SEASIDE, Ore. — Sirens have begun sounding in some communities on the Oregon coast to urge people to seek higher ground as a tsunami crossed the Pacific Ocean following a massive earthquake in Japan.

A siren was blasted in Rockaway Beach at about 5 a.m. Friday and they were sounding in other low-lying areas as well.

At least one hotel in Seaside has been evacuated as a precaution. Guests were being moved to higher floors at another.

Information indicated a wave of more than 6 feet could reach Brookings in southern Oregon, while a wave of about 4 1/2 feet was predicted for northern Oregon's Clatsop spit. The waves are expected between 7 a.m. and 8 a.m.
