Several whales were found beached on Japan's coast after a massive 8.8-magnitude quake off Russia triggered Pacific-wide tsunami alerts. Waves up to 4 metres hit parts of Russia and Japan, prompting evacuations, including at the Fukushima nuclear plant. The quake, among the top 10 ever recorded, caused flooding in Russia's Severo-Kurilsk and several aftershocks followed. Tsunami warnings remain in effect across multiple Pacific nations.
