1
How many seismometer stations must be used to determine an earthquake's epicenter (Hint: Process called Triangulation)
three or more
only two
only one
fewer than three
2
The higher the number on the Richter scale, the lower the damage.
True
False
3
Which of the following scales is used to measure earthquake strength?
gap-hypothesis scale
Earthquake-hazard scale
Richter scale
Modified Mercalli scale
4
Which of the following describes the moment magnitude of an earthquake?
the amount of movement along a fault (crack in the Earth)
the distance from the earthquake's epicenter
5
The epicenter of an earthquake is the point on Earth's surface
directly above the earthquake's focus/hypocenter
where the damage is lightest
directly below the earthquake's focus/hypocenter
where no damage has occurred
6
What is the biggest difference between the Moment Magnitude scale and the Richter scale?
The Richter measures from the focus. MM is from epicenter.
One smells like fish. The other smells like poptarts.
The MM measures from the focus. Richter is from epicenter.
7
How is the Mercalli Scale measured?
Observations from the people present
Total number of deaths from earthquake
Log scale based on size of seismic waves
Total value of damaged objects
8
What is magnitude?
an earthquake's start time
an earthquake's location
an earthquake's strength
an earthquake's intensity
9
Waves that are also known as secondary waves
S Waves
Seismic Waves
focus
P Waves
10
If you were in a car on the open road when an earthquake occurs, you should
get out of the car and stand under a tree
drive away from the area
stop the car and stay inside
crawl underneath the car
11
Which of the following is NOT a factor that determines the DAMAGE effects of an earthquake
distance from the epicenter
geology in the region
construction methods used in the reagion
distance from the focus
12
What is the moment magnitude scale based on?
The study of how many earthquakes occurred in the past
How fast the ground moves at a seismic station
The total amounts of energy released by earthquakes
The Richter scale
13
what is the richter scale
a scale that measures your awesomeness
IDK
a scale the measures the strength of an EQ by seismic waves
a scale that helps teachers grade their students
14
The intensity of an earthquake measures the effect of an earthquake
at the point of greatest magnitude
at the epicenter
at the focus
at Earth's surface
15
Waves of energy that travel through Earth away from an earthquake in all directions are called
transform waves
deformation waves
earthquake waves
seismic waves
16
Which of the following causes stress in Earth's crust?
seismic gap
earthquake hazard
tsunami wave
tectonic plate movement
17
The point inside Earth where an earthquake begins
core
focus
center
epicenter
18
Which is used to assess likelihood an area is to have a damaging earthquake in the future?
earthquake-zone level
Mercalli intensity level
seismic gap level
earthquake-hazard level
