This earthquake struck in the southern Mentawai Straits as well as adjacent parts of Bengkulu, Jambi and Sumatera Barat provinces province on Sumatra just to the north of a Mw=8.4 event that struck the same region the previous day. This earthquake was strongly felt in many parts of Sumatra. Damage was reported in Jambi province. However, it is unclear which of the three earthquakes were responsible for this damage. The Major General A. Thalib Hospital was damaged at Sugainpenuh while elsewhere in the Kerinci district, damage to buildings was reported from the districts of Keliling Danau, Danau Kerinci and Siulak. At Padang, patients were evacuated to makeshift tent in the open at the Dr. M. Jamil Hospital, Reksodiwiryo Hospital and Yos Sudarso Hospital in the city after buildings developed cracks.

Across the Malacca Straits, this earthquake was felt in Malaysia. At Penang it was felt in high-rise buildings at places such as Jalan Sultan Ahmed Shah and Downing Street while in the capital, Kuala Lumpur, it was felt at Jalan Ampang, Jalan Tun Abdul Razak and Lembah Pantai.
