After a volcano erupted at one of the country's most popular hiking destinations, the Indonesian government sent rescuers to help the people trapped there, the Indonesian authorities have evacuated nearly more than 400 tourists and are tracking down several hundred others at Mount Barujari, on Lombok island.
The volcano, which sits within the Mount Rinjani caldera, erupted Tuesday afternoon, delaying flights from airports on the islands of Lombok and Bali. The ash column reached a height of about 2,000 meters (6,562 feet).
A disaster mitigation agency spokesman, Sutopo Purwo Nugroho, said nearly 400 foreign and local tourists were registered since Sunday to climb the mountain.
"We are still searching for about 389 other tourists, mostly foreign tourists, to find out their condition and to evacuate them immediately," the Guardian quoted Nugroho as saying.
There have been no reports of injuries from the eruption.
The eruption interrupted flights for several hours at Ngurah Rai International Airport in Bali and Lombok International Airport.
Farms and trees around the volcano were coated in a thin layer of gray ash, but nearby towns and villages weren't in danger, Mr. Nugroho said.
Indonesia sits on the Pacific Ring of Fire, an area of high seismic and volcanic activity which is home to more than 400 volcanoes, including at least 129 that are still active and 65 qualified as dangerous.
