TANJUNG, Indonesia (AP) — The Indonesian island of Lombok was shaken by a third big earthquake in little more than a week Thursday as the official death toll from the most powerful of the quakes topped 300.

The strong aftershock, measured at magnitude 5.9 by the U.S. Geological Survey, caused panic, damage to buildings, landslides and injuries. It was centered in the northwest of the island and didn’t have the potential to cause a tsunami, Indonesia’s geological agency said.
