Problem 1
Explain how energy is stored prior to, and then released during, an earthquake.
Problem 2
Give two mechanisms that can release accumulated elastic energy in rocks.
Problem 3
Why do most earthquakes occur at the bound. aries between tectonic plates? Are there any exceptions?
Problem 4
Define focus and epicenter.
Problem 5
Discuss the similarities and differences among
Problem 6
Explain how a seismograph works. Sketch what an imaginary seismogram would look like before and during an earthquake.
Problem 7
Describe the similarities and differences between the Richter and moment magnitude scales. What is actually measured and what information is obtained?
Problem 9
Discuss earthquake mechanisms at the three types of tectonic plate boundaries.
Problem 10
What is the Benioff zone? At what type of tectonic boundary does it occur?
Problem 11
Why do only shallow earthquakes occur along the Mid-Oceanic Ridge?
