A small tsunami has just hit the northern coast of Indonesia and minor waves have now begun hitting the Philippines, but without causing any damage, early reports said.

A tsunami of only 10 centimetres triggered by the earthquake in Japan was detected in the North Sulawesi and Maluku islands, an official from the Indonesian meteorology and geophysics agency said. We have just lifted the tsunami alert in Indonesia.''

Around 20 countries and numerous Pacific islands have been issued tsunami warning after a powerful 8.9-magnitude earthquake struck off Japan's northeastern coast Friday.

The US Geological Survey said the epicenter was about 250 miles from Tokyo at a depth of 20 miles. They earlier estimated the quake to be of 7.9 in magnitude but later revised it to 8.9 on Richter scale.

At least 32 people were killed and many injured in Japan after the massive quake spawned a tsunami as high as 10 metres.
