Rescue operations are underway Monday on Indonesia's Lombok island for hikers and guides who were stranded on Mount Rinjani following a powerful earthquake Sunday that caused landslides on the mountain.

The Rinjani National Park chief says at least 500 people, many of them foreigners, remain "trapped" on the mountain which is the site of Indonesia's second highest volcano. 

The death toll from the earthquake has risen to 16, with 162 people injured.
