Jakarta  - An undersea earthquake measuring 6.2 on the Richter scale struck Tuesday off the northern tip of Sulawesi island, but there were no immediate reports of injury and damage, meteorologists said.

The quake at a depth of 18 kilometres near the Talaud islands between Sulawesi and the southern Philippines occurred at 6:38 pm Jakarta time (1138 GMT), the Indonesian Meteorology and Geophysics Agency said.

It said the quake did not trigger a tsunami, and there were no immediate reports of injury or structural damage.

A powerful 7.4-magnitude quake jolted the same area on February 12, injuring dozens of people and damaging hundreds of buildings.(dpa)
