Loloru is a pyroclastic shield volcano located in the southern region of Bougainville Island, within the Autonomous Region of Bougainville of northeastern Papua New Guinea.
The volcano's summit consists of two nested calderas, with an andesitic lava dome.
Lake Loloru is a crescent-shaped volcanic crater lake covering 0.9 km2 (0.35 sq mi) within the volcano caldera. It is a sacred place of South Bougainvillians, who traditionally believe the souls of their dead go here upon death.
Papua New Guinea is a country in Oceania that comprises the eastern half of the island of New Guinea and its offshore islands in Melanesia. Officially the Independent State of Papua New Guinea, it shares its only land border with Indonesia to the west and it is directly adjacent to Australia to the south and the Solomon Islands to the east. Its capital, located along its southeastern coast, is Port Moresby. The country is the world's third largest island country, with an area of 462,840 km2 (178,700 sq mi).
Bougainville, officially the Autonomous Region of Bougainville, is an autonomous region in Papua New Guinea. The largest island is Bougainville Island, while the region also includes Buka Island and a number of outlying islands and atolls. The current capital is Buka, situated on Buka Island.
Bougainville Island is the main island of the Autonomous Region of Bougainville, which is part of Papua New Guinea. It was previously the main landmass in the German Empire-associated North Solomons. Its land area is 9,300 km2 (3,600 sq mi). The population of the whole province, including nearby islets such as the Carterets, is approximately 300,000. The highest point is Mount Balbi, on the main island, at 2,715 m (8,907 ft). The much smaller Buka Island, c. 500 km2 (190 sq mi), lies to the north, across the 400–500 m (1,300–1,600 ft) wide Buka Strait. Even though the strait is narrow, there is no bridge across it, but there is a regular ferry service between the key settlements on either side. The main airport in the north is in the town of Buka.
Rabaul is a township in the East New Britain province of Papua New Guinea, on the island of New Britain. It lies about 600 kilometres to the east of the island of New Guinea. Rabaul was the provincial capital and most important settlement in the province until it was destroyed in 1994 by falling ash from a volcanic eruption in its harbor. During the eruption, ash was sent thousands of metres into the air, and the subsequent rain of ash caused 80% of the buildings in Rabaul to collapse. After the eruption the capital was moved to Kokopo, about 20 kilometres (12 mi) away. Rabaul is continually threatened by volcanic activity, because it is on the edge of the Rabaul caldera, a flooded caldera of a large pyroclastic shield.
For administrative purposes, Papua New Guinea is divided into administrative divisions called provinces. There are 22 provincial-level divisions, which include 20 provinces, the Autonomous Region of Bougainville, and the National Capital District of Port Moresby.

A complex volcano, also called a compound volcano or a volcanic complex, is a mixed landform consisting of related volcanic centers and their associated lava flows and pyroclastic rock. They may form due to changes in eruptive habit or in the location of the principal vent area on a particular volcano. Stratovolcanoes can also form a large caldera that gets filled in by a lava dome, or else multiple small cinder cones, lava domes and craters may develop on the caldera's rim.
Long Island is a populated volcanic island in Madang Province, Papua New Guinea. It is located north of the island of New Guinea, separated from it by the Vitiaz Strait. The island's interior contains a 360m deep freshwater volcanic crater lake and within that lake exists an even smaller island known as Motmot island. During the late 17th or early 18th century virtually all of the biota on the island was destroyed and has subsequently provided scientists a unique opportunity to study recolonization efforts by plants, animals, and humans. The vast majority of the buildings on the island are constructed using vernacular architecture.
Buka is a town located on the southern coast of Buka Island, in the Autonomous Region of Bougainville, in eastern Papua New Guinea. It is administered under Buka Rural LLG. It is the capital of the North Bougainville District and the interim capital of the Autonomous Region of Bougainville. It contains Our Lady of the Assumption Cathedral.
Mount Balbi is a Holocene stratovolcano located in the northern portion of the island of Bougainville, Papua New Guinea. A gentle prominence at 05°54′09″S154°59′28″E is the highest point of the island. There are five volcanic craters east of the summit, one of which contains a crater lake. The summit is composed of coalesced cones and lava domes which host a large solfatera field. There are numerous fumaroles near the craters, though Balbi has not erupted in historic time.
Bagana is an active volcanic cone located in the centre of the island of Bougainville, Papua New Guinea, the largest island of the Solomon group. It is the most active volcano in the country, occupying a remote portion of central Bougainville Island. It is one of Melanesia's youngest and most active volcanoes.
Billy Mitchell is a pyroclastic shield in the central part of the island of Bougainville, just north-east of the Bagana Volcano in Papua New Guinea. It is a small pyroclastic shield truncated by a 2 km wide caldera filled by a crater lake. It is named after Billy Mitchell, a 20th-century United States Army general who is regarded as the father of the United States Air Force.
Tore is a volcano located in the northern part of the island of Bougainville, Papua New Guinea. Violent Pleistocene eruptions produced two ignimbrite fans stretching west to the coast, and a 6 km by 9 km caldera. A post-caldera lava cone on the caldera's southern rim is the source of lava flows. Well-preserved features suggests a recent date for this cone and a nearby ash cone.

In volcanology, a pyroclastic shield or ignimbrite shield is an uncommon type of shield volcano. Unlike most shield volcanoes, pyroclastic shields are formed mostly of pyroclastic and highly explosive eruptions rather than relatively fluid basaltic lava issuing from vents or fissures on the surface of the volcano. They typically display low-angle flank slopes and often have a central caldera caused by large eruptions. Lava is commonly extruded after explosive activity has ended. The paucity of associated Plinian fall deposits indicates that pyroclastic shields are characterized by low Plinian columns.
Buin is a town on Bougainville Island, and the capital of the South Bougainville District, in the Autonomous Region of Bougainville, in eastern Papua New Guinea. The island is in the northern Solomon Islands Archipelago of the Melanesia region, in the South Pacific Ocean.
A lava cone is a type of volcano composed primarily of viscous lava flows. The volcanic cone can contain a convex profile due to the flank flows of viscous lava.
The Bougainville conflict, also known as the Bougainville Civil War, was a multi-layered armed conflict fought from 1988 to 1998 in the North Solomons Province of Papua New Guinea (PNG) between PNG and the secessionist forces of the Bougainville Revolutionary Army (BRA), and between the BRA and other armed groups on Bougainville. The conflict was described by Bougainvillean President John Momis as the largest conflict in Oceania since the end of World War II in 1945, with an estimated 15,000–20,000 Bougainvilleans dead, although lower estimates place the toll at around 1,000–2,000.
