a. People first notice the quakes with
the movement of the glasses of water on the table. What value on
the Mercalli Scale do you think this is? What about pictures falling
off walls, the fall of the church tower, etc.?
b. When buildings begin to collapse,
notice that only brick buildings are falling. What are the differences
between brick and wooden buildings and why do earthquakes make one
fall more easily than the other?
c. People begin panicking and rush chaotically
out of the gymnasium. Was this the right thing to do? What should
you do when you experience an earthquake? Why is remaining calm
important?
