EOSC114 Homework, Winter 2018: Volcanoes Student ID:___________________ Introduction: Today we start with an article of ~1000 words in the prestigious journal Nature Geoscience: http://www.nature.co... m.ezproxy.library.ubc.ca/ngeo/journal/v8/n4/full/ngeo2403.html. You may have to log into the library with your CWL, search for the title “Tying Down Eruption Risk”, then find the online version. After completing this assignment, you should be able to:  Describe the kinds of data or observations that help estimate recurrence intervals and ejecta volumes of past very large volcanic eruptions.  Justify the need for further research regarding very large volcanic eruptions by referring to difficulties associated with obtaining the kinds of data or observations described in the previous goal.  Examine and interpret data in a citation, without worrying about details of the entire cited article.  Obtain various details about any volcano on Earth, from a database of Earth’s volcanoes.  Characterize the relationships between claims made in this article, arguments that authors use to support these claims and evidence cited by authors supporting these arguments.  Characterize a scientific reading in terms of the type of article, the author’s intent and the type and reliability of his/her sources. Instructions 1. First skim all questions to find out what to expect, then read the article and complete the worksheet. 2. THEN, once you have completed the worksheet, go online to submit results within Connect. a. Time available for the online portion of this homework will be limited so you MUST do the reading and this worksheet BEFORE going online. b. The questions on Connect are automatically gradable versions of SOME of these worksheet questions, including some fill-blank, multiple choice, ordering/ranking and so on. c. Each student will get a different set of questions. 3. Note, there may be one or more questions about this assignment in future tests, quizzes or exams. 4. Regarding older versions of this exercise: This homework exercise AND its online data entry questions are only slightly similar to earlier versions of eosc114 homework. 5. This homework + miniproject should take between 2 and 5 hours and you have 2 weeks to do it. Step 1: Processes and predictions.  What is the location of Tambora, Sambawa Island, Indonesia? Enter the nearest whole number values with no decimals for latitude 8 degrees North, and longitude 118 degrees East. Use a negative number if latitude is South of the equator or if longitude is west of the meridian. This major eruption occurred in the year 1815 and resulted in roughly 60000 direct fatalities. How many years was this prior to the article’s publication 200 Finally, the article said this was probably [“similar to” / “smaller than” / “greater than”] the actual number of fatalities (choose one).  Which of these technical terms did you have trouble understanding even after looking them up? (You did look these up yourself first, right?) There are zero points for this question, however we will provide feedback, so please tell us honestly so we can help ensure the article was well-understood by everyone. a) magnitude b) caldera c) recurrence times d) ice cores e) source volcano f) dispersal pattern g) core sample area h) statistical models i) under-reporting j) ash k) pumice l) tephra m) pyroclastic flow n) remobilized o) stratospheric p) aerosols q) climate simulations r) geochronological analysis [Show More]
