1 ERSC 1P92 (EXTREME EARTH) – ASSIGNMENT 2 (enter answers in Quizzes tool) ERSC 1P92 – EXTREME EARTH – ASSIGNMENT 2 ASSIGNMENT DUE BY FRIDAY, NOVEMBER 10, 2023 Preamble: In this assignment we will broadly cover topics relevant to modules three and four of the ERSC 1P92 course. Please answer all questions before entering your answers in the Quizzes tool in Brightspace. You will have only one opportunity to submit your answers in the Quizzes tool. Points per question are given in brackets (x). Part A of the assignment will be related to recent Earthquake events that have occurred and plate tectonic boundaries. Part B of the assignment will involve readings related to Earthquake events in the past as well as in Canada. Work through the assignment, then, when you have it complete, go to the Quizzes tab in Brightspace to enter your answers and submit the assignment. Rules and guidelines for assignments are in your course syllabus . As always with online tools, save your work frequently while entering answers. Assignment Questions 1-58 REMINDER! Please answer all questions before entering your answers under the Quizzes section in Brightspace. PART A A list of actual earthquakes that have occurred worldwide from July 1-28, 2023 are provided for you on a separate data sheet posted in the Brightspace Assignment tool. You can find the location of the earthquakes by clicking on the location site, or if you’d like to get an ‘overall’ picture of the earthquake event locations you can plot the locations yourself on the World Plate boundary map provided. Please note! You do not need to plot the earthquake locations as part of this Assignment! The World plate boundary map is ONLY provided as an assistance if NEEDED! Hints for plotting : In order to PLOT an earthquake event, you will need to use the Latitude and Longitude information provided. Lines of Latitude appear horizontal (“ side to side” ) and are measured as degrees north (N) or south (S) of the equator (the equator is 0°). Longitude lines run vertically (“up and down”) and measure the degrees East (E) or West (W) of the Prime Meridian (0° runs through Greenwich, England). A sample plot of a theoretical Shallow depth earthquake at 60 deg W and 45 deg N has been plotted for you on the map. The Earthquake events that have been provided on the separate data sheet (from July 1-28, 2023 ), can be assigned a ‘’depth code’’ according to the DEPTH
