Faults and Earthquakes
Terms in this set (44)
What caused seismicity
Point at the depth where the rocks ruptured to produce earthquakes; place where quake waves originate
Point on Earth's surface directly above an earthquake's focus
The block of rock that forms the upper half of a fault.
The block of rock that forms the lower half of a fault
line where the fault/fracture intersects the surface
a cliff created by movement along a fault. it represents the exposed surface of the fault prior to modification by weathering and erosion
Dip slip faults
fault blocks move up and down, creating a hanging wall and a foot wall
A type of fault where the hanging wall slides downward; caused by tension in the crust
a reverse fault in which the hanging wall slides over to the foot wall.
a type of fault where the hanging wall slides upward; caused by compression in the crust
a type of fault where rocks on either side move past each other sideways with little up or down motion
an elastic wave in the earth produced by an earthquake or other means.
two types of body waves
primary and secondary
Two types of surface waves
Love waves and Rayleigh waves
seismic waves that travel through the Earth's internet
seismic waves that travel along the Earth's surface
travel through solids and liquids. The fastest waves.
(Move like slinky or rope) only travel through liquid
Do body or surface waves cause the most structural damage to buildings?
Surface waves: side to side
cause the ground to move with an elliptical, rolling motion
stop-start movement along a fault plane caused by friction, which prevents movement until stress builds up sufficiently
elastic rebound theory
The theory that continuing stress along a fault results in a buildup of elastic energy in the rocks, which is abruptly released when an earthquake occurs.
Do rocks have infinite strength?
What happens to seismic waves as they travel out from the epicenter
A permanent change in shape or volume, in which a material breaks or cracks.
The bending and flowing of a material (without cracking and breaking) subjected to stress.
What depth is the transition from brittle to ductile deformation
What town in California experiences fault creep along San Andreas fault
San Juan Bautista
Hazards associated with earthquakes
building collapse, fire, tsunami, landslides
What caused the December 26, 2004 Tsunami near Sumatra
A powerful undersea earthquake that struck off the coast of Sumatra island
Did they have a tsunami warning system in the Indian Ocean before Boxing Day?
Is there tsunami warning system in the Pacific Ocean
Yes but it's not the best
IS NEW MADRID MO ON A PLATE BOUNDARY?
No - but it is still settling
Was the 1989 Loma Prieta earthquake due to the San Andreas Fault
Was the 1906 San Fran earthquake due to the San Fran Fault?
Has Charleston SC ever experienced large earthquakes
Is Charleston SC on a plate boundary
What other hazard caused additional devastation to the city
Was the 1994 Northridge earthquake due to the San Andreas Fault?
Did the 1964 prince William sound earthquake cause a tsunami?
What type of plate boundary led to the 1964 Prince William Sound
What was extraordinary about the 1960 Chile Earthquake
Largest ever recorded
