Question

. What type of tectonic plate boundary worldwide (not just Sumatra) causes earthquake-induced tsunami?
[Convergent boundary] [Divergent boundary] [Transform boundary]

2. How many magnitude 8 earthquakes does it take to equal the energy release for a magnitude 9 earthquake according to the film?
[9] [30] [100] [900]

3. How deep under the earth's surface was this particular earthquake according to the film?
[8 km] [30 km] [978 km] [1542 km]

4. The movie spends some time talking about how a tsunami is generated. Listen to the scientists describe this process and choose the best answer from the following below:
[The sea floor moves horizontally, which in turn moves the water horizontally, generating the tsunami.]
[The sea floor moves vertically, which in turn moves the water vertically, generating the tsunami.]
[The earthquake's shockwave goes into the water, which in turn generates the tsunami.]

5. Learning what you have about how tsunami are generated by earthquakes, can the offset (movement) along the San Andreas fault during an earthquake produce a dangerous tsunami directly? (Note: This question is not answered directly in the film)
[Yes] [No]

6. The Pacific Tsunami Warning Center was able to alert the east coast of Africa about the incoming tsunami. How many fatalities occurred in Kenya as a result according to the film?
[1] [53] [1032] [100,000+]

7. Of the four causes of tsunami mentioned in the film, which produces tsunami more than any other?
[Earthquake] [Landslide] [Volcanic Eruption] [Asteroid Impact]

8 Which region of the continental U.S. has a Subduction Zone off its coast, and therefore is under the risk of a similar tsunami that occurred in Sumatra in 2004?
[Hawaii] [California] [Pacific Northwest] [Atlantic Seaboard]

9. Which ocean has more chance of a tsunami than any other: (Note: This question is not answered directly in the film)
[Indian Ocean] [Arctic Sea] [Atlantic Ocean] [Pacific Ocean]

Explanation / Answer

Question 1) convergent boundary

Reason : in the convergent boundary plates collide with each other causing earthquakes which in later induces tsunami

Question 8) California

Reason : it has cascadia subduction zone which is 1000km long

Question 9) pacific ocean

Reason : it has most number of active subduction zones which are sea floor earthquakes which are also associated with volcanic arc
