Sesson 2: Engineering Mitigation

Key Idea.

Section 1

Engineers Design Safer Structures

Key Idea

Natural hazards like hurricanes can damage homes and towns with powerful wind and rain. While people cannot stop a storm from happening, they can take action to make buildings and communities safer.

People can think like engineers to solve this problem. They create special plans to build stronger structures or improve older ones. This smart planning is a type of engineering mitigation. The goal is to reduce, or lessen, the damage a storm might bring.

Section 2

People Reduce a Storm's Damage

Key Idea

Big storms like hurricanes are a powerful part of nature. People cannot stop a natural hazard from happening. The strong winds and heavy rain will still come, no matter what people do.

Instead of stopping the storm, people can take smart steps to be safer. They can change buildings and towns to better handle the storm's power. These actions help reduce the damage to homes and keep communities protected.

Section 3

Engineers Design Stronger Buildings

Key Idea

Big storms like hurricanes bring very strong winds and lots of rain. These powerful forces can push on buildings and sometimes knock them down.

People cannot stop a hurricane from happening. Instead, engineers find ways to make buildings safer. They change the designs of houses and other structures to protect them.
