EOSC 114 – Final Review Notes Get A’s or die trying. Jason Kim Unit 1: A Fragile System At least 3 earthquake recording stations are required to find the location of the earthquake epicenter. A single recording station can only calculate distance, but not direction; to cover all possibilities, a complete circle is drawn around that station. If only two earthquake recording stations are used, the circles will overlap at two points. Data from a third recording station will eliminate one of these points. Explain what density is & how it relates to stratification. Density = mass/volume; how much mass fits into a space. Unit: kg/m3 3 Stratification = less-dense materials float on top of denser materials This is found in the…show more content…
1. Hazards can be predicted through scientific analysis Scientific method used Predicted by Identifying location, finding probability, looking for precursor events, forecasting, warning 2. Risk analysis is an important element in understand the effects of hazards Risk = probability * consequences 3. Linkages among different hazards exist 4. Damage from natural disasters is increasing 5. 6. Damage and loss of life can be minimized Explain (with examples) how energy conservation applies to natural disasters. Energy is conserved when it changes form. Most sources of energy are diffuse: weak, but cover a wide area Disasters generally have a concentration of energy into a small area Describe relationships between force, pressure, stress, strain, energy, and power. Power: work/consuming energy per second = measured in watts Pressure: force per unit surface area applied perpendicular to a surface Stress: force per unit area applied parallel to a surface Stress tends to strain deform objects Describe population n growth and explain why it is important for natural disasters. Population growth was
