A powerful 8.7-magnitude earthquake in Russia triggered a tsunami that has hit northern Japan, prompting evacuation efforts for nearly 2 million people from Tokyo and nearby coastal areas. The first tsunami wave struck Hokkaido with a height of about 30 centimeters, but warnings indicate waves could reach up to 3 meters. Transport systems, including Sendai Airport and ferry services, have been disrupted. Authorities are monitoring for aftershocks and assessing damage in both Japan and Russia’s Kamchatka region.
