Geologist: Dr. Michele Cooke

Why are some faults larger than the others?

Why are some faults larger than the others?

- Brittle/Ductile

- Magnitude of Earthquakes

- Direction of extension or compression

- Age (The bigger, the older)

- Pressure (Amount/Strength)

How to tell the difference between a small and large fault

How to tell the difference between a small and large fault

- The larger the fault the larger the landmass & damage (brittle/ductile/flexibility)

- Location of corresponding bedrock layers

-Larger and Smaller faults’

EXAMPLE: Wasatch Fault (rate of increase: 4 inches per year)

-Clear fault indication means it is a young fault

-Older faults tend to have multiple cracks/breakage & bedrock layers are difficult to tell apart

-Small faults increase in size due to seismic activity

-Extension & Compression

-Length of slip

- Focus point of stress/breakage

How small faults become large faultsHow small faults become large faults

Where will we drill for oil in Moab?

-Near the Moab Fault

Examples are as follows:

Where two layers of bedrock meetWhere two layers of bedrock meet

In a fold on top of water In a fault, specifically the footwall
