The epicenter of the quake which struck at 02.41 p.m. was in the sea 71 km southwest of the Aceh provincial capital at a depth of 33 km, spokesperson of the local meteorology, climatology and geophysics office Vina said.
The quake was not strong enough to trigger a tsunami.
"So far, there has been no report of casualties or material damage caused by the quake," she said.
Thursday`s quake was the latest in a series of quakes that rocked Indonesia`s western-most province.
The province was last hit by a strong quake measuring 6.0 on Richter scale on April 28, with the epicenter located 63 kilometers northwest of Meulaboh, West Aceh district, at a depth of 20 km.
Many people were panicked and rushed out of their houses or office buildings as they felt the strong tremors. However, there was no report of casualties or material damage.
Aceh bore the brunt of 8.9-magnitude undersea earthquake that unleashed a devastating tsunami on December 26, 2004, killing more than 200,000 people.(*)
