Denali Fault in Alaska, are among the most well-known and capable of seriously powerful seismic activity.
