A BRAZILIAN woman has been found dead in Indonesia after she was trapped in an active volcano for four days, her family has revealed.

Juliana Marins, 26, fell over 1,600 feet from a trail along the crater rim of Mount Rinjani while hiking with a small group.

Juliana, a publicist and dancer, from Niterói, based near Rio de Janeiro, had been documenting her backpacking trip through Southeast Asia on Instagram.

She was spotted inside the crater by passing tourists, who heard her screams for help.

Drone footage showed her sitting in a volcano pit, appearing out of energy.

She is said to have rolled nearly 1,000ft down the slope before coming to a stop in a rocky ravine on the Indonesian island of Lombok.

Indonesian authorities deployed three helicopters to try and rescue Juliana, according to West Nusa Tenggara governor Lalu Muhamad Iqbal.

Iqbal told reporters: “One helicopter from the Indonesian Armed Forces and national search and rescue agency (Basarnas) is expected to arrive at Zainuddin Abdul Madjid International Airport (BIZAM) around 2pm local time today.”
