EARTHQUAKE IMPACTS

Immediate Impacts

• The impacts to a community from earthquake events
  include injuries to citizens, damage to property,
  and the demand for public safety.
• Widespread panic and fear to the citizens living
  in the affected areas.

3
Long Term Impacts

• Creation of faults along tectonic boundaries.
• Economic failures in effected areas.
• Aftershocks, or smaller earthquakes, hit the
  effected areas and create further destruction.

Earthquake Fault Types
5
Strike-Slip Faults

• Strike-Slip faults are caused when two of the
  earths plates move adjacent to each other. This
  can cause sudden, rapid movement of the crust,
  that could destroy homes or property.

6
Normal Faults

• Normal faults are caused by two of the earths
  plates moving away from each other. Normal faults
  created the Mid-Atlantic Ridge.

7
Reverse Faults

• Reverse faults are created when two tectonic
  plates are forced together. As a result one of
  the plates is pushed upwards and creates a Drop
  Off on the surface.

8
Oblique Faults

• Oblique faults are formed when the tectonic
  plates are both moving adjacent to each other and
  moving away from each other.
