8Regarding earthquakes, the (blank) is the point on earth's surface directly above the point of initial rupture.
- Afocus
- Bfault scarp
- Cepicenter
- Dintensity
9The Moment Magnitude scale is logarithmic, which means as you increase from one integer to the next (for example, from a M5 to a M6), there is [blank_start]10[blank_end] times the displacement and [blank_start]32[blank_end] times the energy released.
- A10
- B32

15The fastest moving seismic body waves, which can move through solids, liquids, and gases are known as:
- AS waves
- BF waves
- Csurface waves
- DP waves
16As seismic waves move through different kinds of soil deposits, they can be slowed down. When they are, the energy that was once directed forward is transferred to the vertical motion of the surface waves. This effect is known as:
- Amaterial amplification
- Battenuation
- Cdirectivity
- Delastic rebound
17INTRAPLATE earthquakes in the US are generally more damaging and felt over much larger area than similar magnitude earthquakes in California. This is because the rocks in the eastern US are generally more solid and less fractured & they can more efficiently transmit earthquake waves.
- AVerdadero
- BFalso
18During earthquakes (usually M5 or greater) intense shaking can cause a near surface layer to water-saturated sand to change rapidly from a solid to a liquid. This phenomenon is called:
- Aliquefacation
- Bmaterial amplifacation
- Cfluid attenuation
- Dsubduction
19When earthquakes are very deep in the lithosphere, much of the energy can dissipate before the vibrations are felt at the surface.
- AVerdadero
- BFalso
20Most tsunamis are produced by the sudden HORIZONTAL displacement of the ocean floor.
- AVerdadero
- BFalso
21Of the hazards listed below, which one will NOT trigger a tsunami?
- AVolcanic eruption/collapse
- BM 7.5 or greater earthquake
- Cimpact of an extraterrestrial object
- Dhuman -induced climate change
22Tsunami can be just one wave, but are usually a series of waves that arrive at the coastline over a period of hours.
- AVerdadero
- BFalso
23In the open ocean, tsunamis travel at about (blank) miles per hour.
- A28
