Faults, Earthquakes, and Tsunamis

These are vast pieces of rocks that make up the Earth's crust.

• faults

• tectonic plates

• crust

• mantle

These are fractures that are found at the boundaries of tectonic plates

• crusts

• mountains

• dips

• faults

This is called the trace of a fault.

• fault line

• dip

• block

• hanging wall

A type of fault formed by tensional stress that pull rocks apart.

• abnormal fault

• normal fault

• reverse fault

• thrust fault

A type of fault formed by compressional forces that oush the plates towards each other.

• reverse fault

• oblique fault

• normal fault

• Horst and Grabens

A type of fault whose dip is less than 45 degrees

• normal fault

• oblique fault

• thrust fault

• reverse fault

A type of fault characterized by alternating uplifted and down-dropped blocks.

• reverse fault

• oblique fault

• normal fault

• Horst and Grabens

A type of fault resulting in the sideways movement of blocks of rocks.

• thrust fault

• strike-slip fault

• reverse fault

• Horst and Grabens fault

A type of fault that has both the dip-slip and strike-slip components.

• reverse fault

• normal fault

• oblique fault

• Horst and Grabens fault

It is the vibration/shaking of the earth's surface

• tsunami

• typhoon

• earthquake

• tornado
