Drone films breathtaking descent into Ijen volcano, Indonesia

Spanish filmmaker Andres Aguilera Morillas piloted a drone into the crater of  2 743 m (9 000 ft) Ijen volcano-- a mountain filled with acidic water and sulphuric smoke-- situated in Java, Indonesia. The drone footage captured the spectacular view, showing the inner side of the volcano while descending through dense clouds.

The drone gilded between the picturesque cracks and crevice of the volcano before it reaches the crater lake filled with blue acidic water. Columns of smoke were captured as the footage ends.

Ijen volcano has the world's biggest acidic volcanic crater lake and is popular for its light blue-turquoise color. It has a pH level of 0.5.

Kawah Ijen, a volcano located in the Ijen volcano complex, released toxic gases on March 21, 2018, injuring 24 people. The incident started around 19:00 local time and peaked around 21:00.

Authorities said 30 people were exposed to gas and 24 of them sent to local hospitals.

One of the locals said that residents living in 3 hamlets close to the crater (Margahayu Hamlet, Watu Capil and Dusun Curah Macan), have been evacuated to Puskemas Kecamaten Ijen.

Geological summary

The Ijen volcano complex at the eastern end of Java consists of a group of small stratovolcanoes constructed within the large 20-km-wide (12.4 miles) Ijen (Kendeng) caldera.

The north caldera wall forms a prominent arcuate ridge, but elsewhere the caldera rim is buried by post-caldera volcanoes, including Gunung Merapi, which forms the high point of the complex. Immediately west of the Gunung Merapi stratovolcano is the historically active Kawah Ijen crater, which contains a nearly 1-km-wide (0.62 miles), turquoise-colored, acid lake.

Picturesque Kawah Ijen is the world's largest highly acidic lake and is the site of a labor-intensive sulfur mining operation in which sulfur-laden baskets are hand-carried from the crater floor. Many other post-caldera cones and craters are located within the caldera or along its rim.

The largest concentration of cones forms an E-W zone across the southern side of the caldera. Coffee plantations cover much of the caldera floor, and tourists are drawn to its waterfalls, hot springs, and volcanic scenery.
