What is a thrust fault?
A thrust fault is a reverse fault with a gently incline, or low angle of dip. If the slip on a fault is partly strike-slip and partly dip-slip, the fault is called an oblique-slip fault. • Q: What happens to a fault when an earthquakes occurs? A: Earthquakes occur on faults. When an EQ occurs on one of these faults, the rock on one side of the fault slips with respect to the other. The fault surface can be vertical, horizontal, or at some angle to the surface of the earth. The slip direction can also be at any angle. • Q: What are the names of the 2 basic earthquakes? A: Strike-slip earthquakes–occurs on an approximately vertical fault plane as the rock on one side of the fault slide horizontally past the other. Dip-slip earthquake — the fault is at an angle to the surface of the earth and the movement of the rock is up or down. • Q: How do we know a fault exists? A: (1) if the earthquake left surface evidence, such as surface ruptures or fault scarps (cliffs made by earthquakes); (2
