Final Jeopardy

1 - $100n What is an epicenter?

n Location on the earth’s surface above where an earthquake occured

1 - $200n What type of tectonic plate boundary exists

where two plates move away from one another?

n Divergent boundary

1 - $300n What are the three conditions needed for

liquefaction to occur?

n i) loose granular sedimentn ii)Saturation of the sedimentn iii)Intense shaking (earthquake)

1 - $400n In general, the greater the focal depth of an

earthquake the _____ intense the shaking at the surface

n The less intense

1 - $500n What are three factors that led to the Haiti 2010

earthquake being one of the world natural disasters in history?

n Unstable governmentn Densely populated cityn Poor building materials and codesn Aftershocksn Damage to transportation links n Poor sanitary conditions/Cholera outbreak

2 - $100n Where are approximately 2/3 of volcanoes

located?

n Along the “Ring of Fire”

2 - $200n What type of volcano tends to be wider than

they are tall?

n Shield Volcano

2 - $300n What are three secondary hazards of volcanoes?

n Answer can vary: landslides, tsunamis, ash fall, pyroclastic flow, lahars, lava flow…

2 - $400n Name 3 natural service functions (benefits) of

volcanoes

n Volcanic soil, recreation (tourism, jobs), geothermal power, creation of new land

2 - $500n How do hot spot volcano chains form?

n Thin spot in the earth’s crust where the magma rises

n As the plate moves, the old, now dormant volcano moves with it

n A new volcano begins to form over the hot spot

3 - $100n What is a tsunami?

n Series of waves caused by a large displacement of a large volume of water in an ocean or a lake

3 - $200n If an earthquake occurred in Japan, what type of

tsunami would we (Vancouver Island) be watching for?

n A distant tsunamin (travels more than 3 hours or 1000km)

3 - $300n Name three ways a tsunami can be triggered

n Large earthquaken Volcanic eruptionn Landsliden Asteroid or comet impact

3 - $400n What were at least two lessons learned in the

2004 Indian Ocean tsunami?

n The need for: a tsunami warning system, better public tsunami education (what to do before, during and after), better communication, better building codes/construction practices

3 - $500n Describe the stages of an earthquake-triggered

tsunami wave

n Earthquake releases energy and causes a large displacement of water

n Tsunami travels fast in open oceann Tsunami approaches shore, friction and

shallower area causes tsunami to slow down and raise in height

n Tsunami water rushes onto shore

4 - $100n Where is Canada’s most at risk region for

wildfires?

n BC and the boreal forest

4 - $200n What are the three factors that control wildfire

behaviour?

n Fuel, topography & weather

4 - $300n What is the difference between a surface fire

and a crown fire?

n Surface fire=close to the ground, burns shrubs/leaves/grass etc.

n Crown fire=fire is in the crown of trees and can “jump” between trees easier. Harder to put out.

4 - $400n Do wildfires travel faster uphill or downhill? WHY

n Uphill! Flames are closer to the fuel source, heat rises and preheats fuel, wind current tend to go uphill

4 - $500n What are two lessons learned in the 2016 Fort

McMurray wildfire?

n Obeying evacuation ordersn Alternative evacuation routes neededn Clearer communication systemsn Removal of excess fueln Fire smart homesn Gas in vehiclesn Emergency plans (personal, local)

5 - $100n What type of hazard affects more people in

Canada & the US than any other natural hazard?

n Droughts

5 - $200n What are two factors expected to increase global

landslides?

n Urbanizationn Deforestationn Changing Global Climate

5 - $300n Name three ways a drought can negatively

effect a population

n Dust storms & related erosionn Famine/hungern Ecosystem damagen Population migrationsn Reduced electricity productionn Shortage of water for industrial usersn Social unrest, possibly war

5 - $400n Name two reasons why Cape Town, South Africa

is experiencing water shortages

n Little to no rain for monthsn Growing population n Climate change

5 - $500n Name four factors that have led to Rio de

Janeiro, Brazil experiencing so many landslides

n City is surrounded in tall granite peaksn Periodically overwhelmed by intense rainn Cut-and-fill construction methodsn Vegetation removal

Final Jeopardyn Name 3 of the 5 natural disaster trends

n Disasters are becoming more costlyn The number of people affected by disasters is

increasing n The number of disasters is increasingn The number of people dying from disasters is

decreasingn Undeveloped countries are disproportionately

affected by disaster consequences
