GLGY 202 Lecture Notes - Lecture 1: Fault Gouge, Speleology, Seismology
Document Summary
Geologists who specifically study earthquakes are called ____________: seismologists, vulcanologists, paleontologists, speleologists. Earthquakes are a result of ____________: a sudden change in atmospheric pressure, mantle upwelling, erosion lithosphere- plate movement. Faults that have moved recently or are likely to move in the future are referred to as. ____________: passive, active. Movement on a fault may occur without generating earthquakes. true. A surface along which rock on opposed sides is offset by earthquake- induced slip is called a. Ans: b: strike slip, thrust the explosion of a volcano, a giant landslide. The quantity of offset that occurs along a fault is termed ____________: displacement fault gouge the fault gauge, accumulation. If, during an earthquake, a footwall slides upward relative to a hanging wall, the fault is termed ____________. A fault cannot slip forever because __________ : normal, reverse. Ans: b: strike slip, thrust false. All discovered faults are likely to experience earthquakes in the next few hundred years.
