Definitions:

Strike-Slip Fault

A type of fault where the movement is predominantly horizontal, caused by shear stress, often resulting in earthquakes.

Asymmetric Fold

A geological fold where the two sides are uneven or asymmetrical, typical in areas of complex tectonics.

Subduction Zone

A region of the Earth's crust where two tectonic plates meet and one is forced below the other into the mantle, leading to volcanic activity and earthquakes.

Tilted Blocks

Geologic structures formed by the tilting of rock layers, often due to tectonic forces, creating an angle with the horizontal.
