ROCK ⇒ In(PGA) = 0.2418 + 1.414M – 2.552 ln(R + 1.7818e0.554M) + 0.00607H
SOIL → In(PGA) = −0.6687 +1.438M - 2.329 ln(R + 1.097e0.617M) + 0.00648H
where PGA is the maximum acceleration in g, M is the magnitude, R is the epicentral distance in km and H is the depth where the earthquake occurred in km.
2. Determine the PGA values for rock and soil, using the point I attenuation laws, for the following scenery: scenery 1: M = 5; H=20km; R = 10, 50, 100 and 200 km (perform the calculation for the 4 distances)
scenery 2: M = 6; H = 20 km; R = 10, 50, 100 and 200 km (perform the calculation for the 4 distances)
scenery 3 : M = 7, H = 20 km, R = 10, 50, 100 and 200 km (perform the calculation for the 4 distances)
3. Plot the values (use double logarithmic scale) and compare the results.
4. Send a report with the results obtained.
