A seismic wave traveling through three different rock layers with varying densities shows significant delay at the boundary. Calculate the expected delay if the first layer is 2 km thick at 5 km/s, the second layer is 3 km thick at 8 km/s, and the third layer is 1 km thick at 12 km/s. Discuss how this delay correlates with crustal heterogeneity.
💡 Hint: Break down the calculation layer by layer.
Analyze a scenario where an earthquake occurs in a region with significant crustal heterogeneity. Describe how this could impact the accuracy of epicenter location and the implications for disaster response.
💡 Hint: Consider what factors influence wave propagation and how that translates into real-world outcomes.
