Prelab: Faulting, Earthquakes, & Preparedness Prelab Report
Complete your responses in a
color other than black or red
.
Part 1: Deformation
1.
How many layers of "sediment" should you place in a squeeze
box?
3-4 layers.
2.
What type of faulting occurs in the first compression of the
squeeze box in video 1.1?
Reverse
3.
What are the two main ways that the Earth responds to
compression?
Faulting or folding.
4.
How is the squeeze box model similar to
and
different from real-
world deformation of Earth’s crust?
[Consider materials, timing,
styles of deformation, etc.]
Crustal formation in the tectonic plates, it also uses real material found in the crust.
Part 2: Earthquake Forecasting
1.
What is earthquake forecasting?
Short-term earthquake prediction.
2.
Can the location, date, or time of earthquakes be predicted?
The precise location, no. Though it is generally close to predictions.
Part 3: Earthquake Simulations
1.
Describe the progression and dissipation of the earthquake you
observed in
video 3.1
.

Deformation, Earthquakes, & Preparedness Prelab Report
2.
What differences did you observe between the magnitude 4.0
and 9.0 simulations in
video 3.2
?
3.
What locations are the safest during an earthquake? (Hint: you
may want to look it up!)
Part 4: Earthquake preparedness
1.
Which background did you read?
At home
______ Berkeley Seismo Lab:
http://seismo.berkeley.edu/~rallen/seishaz/prepare/
______ Earthquake Country Alliance:
http://www.earthquakecountry.org/sevensteps/
2.
What general information is important to include in an earthquake disaster plan? List
at least (5) items.
-Stay under a table or other form of shelter
-Know where the nearest first aid is.
-Be aware of surroundings and objects that can fall and cause harm.
-Know the locations of household appliances that should be turned off (gas valves and
water boiler)
-Stay tuned to radio/news to see the damage and await instruction.
Part 5: Layers of the Earth, MooMooMath and Science
1.
What are the names of the compositional layers of the Earth?
Crust, mantle, core.
2.
What are the names of the mechanical layers of the Earth?
Lithosphere asthenosphere, mesosphere, outer/inner core.
3.
Approximately how thick are each of the following layers: crust, mantle, outer core,
inner core?
2
Deformation, Earthquakes, & Preparedness Prelab Report
Crust (0-45km) Mantle (45-2900km) Core(2900-6371km)
4.
Which is more dense: Oceanic Crust or Continental Crust?
Oceanic.
5.
What temperature does the inner core reach?
9,000-13,000 Fahrenheit.
6.
Convert the temperature from question 5 to degrees Celsius. Use the following
formula and show your work: (
°F
− 32) × 5/9 =
°C.
4,982.22 to 7,216.67 degrees Celsius.
7.
In comparison, how hot is the surface of our sun, in degrees Celsius? (Hint: look it
up)
5,500 Celsius
