 Earthquakes
 To be familiar with forces that causes
earthquakes
 To describe where earthquake waves
begin and how they travel
 To identify the causes of earthquake
damage

Plate Tectonics

Landslides
Deep injection of
water in to wells
Magma moving up
toward the ground
surface
Asteroids

 Start at the
Focus
 Body waves
 Can travel
through the
“body” of the
Earth

Primary waves
 Travel through solid and
liquid (crust, mantle,
core)
 Fastest type of seismic
wave

Secondary waves
 Cannot travel through
liquid (Earth’s outercore)
 Slower than P-waves

Surface wave
 Begin at epicenter,
not focus
 Slowest type of
seismic wave
 Does the most
damage to
structures

Causes
 Duration of Shaking
▪ Ground shakes longer in higher magnitude EQ
 Distance and depth of the EQ
▪ Further away you are, usually the less damage
 Liquefaction
▪ The changing of a solid into a liquid during the period of
strong ground shaking, kind of like quicksand
 Quake lakes
▪ Form when landslides block rivers causing flooding
