TOKYO (Reuters) ��" Tsunami waves of up to 1.5 metres (5 feet) hit far-flung Pacific regions from the Russian far east and Japan to New Zealand's remote Chatham Islands on Sunday after a massive earthquake struck Chile, killing more than 300 people. Authorities ordered hundreds of thousands of residents in Japan, New Zealand, the Philippines and Russia's Kamchatka to evacuate after Saturday's Chile quake, one of the world's most powerful in a century, but there were no immediate reports of damage. In Japan, a 1.45 meter tsunami hit the fishing port of Otsuchi on the north Pacific coast, Kyodo news agency said. Smaller waves hit a swathe of the country from the small island of Minamitori 1,950 km (1,200 miles) south of Tokyo to Hokkaido island in the north, the Japan Meteorological Agency said. Japanese officials have ordered or advised some 540,000 households along the country's Pacific coast to evacuate and said later waves could be much bigger. "The full-fledged tsunami waves are starting to arrive," University of Tokyo professor Yoshinobu Tsuji told NHK public TV.
