Many population centers are located near active fault zones and/or active plate boundaries, such as the San Andreas Fault. Millions of people in these population centers have suffered personal and economic losses due to volcanic and earthquake activity.
Defining Problems Associated With Earthquakes:
- There is evidence to support the idea that tectonic activity contributed to the demise (fall) of ancient civilizations. Based on the locations of current population centers, scientists have developed models that show that populations today may be just as vulnerable to the after effects of powerful earthquakes.
- When exposed to sudden forces produced by seismic waves buildings and bridges can fail completely and collapse, crushing the people in and around them.
- Modern population centers tend to be more densely packed with large numbers of tall buildings. The complex infrastructure of modern cities also poses a danger in case of a major earthquake.
Efforts to Minimize the Effects of Earthquakes:
- Over the past few decades, architects and engineers have developed a number of innovative technologies to ensure houses, and skyscrapers bend instead of break. Making these building more pliable, less brittle, and better able to move with the earthquake waves has made it possible for inhabitants to survive extremely destructive earthquakes.

Topic Tips
- Many people live on or near plate boundaries where catastrophic events such as earthquakes are inevitable. Engineers can design clever ways to help protect people.
