What do engineers do?
Engineers use science math and CREATIVITY to solve problems
Solving problems that face people on the coast
Tsunami Inundation Large amount of water floods into a land area usually above sea level – this is measured in feet (or meters) above sea level
Cascadia Subduction Zone 30 min 1 in 7 chance in the next 50 years
45 – 60 min to evacuate the beach Tsunami Evacuation Area Tsunami Evacuation Area
How Can Engineers Help?
