EARTHQUAKE IMPACTS

Brian Walker

Immediate ImpactsImmediate 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.

Long Term ImpactsLong 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 TypesEarthquake Fault Types

Strike-Slip FaultsStrike-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.

Normal FaultsNormal Faults• Normal faults are

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

Reverse FaultsReverse 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.

Oblique FaultsOblique Faults• Oblique faults are

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