HOMEWORK TWO GEOSCI 250 FALL 2005 DUE WEDNESDAY 10/26

 

OBJECTIVE 1: MAP TABULAR DATA FOR GLOBAL-HISTORICAL EARTHQUAKES

OBJECTIVE 2: RETAIN BASIC CONCEPTS OF EARTHQUAKE TECTONICS (and landslides).

 

PLACE ALL SHORT ANSWERS ON A SEPARATE SHEET OF PAPER

 

Please note that you have ‘artistic license’ on graphics and maps, but the information must be complete an accurate. The VERY BRIEF answers to questions are ‘open ended’, and YOUR INTERPRETATIONS are called for here.

 

Diagram 1: Plate Tectonics AND EARTHQUAKES

 

·      Using the DIAGRAM as reference (on page 62, Figure 3.16 in your textbook) AND the corresponding slide Five (figure 2.19) in the ‘Chapter & Lecture Review Presentations’ Earthquake Review Part 1, fill in the information that completes this diagram

·      INCLUDE an example of each tectonic feature-one NOT shown in the reference slide.

·      Add the depth profile for each tectonic feature from Earthquake Review Part 1 (shallow-moderate; or shallow-moderate-deep). Does the Subduction-Collision zone always correspond to high frequency, fatalities? (Maps from the previous homework 1) Where does it NOT correspond? (Name a tectonic or global region). Why?

 

 

 

Diagram 2: This is the next page that has six separate FAULT diagrams.

 

 

These diagrams can be found in your in your textbook (pages 84-87) and the ‘Chapter & Lecture Review Presentations’, Earthquake Review Part 1 Slide 22 & Slide 23.

 

·      Fill in the diagram in a complete a way as possible, including text, arrows. Add the textual material from the review slides.

·      Name an example of a global location for each type of fault show next to the diagram (Remember your plates map in your textbook on page 52 and slide 9 in the Earthquake Review Part 1, AND that transform faults are also strike-slip faults, and that strike-slip faults can often occur adjacent to Subduction-collision zones).  

·      Looking at the plates map (again), which type of fault (Dip or Strike) appears TO YOU to have the greatest disaster potential? Why?

 

 

Table 1 & Map 1: Giving earthquake data a geographic face.

 

Using the table, and the map on the back and USING A LEGEND, MAP the following variables by continent. The continent limits-boundaries are found on the MAP in ‘Chapter & Lecture Review Presentations’, Earthquake Review Part 1, Slide 3 (delineate these in some fashion on your map).

 

 

·      Shade the AREA of the continent by NUMBER OF AFFECTED (NOT TOTAL), from light-low to dark-high.

·      Place SOLID circles of THREE graduated sizes corresponding to the continents’ NUMBER OF KILLED – largest-Rank 1, smallest-Rank 3.

·      Place HOLLOW circles of THREE graduated sizes corresponding to the continents’ NUMBER OF INJURED – largest-Rank 1, smallest-Rank 3.

·      What is the relationship of the above variables with POP 2004 and POPULATION DENSITY (2004)

·      Label the continents with the NUMBER OF EVENTS in rank order 1-5. With what variables do frequencies correspond, and in what way?

·      Label the continents.

 

Map 2: Earthquake Vulnerability

 

Using the GLOBAL SEISMIC HAZARD MAP found in ‘Chapter & Lecture Review Presentations’, Earthquake Review Part 1, Slide 7 AS A GUIDE, shape in some fashion the highest risk areas for earthquakes.

 

·      How does this risk area correspond to the geographies found on your MAP 1 (above)?

·      Label the map with potential earthquake COMPOSITE EFFECTS at each high-risk area, and ADD OTHER natural hazards that may impact the risk areas. Think about the location and geomorphology of the risk area.

 

 

 

Diagram 3: Types of Landslides (CHAPTER 9 in your textbook), we will review the material Monday.

 

·      Reproduce the diagram (Earthquake/Landslide Review Part 2 Slide 26, and on page 245, figure 9.16 in your textbook).

·      Which types do you think may accompany earthquakes? What other earth systems realms or cycles are needed to facilitate landslides? Does this variety of factors, some coincident, make landslides a major hazard relative to others?

·      How did landslides effect the situation in the recent Pakistan quake?

 

Diagram 4: Design your own Diagram!

 

·      On a blank sheet of paper, create your own graphic interpretation of the behavior of BODY seismic WAVES and SURFACE seismic waves. Include a diagram of the motion(s) of the earth’s surface created by each wave type.

·      The Pakistan Earthquake was 7.6 Magnitude on the Richter scale. Using the tables, charts in your textbook, and in the Earthquake Review Part 2 (to be posted) and LINKS; what would be the Mercalli Intensity of this quake? Justify your answer with examples.
