1) High magnitude natural disasters tend to occur __________ small scale natural events.

A.   more frequently than 

B.   less frequently than 

 C. as much as 

 

2)Match each scenario to the correct type of hazard effect. Either secondary, primary, or tertiary

 

Tsunami triggered as a result of an earthquake primary Pyroclastic flow during a volcanic eruption __________

 

Cholera outbreak in a camp of people displaced by a volcanic eruption____________

 

Fires ignited by a lava flow_____________

 

 

3) During an earthquake, seismic waves are released.

surface waves or body waves are the fastest?

4) surface waves or body waves are the most destructive.

 

5) How hot are these volcanic hazards? Consider high temperature as >150°C and low temperature as <150°C.

Lava flows: (High, any, or low)

Pyroclastic flows: (High, any, or low)                                          

Tephra/ashfall:   (High, any, or low)                                                      

Lahars:        (High, any, or low)                                          

Volcanic gas: (High, any, or low)

 

6) Rank these volcanic hazards from fastest moving to slowest.

               low viscosity lava flow    high viscosity lava flow           lahar              pyroclastic flow                     

 

7) Which of these would NOT cause a tsunami?

 a.  none; all of these could cause a tsunami 

b.   hurricane 

c.  earthquake 

d. landslide 

 

8) One cubic foot of water weighs about 62 pounds. To approximate the tsunami that caused the meltdown of the Fukushima nuclear power plant in 2011, a wall of water 45 feet high, 5,280 feet (1 mile) wide, and only 2,640 feet deep would weigh _____________ pounds

 

9)The largest animal in the world is the blue whale, which weighs about 173 tons (346,000 lbs). The impact of the tsunami from the previous question is equivalent to being hit with __________ blue whales

 

10) If you were in charge of deploying more DART II buoys in the Atlantic (which detect tsunamis), where should you position them to maximize the amount of time cities from the previous question have to evacuate?

A.   in the middle of the Atlantic 

B.   near the cities that already have time to evacuate 

C. near the La Palma Volcano 

D,   near the cities that currently don't have time to evacuate
