2.7 Earthquakes - Destruction Prediction Test Questions and Answers Rated A
1. In 1872, the Lone Pine earthquake (M ~7.8) oc- Footwall, Fault, Hangning wall
curred along a big normal fault in central Cali- (from top to bottom)
fornia. Geologists looking for clues of an earth-
quake on a normal fault in the landscape begin
by asking these types of questions:
-Which parts of the landscape seem to have
moved up versus down in a relative sense?
-Is there a distinct, linear feature anywhere that
might be a fault trace or plane?
-If so, what is the orientation of the plane?
-Does the linear feature seem to separate an
uplifted area on one side from a down-dropped
area on the other?
-If so, which side is the hanging wall versus the
footwall?
-How did they move relative to each other?
Use your knowledge about earthquakes, fault
planes, and the relative motion of adjacent
crustal blocks (hanging wall, footwall) to label
features present in the landscape in the Gigapan
image below.
2. Use your knowledge about how fault motion answer in pic.
occurs and how fault scarps form to place the
following events in sequence from oldest to
youngest.
3. Use your knowledge about fault zones, their -Fault scarp creation, erosion, and
scarps, how related erosion and deposition associated sediment preservation
processes evolve over several earthquake cycles, in the geologic record is a key
and seismic map patterns to identify the correct process used in paleoseismological
