Strike slip faults 1. Regional tectonic setting 2. Example: the San Andreas 3. Patterns, complexities 4. Societal importance

Dead Sea Altyn Tag - Asia A few continental examples

Transform boundaries within ocean basins

Strike slip faults- let’s start with the San Andreas

How deep should earthquakes be within an active strike-slip fault?

The North Anatolian fault-rupture near Izmit last September.

Transtension - sag ponds, pull-apart basins

The San Andreas bend near Los Angeles

Major landslides associated to strike slip motions

What is important about strike-slip faults and why do we care? 1.Commonly represent plate boundaries-single faults! 2. Vertical faults; blocks moving horizontally relative to each other. 3. Large earthquakes, no wonder since they take 5-10 cm per year of plate motions! 4. San Andreas, one of the best studied examples.
