GO 150 Earth Science Environmental Hazards Plate Tectonics LAB Performance Assessment Go to the following USGS site to see current worldwide earthquake (Magnitude 2.5+) data. BEFORE you
begin, enlarge the map to a worldwide view. Epicenters should be spread out over entire map.

21 Points Gavyn Elkamil
Enlarge the map to a worldwide view. Type a list of ten of the larger earthquakes given on the site. The ten earthquakes chosen
should be WORLDWIDE and not limited to the United States. Be sure to number each
earthquake. Use the following as an example. Give location, magnitude, time, and depth. Note:
If you click on the earthquake on the map, on the side the latitude and longitude will be given
along with magnitude, depth etc. After you have listed the ten chosen earthquakes, plot them
on the map that follows. Place a red dot onto the map provided where the earthquake
occurred. After plotting the epicenters and analyzing the earthquake data, type your answers to
the three questions below the map. Do not research the cause of the earthquakes. Your answers
should come from your own analysis of the location of the epicenter and the type of boundary
listed on the map provided. Upload your completed document as a performance assessment of
your
ability to relate real life earthquake data to the movement of the Earth’s crustal plates at
crustal plate boundaries. Again, do not research answers on the internet. This is your
analysis. SAVE THIS DOCUMENT AS A PDF BEFORE SUBMITTING THE LAB DOCUMENT TO THE DROP BOX
TO PRESERVE THE PLACEMENT OF THE EPICENTERS ON THE MAP. NO QUESTIONS WILL BE GRADED WITHOUT THE EPICENTERS PLOTTED ON THE PROVIDED MAP. Earthquake #1:
Location
(Ex. Latitude and Longitude)
Magnitude
(Ex. M 2.5)
Time (Ex. 2023-04-02 21:00:14 UTC)
Depth
(Ex. 4.3 km)
NOTE: Although the map on the USGS website is interactive, the map below is not. You may select a red dot at the top of the map and then drag it to the location of the earthquake you are plotting. MAKE SURE THE NUMBER ON THE CIRCLE CORRESPONDS WITH THE CORRECT Earthquake #1

(EX. Earthquake #1 will be plotted on the map with dot #1).
Answers to the questions will NOT be graded without the earthquakes plotted on the map below
and included with your assignment.
Analyze: 1.
How many of your earthquakes appear to be located on or very near a crustal plate boundary? (NOTE: Do not answer this question with “about” or “almost”. You answer will be a number.)
Give the number of total earthquakes on or near the boundary and then list the numbers of the earthquakes you classified as on or near a boundary. 8 of the 10 are close to a crustal plate boundary. 1, 2, 3, 4, 5, 6, 8, 10
2.
Based on the map key or legend, what types
of boundaries had earthquakes plotted on them? Not only list the types of boundaries, include the number of each earthquake located on or very near each boundary type. (NOTE: This answer should match your response to the first question.
A “hot spot” is not a boundary type and should not be listed here.) 1, 2, 3, 4, 5, 10 are on convergent plate boundaries while 6 and 8 are on divergent plate boundaries.
3.
Find the largest magnitude earthquake
plotted on your map that occurred on a plate boundary
. Give the number of the largest of your ten earthquakes. Also give the magnitude and location
of the largest magnitude earthquake plotted on the map. Analyze earthquake based on the map provided. Do not include information researched, this is your personal analysis in your words. Analysis should include the cause of the earthquake in relationship to Plate Tectonics based on the plate boundary type
. This can be determined by looking at the

motion of the two
main plates involved. Be sure to include the names of the two main plates involved
. Identify the type of plate boundary
and the type of movement typical of plates at this type of boundary
that was likely to have caused this earthquake. If subduction is occurring and indicated by the symbol on the map, identify the subducting and overriding plate and why the plate was subducted. Your answer should come from your personal analysis of the map and your epicenter. Do not include names of plates not on this map. Earthquake #1 has the largest magnitude at 6.0 and location at 19.973 S: 168.398 E. The convergent plate boundary due to the overriding plate and the subducting plate coming together.
