The tremor was recorded at 02:13 GMT, 68 kilometers (over 42 miles) north of Timor-Leste's capital of Dili, according to the USGS. The epicenter of the earthquake was located at a depth of 35 kilometers.
There are no reports about any victims or damage caused by the earthquake.
Timor-Leste is located in a seismically active region, known as the Ring of Fire, and often suffers from powerful earthquakes.
The island nation lies on a small Timor Plate that is moving to the north, toward the Banda Sea Plate, which increases the seismic activity in the region.
