Question 1
Consider a scenario where an earthquake has a primary rupture located 5 km from a building. If the recorded horizontal PGA is 0.6g towards the building and 0.4g perpendicular to it, calculate the combined Vector PGA.
💡 Hint: You’ll need to apply the Pythagorean theorem here to combine the horizontal components.
Question 2
Discuss how neglecting forward directivity can pose risks in urban planning, especially in seismic zones.
💡 Hint: Consider what impacts may arise from assumptions made about shaking intensity.
