Chapter 4 Plate Tectonics and Earthquake

1.In 100 to 200 words: Describe common hazards that follow major earthquakes in cities.

 

2. In 200 to 400 words: What factors combined to cause the resonance in México City that was so deadly in the 1985 earthquake? How far was the city from the epicenter? Two days after the earthquake, the city was shaken by a magnitude 7.5 earthquake. Would you consider this a main-shock and an aftershock or twin earthquakes?
