A tsunami has hit coastal areas of Russia's Kuril Islands and Japan's large northern island of Hokkaido after an 8.7-magnitude earthquake early Wednesday. Tsunami warning sirens blared Tuesday in Honolulu and people were told to move to higher ground. The Japan Meteorological Agency said a first tsunami wave of about 30 centimeters reached Nemuro on the eastern coast of Hokkaido.

The first tsunami wave hit the coastal area of Severo-Kurilsk, the main settlement on Russia's Kuril Islands in the Pacific, according to the local governor Valery Limarenko. He said residents were safe and staying on high ground until the threat of a repeat wave was gone. The Pacific Tsunami Warning Center said waves of 1 to 3 meters above tide level were possible along some coastal areas of Hawaii, Chile, Japan and the Solomon Islands. Waves of more than 3 meters were possible along some coastal areas of Russia and Ecuador.
