Movie Worksheet for San Andreas
1.
Where does the first major earthquake of the movie occur? How do the scientists in the movie interpret this event in the context of plate tectonics?
the first major earthquake occurs at the Hoover Dam. The scientists in the movie interpret this event in the context of plate tectonics, explaining that it is a result of the San Andreas Fault slipping.
2.
What signal does the science team from Caltech use that warns them of earthquakes that are about to occur?
the science team from Caltech uses a system that monitors electromagnetic
pulses as a signal warning of earthquakes.
3.
List at least 3 types of earthquake-caused catastrophes that lead to loss of life in the movie
Building collapse, tsunamis, after shock and secondary hazards
4.
After several major earthquakes have already rocked California, the
scientists predict that the earthquakes are not yet over. What is their explanation for the movement on the fault that will lead to the final magnitude 9.6 event in northern California?
They attribute this impending catastrophic event to the movement of the tectonic plates along the San Andreas Fault.
5.
At the end of the movie a news reporter warns that the massive earthquakes along the San Andreas fault might trigger earthquakes elsewhere in the world. Based on what you know about earthquakes
and plate tectonics, does this seem realistic to you? Why or why not? (
Note – your answer to this question doesn’t need to be ‘correct’, but you need to provide an answer and describe your reasoning.
)
The idea that massive earthquakes along the San Andreas Fault could trigger
earthquakes elsewhere in the world is not realistic based. Earthquakes are primarily localized events that result from the release of stress along faults, where tectonic plates interact. While a large earthquake can redistribute stress in the Earth's crust locally, the notion that it would trigger earthquakes
on a global scale is not supported by scientific evidence.

The Chocolate Crumb Mystery
Explosions ignited by electrostatic discharges (sparks) constitute a serious danger in
facilities handling grain or powder. Such an explosion occurred in chocolate crumb
powder at a biscuit factory in the 1970s. Workers usually emptied newly delivered sacks
of the powder into a loading bin, from which it was blown through electrically grounded
plastic pipes to a silo for storage. Somewhere along this route, two conditions for an
explosion were met:
1. The magnitude of an electric field became 3.0 x 106 N/C or greater, so that
electrical breakdown and thus sparking could occur.
2. The energy of a spark was 150 mJ or greater so that it could ignite the powder
explosively.
Let us check for the first condition in the powder flow through the plastic pipes.
Suppose a stream of negatively charged powder was blown through a cylindrical pipe of
radius R = 5.0 cm. Assume that the powder and its charge were spread uniformly
through the pipe with a volume charge density…

B) A 60-Hz generator is supply ing 60% of P max to an infinite bus through a reactive network.
A fault occurs which increases the reactance of the network between the generator internal
voltage and the infinite bus by 400%. When the fault is cleared, the maximum power that can
be delivered is 80% of the original maximum value. Determine the critical clearing angle for
the condition described.
