Chapter 3 Earthquakes
Typical Student Misconceptions
(from serc.carleton.edu/NAGTWorkshops/intro/misconception_list.htm)
- Earthquakes are rare events
- The ground cracks open during an earthquake to swallow people and buildings
- Earth shaking is deadly
- Seismic waves involve long distance net motion of particles
- Seismic waves go from crust to core, but not core to crust
- S-waves do not reach other side of Earth from where earthquake originated because they cannot pass through oceans (or cannot reach islands)
- Wind blowing through subterranean passages causes earthquakes
- Earthquakes occur from collapse of subterranean hollow spaces
- The biggest earthquake is a magnitude 10

C) Great earthquakes can have a magnitude of 8 or higher.
D) Over a million earthquakes of magnitude 2-2.9 is felt per year.
