Exam 8: A Violent Pulse: Earthquakes

Why is an early warning system NOT considered a short-term earthquake prediction tool?

Where do earthquakes occur? Please explain your answer in the context of plate tectonics.

The point within Earth where an earthquake takes place is termed the

The moment magnitude is based on the ___________ and ___________ of the earthquake.

At any point along the surface of any nonvertical fault, as shown in the following figure, the

The recurrence of earthquakes along a single fault is referred to as

The larger the ___________ of the wave, the MORE severe the damage will be.

Seismic retrofitting is the process of

What phases of matter can a P-wave travel through? An S-wave? How has this helped us to have a better understanding of the layers of our Earth?

Vertical motion seismographs record earthquakes by producing a squiggly diagram called a

Compare and contrast P- and S-waves.

Earthquakes can often produce ___________ by breaking gas lines

S-waves are unable to pass through the Earth's outer core, which indicates that the outer core is

Explain why tsunamis are NOT tidal waves.

Earthquakes often occur along

Periods of intermittent sliding on a fault because of stress release during episodes of slip, followed by stress buildup to the point that the fault is reactivated, is termed

Early warning systems use computers to detect a nearby earthquake and send an emergency alert to warn of the event. Which seismic phase is the system detecting when it sends the alert?

Why is an empty field the safest place to be in an earthquake?
