Earthquakes happen here, and no, the answer is not at faults.
What are plate boundaries?
100
The first, the fastest.
What is a Primary Wave?
100
The paper that measures.
What is a seismogram?
100
The fire is what destroyed San Francisco in this year.
What is 1906?
100
The greatest earthquake threat for California is along the San Los Angeles Fault.
What is false - San Andreas Fault?
200
This is below the surface, this is at the surface, both are stated with a quake.
What is below the surface - focus?
What is at the surface - epicenter?
200
The spot where seismic waves originate.
What is the focus?
200
The Richter Scale's scale.
What is from 0-9?
200
The type of soil and type of place needed for liquefaction to occur.
What is loose sediment, and what is near a body of water - like an ocean? (AKA - The Bay Area)
200
Shallow focus earthquakes are common at which type of boundaries?
A. Transform only
B. Divergent only
C. Transform & Divergent
D. Transform & Convergent
What is C - Transform & Divergent?
300
When this can no longer be stored, earthquakes happen.
What is elastic strain?
300
These can only travel through solids.
What are S-Waves (Secondary), and Surface Waves?
300
Today, scientists use this to get an accurate measurement of just how much energy has been release.
What is the Moment Magnitude Scale?
300
All 4, post-earthquake hazards.
What are fire, landslides, liquefaction, and tsunamis... oh my?
300
Particles either move side-to-side swaying motion, or a rolling motion as a result of this wave.
What is surface wave?
400
An example of an earthquake that did not occur in a traditional "earthquake" zone.
What is the New Madrid Earthquake of 1811 - no plate boundary in the middle of the United States (buried faults deep in the continent, they think caused it).
400
Places on our Earth that don't receive any seismic waves, thanks to that core of ours.
What are shadow zones?
400
As you go closer, this increases. As you move farther way, this decreases.
What is the intensity/shaking of the earthquake?
400
The type of earthquake movement mandatory for a tsunami to occur.
What is a sudden up or down movement of the sea-floor, called a Normal or Reverse Fault.
400
Plates store this energy. They release this energy.
What is they store elastic/potential energy? They release kinetic energy?
500
Our closest, most recent epicenter.
What is Milpitas? (Remember the earthquake a few weeks back?)
500
Show me, with your arms, the movement of all three quakes.
What is (see Mr. Trapp for arm confirmation)?
500
The mathematical difference of how much more powerful a 3.0 earthquake is than a 1.0
What is 1000 times more powerful?
1.0-2.0 = 10x10 = 100
1.0-2.0-3.0 = 10x10x10 = 1000!
500
3 Ways to make your building earthquake resistant.
What are: Use flexible moorings (steel plates with flexible rubber), adding steel rods/reinforcing the building, base isolation (like on Smash Lab), pile foundation, and foundation anchoring.

Mercalli would have been impressed we filled out one of these in class, thanks to Donovan's observations.
What is a Shake Map, also called an Intensity Map?
