Ndete Napu is a fumarole field in the center of Flores island, Indonesia. It is located along the Lowomelo river valley and contains mudpots and high-pressure water fountains. The field is listed as an active volcano based on its thermal activity. [1]
A caldera is a large cauldron-like hollow that forms shortly after the emptying of a magma chamber/reservoir in a volcanic eruption. When large volumes of magma are erupted over a short time, structural support for the rock above the magma chamber is lost. The ground surface then collapses downward into the emptied or partially emptied magma chamber, leaving a massive depression at the surface. Although sometimes described as a crater, the feature is actually a type of sinkhole, as it is formed through subsidence and collapse rather than an explosion or impact. Only seven caldera-forming collapses are known to have occurred since 1900, most recently at Bárðarbunga volcano, Iceland in 2014.
Krakatoa, or Krakatau, is a caldera in the Sunda Strait between the islands of Java and Sumatra in the Indonesian province of Lampung. The caldera is part of a volcanic island group comprising four islands: two of which, Lang and Verlaten, are remnants of a previous volcanic edifice destroyed in eruptions long before the famous 1883 eruption; another, Rakata, is the remnant of a much larger island destroyed in the 1883 eruption.
Rapeseed is a bright-yellow flowering member of the family Brassicaceae, cultivated mainly for its oil-rich seed, which naturally contains appreciable amounts of toxic erucic acid. Canola are a group of rapeseed cultivars which were bred to have very low levels of erucic acid and are especially prized for use for human and animal food. Rapeseed is the third-largest source of vegetable oil and second-largest source of protein meal in the world.
Mount Galunggung is an active stratovolcano in West Java, Indonesia, around 80 km (50 mi) southeast of the West Java provincial capital, Bandung. Mount Galunggung is part of the Sunda Arc extending through Sumatra, Java and Bali, which has resulted from the subduction of the Australian plate beneath the Eurasian plate. Galunggung had its first historical eruption in 1500 that produced pyroclastic flows and lahars that killed 4,011 people.
Mount Merapi, Gunung Merapi, is an active stratovolcano located on the border between Central Java and Special Region of Yogyakarta provinces, Indonesia. It is the most active volcano in Indonesia and has erupted regularly since 1548. It is located approximately 28 kilometres (17 mi) north of Yogyakarta city which has a population of 2.4 million, and thousands of people live on the flanks of the volcano, with villages as high as 1,700 metres (5,600 ft) above sea level.
Mount Agung is an active volcano in Bali, Indonesia, southeast of Mount Batur volcano, also in Bali. It is the highest point on Bali, and dominates the surrounding area, influencing the climate, especially rainfall patterns. From a distance, the mountain appears to be perfectly conical. From the peak of the mountain, it is possible to see the peak of Mount Rinjani on the nearby island of Lombok, to the east, although both mountains are frequently covered in clouds. Agung is a stratovolcano, with a large and deep crater. Its most recent eruptions occurred from 2017–2019.
A mud volcano or mud dome is a landform created by the eruption of mud or slurries, water and gases. Several geological processes may cause the formation of mud volcanoes. Mud volcanoes are not true igneous volcanoes as they do not produce lava and are not necessarily driven by magmatic activity. The Earth continuously exudes a mud-like substance, which may sometimes be referred to as a "mud volcano". Mud volcanoes may range in size from merely 1 or 2 meters high and 1 or 2 meters wide, to 700 meters high and 10 kilometers wide. Smaller mud exudations are sometimes referred to as mud-pots.
Kelud is an active stratovolcano located in East Java, Indonesia. Like many Indonesian volcanoes and others on the Pacific Ring of Fire, Kelud is known for large explosive eruptions throughout its history. More than 30 eruptions have occurred since 1000 AD. In 2007, an effusive explosion filled the crater with a lava dome. It last erupted on February 13, 2014, destroying the lava dome and ejecting boulders, stones and ashes up to West Java about 500 kilometers from Mount Kelud. The crater filled with water during the rainy season.
Anak Krakatoa is an island in a caldera in the Sunda Strait between the islands of Java and Sumatra in the Indonesian province of Lampung. On December 29, 1927, Anak Krakatoa emerged from the caldera formed in 1883 by the explosive volcanic eruption that destroyed the island of Krakatoa. There has been sporadic eruptive activity at the site since the late 20th century, culminating with a large underwater collapse of the volcano which caused a deadly tsunami in December 2018, followed by subsequent activity in 2019 and an eruption in April 2020. Due to its young age, the island is one of several in the area which are of considerable interest to volcanologists, and the subject of extensive study.
Karangetang is a volcano on the north side of Siau Island off the coast of Sulawesi, Indonesia. The island is inhabited by 22,000 people. It is one of the most active volcanoes in Indonesia having erupted 41 times since 1675. A pyroclastic flow in 1997 killed three people.
The Sidoarjo mud flow or Lapindo mud is the result of an erupting mud volcano in the subdistrict of Porong, Sidoarjo in East Java, Indonesia that has been in eruption since May 2006. It is the biggest mud volcano in the world; responsibility for it was credited to the blowout of a natural gas well drilled by PT Lapindo Brantas, although some scientists and company officials contend it was caused by a distant earthquake.
Kamojang, popularly known as Kawah Kamojang or, is a geothermal field and tourist spot in West Java, Indonesia. The crater is located in sub-district (kecamatan) Ibun in the Bandung Regency, approximately 45 km to the southeast of Bandung through the towns of Majalaya and Ibun. The crater can also be reached from the opposite direction through the town of Garut, in Garut Regency.
Mount Ungaran is a deeply eroded stratovolcano, located in the south of Semarang, Indonesia. There are no historical records about the mountain's activities. Two active fumarole fields are found on the southern flanks.
Mount Tondano in the province of North Sulawesi, Sulawesi, Indonesia, has a 20 × 30 km wide caldera which was formed in the Late Miocene or Early Pliocene formed by a massive eruption. Post caldera activity includes Pyroclastic cones, obsidian flows and geothermal areas in the caldera area. The Lake Tondano lies in the east side of the caldera.
The greater mouse-deer, greater Malay chevrotain, or napu is a species of even-toed ungulate in the family Tragulidae found in Sumatra, Borneo, and smaller Malaysian and Indonesian islands, and in southern Myanmar, southern Thailand, and peninsular Malaysia. Its natural habitat is subtropical or tropical, moist, lowland forest.
Napu is an Austronesian language spoken in the North Lore district of Central Sulawesi, Indonesia. Together with Bada and Behoa, it belongs to the Badaic subgroup.
Bada (Badaʼ) is an Austronesian language spoken in the South Lore district of Central Sulawesi, Indonesia. Together with Napu and Behoa, it belongs to the Badaic subgroup.
Behoa is an Austronesian language spoken in the North Lore district of Central Sulawesi, Indonesia. Together with Napu and Bada, it belongs to the Badaic subgroup. Based on lexical similarity, Behoa occupies an immediate position within Badaic between Napu and Bada; nevertheless it is geographically, politically and culturally distinct.
