1. Normal Faults
1a.
Draw/make a diagram
of a Normal fault.
1b. Name two major faults in two different countries/areas that are Normal faults. You
should name the fault and state the country it is found in.
-
Corinth Rift located in Greece is an example of a normal fault. It is between the Aegean
Sea plate and the Eurasian plate
-
The Humboldt fault zone is another example of a normal fault and it is located in the
United States of America.
1c. What size (magnitude) and when was the largest earthquake known to have occurred
on one of the faults you mentioned in 1b in the last 500 years?
-
The largest earthquake to have occurred on the Humboldt fault zone is a 5.5 magnitude
quake in Manhattan, Kansas in 1867.
2. Reverse Faults
2a. Draw / Make a diagram of a Reverse fault.
2b. Name two major faults in
two different countries/areas
that are Reverse faults. You should
name the fault and state the country it is found in.
-
The Rocky Mountains are an example of a reverse fault in the United States of
America.
-
The Himalayan Frontal Thrust is an example of a reverse fault and is located in
India but extends throughout Asia.
2c.
What size (magnitude) and when
was the largest earthquake known to have occurred on
one of the faults you mentioned in 2b in the last 500 years?
-
The largest earthquake to occur on the Himalayan Frontal Thrust was of 8.4 to 8.6
magnitude in 1950.
3. Strike-Slip Faults
3a. Draw / Make a diagram of a Strike-Slip fault.
3b. Name two major faults in
two different countries/areas
that are Strike-Slip faults. You
should name the fault and state the country it is found in.
-
The East Anatolian Fault is a right-lateral strike-slip fault in eastern Turkey.
-
The Alpine Fault is a strike-slip fault in New Zealand.
3c.
What size (magnitude) and when
was the largest earthquake known to have occurred on
one of the faults you mentioned in 3b in the last 500 years?
-
The biggest earthquake to have occurred in the Anatolian fault zone occurred in 1668 and
was a 7.8 to 8.0 magnitude quake.

4. Using the USGS website
We learned that there are 3 different types of plate boundaries.
For each of the different types, you need to capture/screenshot an image of the area where the
plate boundary occurs.
(a) Name the type of plate boundary shown in your figure.
-
Mid-Atlanitc Ridge/Divergent Plate Boundary
(b) how many
earthquakes are displayed on your map
-
There were 94 earthquakes displayed on my map
(c)
the
magnitude
of the
largest
event
-
The largest event had a magnitude of 6.0
(d)
the
depth range
of the earthquakes
-
The depth range of the earthquakes is 9.8 km to 10 km.
(a) Name the type of plate boundary shown in your figure.
-
Cascadia Plate Boundary/Convergent Plate Boundary
(b) how many
earthquakes are displayed on your map
-
84 earthquakes are displayed on my map
(c)
the
magnitude
of the
largest
event
-
The largest event had a magnitude of 4.8
(d)
the
depth range
of the earthquakes
-
The depth ranges from -1.7 km to 32.4 km
(a) Name the type of plate boundary shown in your figure.
