Indeed, land is created on Java as a result of lava flows, ash deposits, and mud flows (lahars). Volcanoes are a major contributor to the immense fertility of Java, as natural erosion transports volcanic material as alluvium to the island's plains, forming thick layers of fertile sediment. The benefit is not just in the immediate vicinity of ...
During the night of 20 February 1979, the Sinila volcano of the Dieng Volcanic Complex erupted on the Indonesian island of Java in Central Java province. Over 175 people died, mainly due to gas poisoning in villages on the plateau near the Sinila crater. [7] [8] It was the fourth Sinila eruption since 1928, and the first one since 1951.
The measurement results indicated a rapidly increasing rate of growth of the lava dome in the buildup to the eruptive events of 25–26 October 2010. At the end of September 2010, the peak inflation rate of the lava dome at Mount Merapi was measured by EDM at an average growth rate of 6 mm (0.24 in).
An eruption of Mount Semeru, a volcano in East Java province of the Indonesian island of Java, began on 4 December 2021. The eruption began after heavy precipitation caused the collapse of the lava dome at the summit. Pyroclastic flows and lahars damaged at least 5,205 homes and several public buildings.
By 12 November, Mount Kelud began spewing lava into its crater lake. The lava dome, which had expanded to 250 metres (820 ft) long and 120 metres (390 ft) high, cracked open and lava began oozing into the surrounding water. Smoke rose more than two kilometres (1.2 mi; 6,600 ft) into the air, and ash dusted several villages around the volcano. [18]
The Ijen volcano complex is a group of composite volcanoes located on the border between Banyuwangi Regency and Bondowoso Regency of East Java, Indonesia. It is known for its blue fire, acidic crater lake, and labour-intensive sulfur mining.
Magma and lava appear to have originated from molten materials at a deeper part of the mantle as supported by a higher K 2 O/Na 2 O ratio in comparison to other parts of Sunda Arc. [ 3 ] [ 17 ] The most salient volcanoes in the back-arc region are Lasem, Muria , and Bawean in which their volcanic rocks show complex patterns in terms of chemical ...
Manjanggul (Korean: 만장굴) is a lava tube located in Gimnyeong-ri, Gujwaeup, Jeju City, South Korea.At up to 23 metres (75') wide, 30 metres (100') high and 8.928 km (5½ miles) long, it is the 12th-longest lava tube in the world and the second longest on Jeju Island, [1] although a significant portion of the cave is closed to visitors.
