1
Q
a threat of a naturally occurring event that will have a negative effect on humans
A
Hazards
2
Q
the negative effect resulting from a naturally occurring event
A
Disaster
3
Q
when the hazardous threat actually happens and harms humans
A
Natural Disaster
4
Q
- generated from rocks breaking along a fault, producing seismic waves
- buildings can be damaged
A
Ground Shaking
5
Q
used to tell the size of an earthquake
A
Richter Magnitude Scale
6
Q
the change of level of the ground that a structure is settling on
A
Subsidence
7
Q
- how far the surface moves during an earthquake
- can move objects fixed on the ground
- structures can be seriously damaged or ripped apart
A
Ground Displacement
8
Q
submerging on an area underwater
A
Flooding
9
Q
- huge waves of water caused by earthquakes
- capable of doing enormous damage to coastlines
A
Tsunamis
10
Q
- only a few feet high and they occur in lakeside areas
- smaller tsunamis
A
Seiches
11
Q
- soil breaks off resulting to falling rocks and debris
- can collide with people and property or block off roads and utility lines
A
Earthquake-Induced Landslides
12
Q
- swift moving mixture of water and soil
- common in areas with rich soil but little vegetation
A
Mudflows
13
Q
- mixture of soil and groundwater, developing a quicksand consistency
- can drag down the structures situated on the ground due to lack of support
A
Liquefaction
14
Q
- molten rocks exit from volcanic vents
- its consistency varies depending on the composition
A
Lava Flows
15
Q
- mixtures of pulverized rock, ash, and hot gases that move at hundreds of miles per hour
- up to 400 degrees
A
Pyroclastic Flows
