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. http://earthquake.usgs.gov/earthquakes/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 Earthquake #2 Location: 19.973 S: 168.398 E Location: 4.276 S: 102.086 W Magnitude: M 6.0 Magnitude: M 5.1 Time: 2023- 10-28 23:32:08 Time:2023-10-28 19:56:06 Depth: 79.9 km Depth: 60 km Earthquake #3 Earthquake #4 Location: 22.594 S: 67.148 W Location:17.309 N: 67.852 W Magnitude: M 4.4 Magnitude: M 3.1 Time: 2023-10-29 12:37:38 Time: 2023-10-29 13:11:55 Depth: 226.6 km Depth: 99.6 km Earthquake #5 Earthquake #6: Location: 9.208 N: 125.601 E Location: 72.924 N: 5.374 E Magnitude: M 4.6 Magnitude: M 4.1 Time: 2023-10-28 20:48:29 Time: 2023-10-29 04:56:58 Depth: 10.0 km Depth: 10.0 km Earthquake #7 Earthquake #8 Location: 69.712 N: 142.391 W Location:43.941 N: 28.384 W Magnitude: M 2.6 Magnitude: M 5.1 Time: 2023-10-29 07:12:38 Time: 2023-10-29 08:57:41 Depth: 6.1 km Depth: 10.0 km Earthquake #9 Earthquake #10 Location: 11.222 S: 29.804 E Location: 30.670 S: 178.165 W Magnitude: M 4.6 Magnitude: M 5.0 Time: 2023-10-28 20:35:24 Time: 2023-10-29 07:28:17 Depth: 10.0 km Depth: 35.0 km EARTHQUAKE THAT YOU ARE PLOTTING. (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.
