 A Fault is a deep crack in the
earth’s crust, most of them are
found between two tectonic plate
boundaries.
 The San Andreas Fault is a
continental transform fault that
extends roughly 1,200 kilometers
(750 mi) through California.
 It forms the tectonic boundary
between the Pacific Plate and the
North American Plate, and its
motion is right-lateral strike-slip
 San Andreas Fault was named after
San Andreas Lake by geologist A.C.
Lawson in 1895
 The fault begins in Gulf of
California, and travels
north through Baja, past
the Salton Sea, all the way
up to San Francisco and
exit’s the bay where it
continues to run along the
coast until it ends near
Eureka, California.
 The entire San Andreas
fault system is more than
800 miles long and extends
to depths of at least 10
miles within the Earth.
 Tectonic plates are what make up the earth’s crust where
the oceans and continents rest.
 The name of the tectonic plate that sits on the east side of
the San Andreas Fault Line is the North American Plate
and on the west side is the Pacific Plate.
 The southwestward motion of the North American Plate
towards the Pacific is creating compressional forces along
the eastern side of the fault. The effect is expressed as the
Coast Ranges.
 The northwest movement of the Pacific Plate is also
creating significant compressional forces which are
especially pronounced where the North American Plate has
forced the San Andreas to jog westward.
 This has led to the formation of the Transverse Ranges in
Southern California, and to a lesser but still significant
extent,the Santa Cruz Mountains
 Age: Neogene-Holocene
 The San Andreas Fault is
a right lateral strike-slip
fault.
 It means that the left side
of the fault is moving
northward towards
Alaska while the right
side is sliding southward
toward Mexico.
 The fault divides into five segments, each with
different characteristics and a different degree of
earthquake risk.
 The most significant being the southern segment,
which passes within about 35 miles (56 km) of Los
Angeles. The slip rate along the fault ranges from 20 to
35 mm (0.79 to 1.38 in)/yr.
 Northern Segment
 Creeping Segment
 Parkfield Segment
 Central Segment
 Southern Segment
 The Northern segment of the San Andreas fault
extends from Shelter Cove to south of the San
Francisco Bay area.
 This portion of the San Andreas fault extends from San
Juan Bautista, near Monterey, to the short Parkfield
segment deep in the Coast Ranges.
 It exhibits a phenomenon called aseismic creep, where the
fault slips continuously without causing earthquakes
 This part of he fault
is at the center of the
San Andreas fault.
Hardly 30 kilometers
long, this segment is
special because it
has its own set of
magnitude-6
earthquakes that
don't involve the
neighboring
segments.
 This Segment is
defined by the great
rupture of 9 January
1857, a magnitude-8
earthquake that
broke open the
ground for about 350
kilometers from the
hamlet of Cholame
near Parkfield to
Cajon Pass near San
Bernardino.
 From Cajon Pass, this segment of the San Andreas
fault runs about 300 kilometers to its end on the
shores of the Salton Sea
 The San Andreas began to form in the mid Cenozoic about 30
Mya. At this time, a spreading center between the Pacific Plate
and the Farallon Plate (which is now mostly subducted, with
remnants including the Juan de Fuca Plate, Rivera Plate, Cocos
Plate, and the Nazca Plate) was beginning to reach the
subduction zone off the western coast of North America.
 As the relative motion between the Pacific and North American
Plates was different from the relative motion between the
Farallon and North American Plates, the spreading ridge began
to be "subducted", creating a new relative motion and a new style
of deformation along the plate boundaries.
 These geological features are what are chiefly seen along San
Andreas Fault. It also includes a possible driver for the
deformation of the Basin and Range, separation of the Baja
California Peninsula, and rotation of the Transverse Range.

The San Andreas Fault: A Geological Force Shaping California

  • 1.
  • 2.  A Fault is a deep crack in the earth’s crust, most of them are found between two tectonic plate boundaries.  The San Andreas Fault is a continental transform fault that extends roughly 1,200 kilometers (750 mi) through California.  It forms the tectonic boundary between the Pacific Plate and the North American Plate, and its motion is right-lateral strike-slip  San Andreas Fault was named after San Andreas Lake by geologist A.C. Lawson in 1895
  • 3.  The fault begins in Gulf of California, and travels north through Baja, past the Salton Sea, all the way up to San Francisco and exit’s the bay where it continues to run along the coast until it ends near Eureka, California.  The entire San Andreas fault system is more than 800 miles long and extends to depths of at least 10 miles within the Earth.
  • 4.  Tectonic plates are what make up the earth’s crust where the oceans and continents rest.  The name of the tectonic plate that sits on the east side of the San Andreas Fault Line is the North American Plate and on the west side is the Pacific Plate.  The southwestward motion of the North American Plate towards the Pacific is creating compressional forces along the eastern side of the fault. The effect is expressed as the Coast Ranges.  The northwest movement of the Pacific Plate is also creating significant compressional forces which are especially pronounced where the North American Plate has forced the San Andreas to jog westward.  This has led to the formation of the Transverse Ranges in Southern California, and to a lesser but still significant extent,the Santa Cruz Mountains  Age: Neogene-Holocene
  • 5.  The San Andreas Fault is a right lateral strike-slip fault.  It means that the left side of the fault is moving northward towards Alaska while the right side is sliding southward toward Mexico.
  • 6.  The fault divides into five segments, each with different characteristics and a different degree of earthquake risk.  The most significant being the southern segment, which passes within about 35 miles (56 km) of Los Angeles. The slip rate along the fault ranges from 20 to 35 mm (0.79 to 1.38 in)/yr.  Northern Segment  Creeping Segment  Parkfield Segment  Central Segment  Southern Segment
  • 7.  The Northern segment of the San Andreas fault extends from Shelter Cove to south of the San Francisco Bay area.
  • 8.  This portion of the San Andreas fault extends from San Juan Bautista, near Monterey, to the short Parkfield segment deep in the Coast Ranges.  It exhibits a phenomenon called aseismic creep, where the fault slips continuously without causing earthquakes
  • 9.  This part of he fault is at the center of the San Andreas fault. Hardly 30 kilometers long, this segment is special because it has its own set of magnitude-6 earthquakes that don't involve the neighboring segments.
  • 10.  This Segment is defined by the great rupture of 9 January 1857, a magnitude-8 earthquake that broke open the ground for about 350 kilometers from the hamlet of Cholame near Parkfield to Cajon Pass near San Bernardino.
  • 11.  From Cajon Pass, this segment of the San Andreas fault runs about 300 kilometers to its end on the shores of the Salton Sea
  • 12.  The San Andreas began to form in the mid Cenozoic about 30 Mya. At this time, a spreading center between the Pacific Plate and the Farallon Plate (which is now mostly subducted, with remnants including the Juan de Fuca Plate, Rivera Plate, Cocos Plate, and the Nazca Plate) was beginning to reach the subduction zone off the western coast of North America.  As the relative motion between the Pacific and North American Plates was different from the relative motion between the Farallon and North American Plates, the spreading ridge began to be "subducted", creating a new relative motion and a new style of deformation along the plate boundaries.  These geological features are what are chiefly seen along San Andreas Fault. It also includes a possible driver for the deformation of the Basin and Range, separation of the Baja California Peninsula, and rotation of the Transverse Range.
