Pad *86%- Exercise 3 Earthquake Hazards James S. Reichard Georgia Southern University Kewanis Rucker Student Name Section_ In this lab you will the loss of life and property damage. Background Reading and Needed Supplies examine various earthquake hazards and some of the techniques that can help minimize Prior to doing this exercise you should read Chapter 4 in the textbook. With respect to supplies, you will need a calculator, ruler, and colored pencils. Part I- Earthquakes and Plate Tectonics Each year, the vibrational (seismic) waves from earthquakes cause buildings to fail somewhere in the world, resulting in the death of large numbers of people. In addition to buildings, earthquakes cause considerable damage to human infrastructure, such as utility lines and transportation systems. Seismic waves also can trigger highly destructive tsunamis and landslides. Although humans cannot prevent earthquakes, we can use science and engineering to help minimize the hazards. In this exercise we will explore some of the earthquake hazards and ways we can reduce the loss of life and property damage. 1) The map in Figure 3.1 shows the location of earthquake epicenters that occurred over a 35- year period. Note how the epicenters clearly define the edge of Earth's tectonic plates. a) Using a red colored pencil, place a set of arrows at the plate boundaries listed below so as to indicate whether the boundary is dominated by compressional, tensional, or shearing forces (i.e., indicate whether the boundaries are convergent, divergent, or transform. mid-ocean ridge in the Atlantic western coast of South America western coast of North America Aleutian Islands of Alaska Japan Islands of Indonesia b) What is the name of the geologic process that takes place along the plate boundary running through the Atlantic basin? map? which is capable of bringing death and destruction to distant shorelines? c) What geologic process occurs along the convergent boundaries you identified on the d) What is the name of the earthquake hazard that can develop along convergent boundaries e) Explain why large magnitude earthquakes are relatively rare along divergent boundaries, but quite common along convergent boundaries.

Explanation / Answer

1

a) mid oceanic ridge in Atlantic - - - - - divergent plate boundary

Western coast of South America - - - - - - - - - convergent plate boundary

Western coast of North America - - - - - - - - - transform plate boundary

Aleutian islands of Alaska - - - - - - - - - - - - - - - convergent plate boundary

Japan - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - convergent plate boundary

Islands of Indonesia - - - - - - - - - - - - - - - - - - - - - convergent Plate boundary

b) it is sea spreading. The process in which two plates are move apart from each other because of some tectonic activity like volacanic eruption. for ex, mid oceanic ridges present in Atlantic Ocean.

c) when two plates collides, one get suducted beneath another. For ex, oceanic plate suducted beneath the continental plate.

d) convergent plate boundary means formation of subduction zones which causes the tsunami into the ocean which affects the shoreline and destruction.

e) As we know, divergent plate boundaries in which plates are moving away from each other. Convergent plate boundaries in which plates are moving each other.

Now, the tension and compression are the responsible factor for earthquake, which are rarely seen at divergent plate boundaries because at divergent plate boundaries, the magma from inside Come to the surface which does not affect the compression and tension to the rock. Ex. Mid oceanic ridge between America and Africa.

Whereas at the convergent plate boundaries, the two plates are colliding, one is suducting below other which made the compression and tension very high and hence earthquakes are common at convergent plate boundaries. Ex. Himalaya.
