“There is no tsunami threat,” it said on Twitter.
The quake struck northern Sumatra at 8.39am local time (9.39am in Malaysia), the US Geological Survey said, but there were no immediate reports of casualties or structural damage.

In a statement, the Kuala Lumpur fire and rescue department said its operations centre received several emergency calls from buildings across the city, with the meteorological department confirming with them that the Sumatra earthquake was the source.
None of the calls the fire and rescue department received reported any structural damage to the buildings or injuries to the occupants.
Among the calls were from Menara Maybank on Jalan Tun Perak, Menara AmBank on Jalan Yap Kwan Seng, Menara Glomac on Jalan Damansara, and Axiata Tower on Jalan Stesen Sentral.
Calls were also received from buildings along Jalan Sultan Ismail, Jalan Ampang, Jalan Raja Chulan and Jalan Pahang.
Several buildings were evacuated, with Pertama Complex in Kuala Lumpur and Menara Axis in Section 52, Petaling Jaya among them.
“Even I felt the tremors at the police headquarters,” Petaling Jaya police chief Mohamad Fakhrudin Abdul Hamid told FMT.
“The meteorological department confirmed with us that it was because of the Sumatra earthquake.”
He added that police had yet to receive any reports about accidents or damage to buildings.
Reports about the tremors quickly started trending on Twitter, where a user with the handle @1Obefiend reported seeing a building swaying in Kuala Lumpur. However, he did not provide details.
Meanwhile, a video uploaded by @prakashchris was captioned “Earthquake felt at Putrajaya”. It showed a group of people leaving what looked like a government building.
Another Twitter user, @deputt, said tremors were felt in Subang, Puchong, Section 13 in Petaling Jaya and Bangsar South.
