These are events which are percieved to be a threat to people, the built environment and the natural environment. They occur in the physical environments of the atmosphere, lithosphere and hydrosphere.
What is Natural Hazards?
100
Giant, sea waves generated by shallow-focus underwater earthquakes, violent volcanic eruptions, underwater debris slides and landslides into the sea
What is a Tsunami?
100
Molten rock (magma) flowing onto the surface.
What is Lava?
100
Ground shaking and ground rupture are examples of this effect.
What is a primary effect?
200
Socio-economic status, Level of education, Occupation/employment status, Religion/ cultural/ethnic background, Family & Marital status, past experience, values/personality & expectations all determine someones _____ of natural hazards.
What is perception?
200
a belt along the Pacific Ocean characterized by active volcanoes and frequent earthquakes.
What is the Ring of Fire?
200
a concentration of radioactive elements below the crust causes a hot spot to develop. A plume of magma rises into the plate above. When the lava breaks thorough active volcanoes form above the spot.
What is a Hot Spot?
200
Soil liquifecation, landslides, and tsunamis are all included in this effect category.
What are secondary effects.
300
What is the Risk Management Cycle?
300
A rapid rise in sea level in which water is piled up against the coastline to a level far in excess of the normal conditions at high tide.
What is a Storm Surge?
300
Main method of measuring the magnitude of volcanoes.
What is the Volcanic Explosivity Index (VEI)?
300
Large concrete weights on top of buildings, rubber shock absorbers in the foundation, and cross bracing.
What are examples of retrofitting buildings?
400
In 1912, he developed a theory arguing that a supercontinent existed 300 million years ago.
Who is Alfred Wegner?

What is a tropical revolving storm?
400
Most volcanic activity associated with plate tectonic processes and is mainly located along these.
What are plate margins?
400
This seismic activity took place in 2010, and the effects are still being felt today.
What is the earthquake in Haiti?
500
there are 3 different ways we measure an earthquake's magnitude but this one uses roman numerals and is based on intensity of an impact.
What is the Mercalli Scale?
500
These causes the greatest amount of damage and accounts for 75% of all earthquake energy released.
What is a Shallow Focus Earthquake?
500
Due to this eruption in 2010, large amounts of ice melted causing floods. Europe also had to shut down its airspace because of the ash cloud.
What is the eruption of Eyjafjallajökull (Iceland)?
500
A logarithmic scale used to rate the strength or total energy of earthquakes.
What is the Richter Scale?
