Powerful quakes hit off coast of Indonesia's Sumatra Island
One at magnitude 6.7 Tuesday and one at 7.0 Monday hit the same area

A strong earthquake struck off the coast of Indonesia's Sumatra Island early Tuesday, the U.S. Geological Survey's Web site reported.
Two strong earthquakes -- one Monday and one Tuesday -- hit about 100 miles south-southwest of Padang.
The 6.7-magnitude quake is the ninth registering above 5.0 to strike the sparsely populated region since early Sunday. No damage or deaths have been reported from the series of quakes.
Tuesday's quake struck shortly after 1 a.m. (1 p.m. ET) about 164 km (102 miles) south-southwest of Padang on Sumatra Island in western Indonesia, according to the USGS.
The Pacific Tsunami Warning Center did not issue a tsunami warning after determining that a "destructive widespread tsunami threat does not exist."
Ten hours earlier, a 7.0-magnitude "major" quake struck the same area, triggering a tsunami watch that was later canceled.
Sunday night, a 6.5-magnitude quake hit about 155 km (96 miles) south-southwest of Padang.
Last Wednesday, a quake registering 7.5 in magnitude shook the region, killing three people
