Java (island) in the context of "Dutch East Indies"

Dewi Sri or Shridevi (Javanese: ꦢꦺꦮꦶꦱꦿꦶ, Balinese: ᬤᬾᬯᬶᬲ᭄ᬭᬶ, Dewi Sri, Sundanese: ᮑᮄ ᮕᮧᮠᮎᮤ ᮞᮀᮠᮡᮀ ᮃᮞᮢᮤ, Nyai Pohaci Sanghyang Asri) is the Javanese, Sundanese, and Balinese Hindu Goddess of rice and fertility, still widely worshiped on the islands of Java, Bali and Lombok, Indonesia. She is often associated or equated with the Hindu goddess Lakshmi, the shakti (consort) of Vishnu.

East Java (Indonesian: Jawa Timur, Javanese: ꦙꦮꦶꦮꦺꦠꦤ꧀, romanized: Jawi Wétan, Madurese: Jhâbâ Tèmor) is a province of Indonesia located in the easternmost third of Java island. It has a land border only with the province of Central Java to the west; the Java Sea and the Indian Ocean border its northern and southern coasts, respectively, while the narrow Bali Strait to the east separates Java from Bali by around 2.29 kilometres (1.42 mi). Located in eastern Java, the province also includes the island of Madura (which is connected to Java by the longest bridge in Indonesia, the Suramadu Bridge), as well as the Kangean islands and other smaller island groups located further east (in the northern Bali Sea) and the Masalembu archipelago to the north. Its capital is Surabaya, the second largest city in Indonesia, a major industrial center and also a major business center. Banyuwangi is the largest regency in East Java and the largest on the island of Java.

The province covers a land area of 48,036.84 square kilometres (18,547.13 sq mi), and according to the 2010 Census, there were 37,476,757 people residing there, making it Indonesia's second-most-populous province; the 2020 Census showed an increase to 40,665,696 people, while the official estimate for mid 2024 was 41,914,499 (comprising 20,848,660 males and 20,965,880 females). Almost a quarter of the population lives inside the Greater Surabaya metropolitan area. East Java is inhabited by many different ethnic groups, such as the Javanese, Madurese and Chinese. Most of the people in East Java adhere to Islam, forming around 94% of the total population. Other religions are also practiced, such as Christianity, Buddhism and Confucianism which are mostly practised by Tionghoa people and immigrants from Eastern Indonesia and North Sumatra, and also Hinduism which are practised by the Tenggerese people in the Bromo Tengger Semeru National Park and the Balinese people inhabiting the easternmost part of the province bordering Bali as well as the dominant minority Indian Indonesians in Surabaya city.

The Balinese (Balinese: ᬳᬦᬓ᭄‌ᬩᬮᬶ, romanized: Anak Bali (in the ketah register), ᬯᭀᬂᬩᬮᬶ, Wong Bali (in the madia register), ᬓ᭄ᬭᬫᬩᬮᬶ, Krama Bali (in the singgih register); Indonesian: Orang Bali) are an Austronesian ethnic group native to the Indonesian island of Bali and the surrounding islands. The Balinese population of 4.2 million (1.7% of Indonesia's population) live mostly on the island of Bali, making up 85% of the island's population. The Balinese are distinctive amongst the ethnic groups of Indonesia for their adherence to Balinese Hinduism rather than Abrahamic religions such as Islam or Christianity.

There are also significant populations on the island of Lombok and in the easternmost regions of Java (e.g. the regency of Banyuwangi), most of them are descendants of Balinese since the kingdoms era who once controlled the region. Some Balinese can also be found in Balinese migrant areas such as Lampung and Sulawesi regions, mainly due to the migration following the eruption of Mount Agung in 1963 as well as the transmigration program enacted by the Indonesian government.

Ujung Kulon National Park (Indonesian: Taman Nasional Ujung Kulon) is a national park at the westernmost tip of Java, located in Sumur District of Pandeglang Regency, part of Banten province in Indonesia. It once included the volcanic island group of Krakatoa in Lampung province, although current maps has suggested the Krakatoa island group as its own protected area, the Pulau Anak Krakatau Marine Nature Reserve.

The area has been declared a UNESCO World Heritage Site for "containing the largest remaining area of lowland rainforests in Java", and also for possessing the most threatened species of rhino, the Javan rhino. It was designated before its formation as a national park.

Sangiran is an archaeological excavation site in Java in Indonesia. According to a UNESCO report (1995) "Sangiran is recognized by scientists to be one of the most important sites in the world for studying fossil man, ranking alongside Zhoukoudian (China), Willandra Lakes (Australia), Olduvai Gorge (Tanzania), and Sterkfontein (South Africa), and more fruitful in finds than any of these."

The area comprises about 56 km (7 km x 8 km). It is located in Central Java, about 15 kilometers north of Surakarta in the Solo River valley. Administratively, Sangiran area is divided between 2 regencies: Sragen (districts of Gemolong, Kalijambe, and Plupuh) and Karanganyar (district of Gondangrejo). An important feature of the site is the geology of the area. Originally a dome was created millions of years ago through tectonic uplifts. The dome was then eroded exposing beds within the dome which are rich in archeological records.

Wallacea /wɒˈleɪsiə/ is a biogeographical designation for a group of mainly Indonesian islands separated by deep-water straits from the Asian and Australian continental shelves. Wallacea includes Sulawesi, the largest island in the group, as well as Lombok, Sumbawa, Flores, Sumba, and Timor. The islands of Wallacea lie between the Sunda Shelf (the Malay Peninsula, Sumatra, Borneo, and Java) to the west, and the Sahul Shelf, including Australia, New Guinea, and Maluku islands to the south and east. The total land area of Wallacea is 347,000 km (134,000 sq mi).

A phreatic eruption, also called a phreatic explosion, ultravulcanian eruption or steam-blast eruption, occurs when magma heats ground water or surface water. The extreme temperature of the magma (anywhere from 500 to 1,170 °C (930 to 2,100 °F)) causes near-instantaneous evaporation of water to steam, resulting in an explosion of steam, water, ash, rock, and volcanic bombs. At Mount St. Helens in Washington state, hundreds of steam explosions preceded the 1980 Plinian eruption of the volcano. A less intense geothermal event may result in a mud volcano.

Phreatic eruptions typically include steam and rock fragments; the inclusion of liquid lava is unusual. The temperature of the fragments can range from cold to incandescent. If molten magma is included, volcanologists classify the event as a phreatomagmatic eruption. These eruptions occasionally create broad, low-relief craters called maars. Phreatic explosions can be accompanied by carbon dioxide or hydrogen sulfide gas-emissions. Carbon dioxide can asphyxiate at sufficient concentration; hydrogen sulfide acts as a broad-spectrum poison. A 1979 phreatic eruption on the island of Java killed 140 people, most of whom were overcome by poisonous gases.

The Sultanate of Mataram (/məˈtɑːrəm/) was the last major independent Javanese kingdom on the island of Java before it was colonised by the Dutch. It was the dominant political force radiating from the interior of Central Java from the late 16th century until the beginning of the 18th century.

Mataram reached its peak of power during the reign of Sultan Agung Anyokrokusumo (r. 1613–1645), and began to decline after his death in 1645. By the mid-18th century, Mataram lost both power and territory to the Dutch East India Company (Dutch: Vereenigde Oost-Indische Compagnie; VOC). It had become a vassal state of the company by 1749.
