Living with the danger 🌋
Millions of people live near volcanoes and fault lines even though they could be hit by an eruption or an earthquake. They stay for many reasons, from fertile soil to jobs and family. Where the risk cannot be removed, it can be reduced. This module looks at why people stay and the four ways they lower the risk.
Words for managing risk 🔑
Learn these four ways of reducing the risk from a tectonic hazard.
Stay or reduce the risk? 🆚
There are reasons people stay, and ways they make it safer.
Grade 9 thinking 💡
Explain how a strategy saves lives, not just its name. Earthquake-resistant buildings stay standing so fewer people are crushed, and evacuation planning gets people away in time. Remember that volcanoes can often be predicted from warning signs, but earthquakes still cannot be predicted reliably.
Match the strategy 🔗
- monitoring
