Homework Questions
• Would you live in an area at risk for tsunamis? If so, where?
• What level of risk from tsunamis is acceptable to you? (How would you know if the risk was assessed accurately?)
• What should be done by people and communities in tsunami-prone areas to prepare for the hazard and prevent catastrophe?

The Coast
• Over 50% of the Earth’s people live within 50 miles of a coast!
• Typically susceptible to flooding• Impact of flooding– property damage– loss of life– saltwater intrusion

Tsunami Response
• Identify areas at risk• Warning system– earthquake monitoring– tsunami detection
• Warning signs– earthquake– trough arrival
