The magnitude-6.3 earthquake was centered 28 kilometers (17 miles) northeast of the Alor island chain in East Nusatenggara province, according to Indonesia's Meteorology and Geophysics Agency.
The US Geological Survey, which also put the magnitude at 6.3, said the quake had a depth of 14 kilometers (9 miles).
"The earthquake shook everything for about 11 seconds, causing people to run from their houses in panic," said Marthen Daud Ndauman, a government official on Alor, the island closest to the quake's epicenter.
The Meteorology and Geophysics Agency said the quake did not have the potential to trigger a tsunami.
Indonesia, the world's largest archipelago, is prone to seismic upheaval due to its location on the Pacific "Ring of Fire," an arc of volcanoes and fault lines encircling the Pacific Basin.
