How much warning time do you have for a tsunami?
five minutes
5.7 How quickly are tsunami messages issued?

In regions of high seismic network density, the warning centers can issue messages within five minutes.
Is Oregon safe from tsunami?

What will happen to Oregon when the big one hits?
Oregon has the potential for a 9.0+ magnitude earthquake caused by the Cascadia Subduction Zone and a resulting tsunami of up to 100 feet in height that will impact the coastal area.
Whats the safest place in a tsunami?

Still others will die later as a result of habitat destruction or water-quality issues caused by the tsunami’s passage.
Can a boat survive a tsunami?
Boats are safer from tsunami damage while in the deep ocean ( > 100 m) rather than moored in a harbor. But, do not risk your life and attempt to motor your boat into deep water if it is too close to wave arrival time. Anticipate slowdowns caused by traffic gridlock and hundreds of other boaters heading out to sea.
