The biggest tragedy during a tsunami is the loss of life, so what the residents of Maui could do, with a number of hours of warning to to make sure that all the people, but also pets and life stock were moved to a higher ground.
Additionally, they could probably have taken their small valuables (wallets and laptops) and they could have evacuated in an orderly fashion since there was a lot of time left
TSUNAMI EVACUATION - Sirens will sound. Turn on radio. Those who are in tsunami evacuation zones must begin evacuation when the evacuation advisory/order is issued by civil defense.
I hope my answer has come to your help. God bless and have a nice day ahead!
