A 6.4-magnitude earthquake has struck off the province of Aceh, in the north of Indonesia's Sumatra region, on 7 December. However, no tsunami alert has been issued.

The quake hit 10km north of Reuleuet at about 5am (11pm GMT) local time, the US Geological Survey said. In its initial assessment, the USGS said that there was a low likelihood of casualties and damage.

In June 2016, a 6.5-magnitude earthquake struck the west of Sumatra, resulting in damage to several building and injuring eight people.

In 2004, a quake-triggered tsunami killed more than 170,000 people in Indonesia and tens of thousands more in other countries around the Indian Ocean.
