What are folds?
Synclines and anticlines
are types of this
Row 1, Col 1
What are S waves?
This type of seismic wave
arrives second
at a seismograph
1,2
What is a seismograph?
This instrument is used
to measure and
record ground movement
during an earthquake
1,3
What is liquefaction?
This process occurs when an
earthquake’s shaking turns
loose soil into mud
1,4
What is tension?
This stress force
stretches rock
2,1
What is an epicenter?
This point is located on
Earth’s surface directly above
an earthquake’s focus
2,2
What are instruments uses to monitor movement along faults?
Tiltmeters, creep meters,
laser-ranging devices,
and GPS satellites are
instruments that do this
2,3
What are tsunamis?
Undersea earthquakes displace
water that may produce these
2,4
What is a reverse fault?
This fault forms when
the hanging wall moves
up past the footwall
3,1
What is the moment-magnitude scale?
This rating system
estimates the total
energy released
by an earthquake
3,2
What is a creep meter?
This instrument uses a wire
stretched across a fault to
measure horizontal movement
3,3
What is a base-isolated building design?
This design reduces
the amount of energy
that reaches the building
during an earthquake
3,4
What is stress?
Shearing, compression,
and tension are three
types of this
4,1
What are instruments used to measure earthquakes?
The Mercalli scale,
the Richter scale, and the
moment magnitude scale
are examples of this
4,2
What is friction?
The force that opposes
the motion of
one surface as it moves
across another surface
4,3
What are drop, cover, and hold?
The best way to protect
yourself during an
earthquake is to do this
4,4
What is shearing?
This type of stress pushes
masses of rock sideways
in opposite directions
5,1
What is triangulation?
The process by which geologists
draw circles to show distances
from three seismographs
is known as this
5,2
What is a seismogram?
Pattern of lines that
is the record of an
earthquake’s seismic waves
5,3
What are the causes of earthquake damage?
Shaking, liquefaction,
aftershocks, and tsunamis
are examples of this
