An 8.8 magnitude earthquake off Russia triggers tsunami warnings in the Pacific, as the first waves reach Hawaii.

The earthquake, with its epicenter 126 kilometers from the Russian coastal city of Petropavlovsk-Kamchatsky and a depth of 19.3 kilometers, measured 8.8 on the Richter scale and prompted authorities to issue tsunami warnings. Waves have already been recorded in the Kuril Islands, but no casualties have been confirmed.

Japan has ordered evacuations of its northern coast, where waves of up to three meters are expected. According to the country's Meteorological Agency, a tsunami of up to 60 centimeters was detected as the waves moved south along the Pacific coast, from Hokkaido to Tokyo Bay. About two million residents have received evacuation notices in more than 220 municipalities along the Pacific coast.

Parts of China's east coast, along the provinces of Shanghai and Zhejiang, are also on alert, as are coastal areas of Canada, the Philippines and Mexico.

Waves ranging from 30 centimeters to 1.5 meters are expected in parts of Alaska, Oregon, Washington and California and according to authorities, the impacts of the tsunami could be felt over the next few hours or even days.

The first waves have already arrived in Honolulu, Hawaii, and residents have been advised to move to higher ground.
