In the early, early hours of Tuesday morning phones lit up along the Washington coast alerting to the possibility of a tsunami. A 7.9 magnitude earthquake had just hit in the Gulf of Alaska.

This exposes a lot of questions about how ready we are for the big waves. The Seattle Times' science reporter Sandi Doughtonexplains what was learned after this latest tsunami warning.
