QUESTIONS AND ANSWERS GRADED A+
2025/2026
Which plate boundary type is most likely to have earthquakes that generate large tsunamis? -
ANS -subduction zones
-transform
-divergent
-collision
answer: subduction zones
Where would be the safest location during a subduction zone earthquake?
Assume the same building height and construction in all locations. - ANS -at the beach
-in the center of a valley full of sediment
-(answer) on a flat area of bedrock that is not saturated
-all of these would be equally safe
If all saturated, which of the following would be most likely to experience liquefaction during an
earthquake? - ANS -(answer) sand
-basalt

,-granite
-limestone
If you are in a region affected by an earthquake, shaking is likely to be greatest in which of the
following settings? - ANS -(answer) a river valley full of sediments where the water table is
near the surface
-on sand dunes where the water table is deep below the surface
-on the side of a sandstone hill
-at the top of a gneiss mountain
Which of the following is true of tsunamis? - ANS -(answer) wave height is tallest in shallow
near shore environments
-they can be caused by tidal action
-tsunamis are isolated (single-wave) events and never followed by secondary waves
-the wave height is largest at sea in deep water
Compared to wind-generated waves, tsunami waves in the open ocean (away from shore) are: -
ANS -have a shorter period (time between waves)
-(answer) much faster
-much taller (larger amplitude)
An earthquake of the same magnitude in California, USA and Turkey would result in: - ANS -
the results in terms of casualties would be about equal
-(answer) more casualties in Turkey because of the lack of earthquake resistant building
practices
-more casualties in California because of a higher population density

, The epicenter of the 1895 Mexico City earthquake was actually not anywhere near Mexico City.
The primary reason shaking was so much greater in Mexico City was: - ANS -the earthquake
generated a large tsunami
-the epicenter of the earthquake was in the densely populated downtown area
-(answer) the saturated lakebed sediments the city is built on
-the hard bedrock the city is built on
Most earthquake-related fatalities are due to: - ANS -(answer) shaking-related damage to
structures
-tsunamis
-landslides
-people falling into earth fissures (cracks)
The hazard of liquefaction can be reduced by: - ANS -(answer) all of the other answers would
work
-replacing sediments that tend to liquefy with stronger material
-draining sediments
-strengthening sediments with cement
The deepest earthquakes occur at: - ANS -(answer) subduction zones
-mid-ocean ridges
-collision boundaries
-transform boundaries
Liquefaction occurs: - ANS -(answer) when saturated shallow sediments are shaken
-all of these
-only when earthquake magnitudes exceed 7
