Alaskans can get tsunami warnings in different ways, from cellphone alerts, to radio and TV messages, to actual sirens in many coastal communities.
But what if -- time after time -- they evacuate, only to find out later the resulting tsunami was only an inch or two high?
Experts like Humboldt State University Geologist Lori Dengler say, even so, they hope anyone in a tsunami zone knows their life could be in danger and they should be ready to evacuate.
Dengler says, first, people should also know that if they feel prolonged shaking in a coastal area, they should head to higher ground.
