A magnitude 5.5 earthquake occurs 10 km from a city. Using the formula I = aM + b log(r) + c (a, b, c constants provided as 1, 0.5, 2), calculate the estimated intensity.
💡 Hint: Calculate log values first then substitute back.
Discuss how an earthquake of magnitude 7.0 could lead to high intensity values in a poorly constructed area despite its distance.
💡 Hint: Consider structural factors and soil types.
