(CNN) A trio of intense earthquakes shook several islands in the South Pacific and Indonesia on Sunday, including two on the already battered island of Lombok.

The most recent major quake was a 6.9 magnitude tremor centered just 4 kilometers south of Belanting, on the Indonesian island of Lombok.

That island is still trying to recover from the devastating effects of an August 5 earthquake that killed more than 430 people.

The earthquake came just hours after two other tremors rattled Southeast Asia and the South Pacific.
