One of the world's strongest earthquakes struck Russia's Far East early Wednesday, an 8.8-magnitude temblor that set off a tsunami in the northern Pacific region and prompted warnings for Alaska, Hawaii and south toward New Zealand.
Tsunami warning sirens blared Tuesday in Honolulu and people moved to higher ground.
The Japan Meteorological Agency said a first tsunami wave of about 30 centimeters (about 1 foot) reached Nemuro on the eastern coast of Hokkaido.
