JAKARTA, Jan. 14 (Xinhuanet) -- Two earthquakes measuring 5.2 and 6.7 on the Richter scale jolted Gunung Sitoli, a town in Indonesia's North Sumatra province, on Friday evening, Antara news agency reported on Saturday.

    The epicenter of the first quake is 1.61 north latitude and 96.65 east longitude, at the depth of 25 km in the sea, about 132 km southwest of Gunung Sitoli. The epicenter of the second quake is 0.79 north latitude and 97.12 east longitude, at the depth of 15 km in the sea, some 68 km southwest of the town, the North Sumatra Meteorology and Geophysics Agency said.

    There is still no report about damage caused by the quakes. Earthquakes have shaken Gunung Sitoli in the last several days, and the North Sumatra Meteorology and Geophysics Agency has continued to monitor the tremors.

    Meanwhile, an earthquake measuring 5.3 on the Richter scale shook the country's tsunami-devastated Banda Aceh and its environs on Friday night but there was no immediate report of casualty.

    The epicenter of the tremor, which occurred at 09:47 p.m., was located in the Indian Ocean, about 90 km southwest of Banda Aceh, at the depth of 30 km, the head of the local geophysics and meteorology agency, Syahman, said on Saturday.

    Since early this year the agency has recorded a total of 173 tremors but only three of them could be felt by people.

    Compared to previous years, the frequency of tremors tended to increase after a tsunami triggered by a 8.9 magnitude earthquake devastated parts of Aceh on Dec. 26, 2004.

    More than 150,000 people were killed and hundreds of thousands of others were made displaced in the tsunami. Enditem
