Tsunami Risk 

John Creek township is located very close to the edge of Lake Hāwea, making it vulnerable to lake-generated waves in the event of a significant earthquake. If a large landslide were to occur, it could create waves that would impact homes along the foreshore. Residents of John Creek should respond by moving to higher ground, following similar procedures as those for coastal evacuation. Open areas away from hazards are the safest places to be during an earthquake. 

It’s important to note that Lake Hāwea township is situated at a higher elevation than John Creek, so this particular risk is unique to the John Creek area.
