Gamalama is a near-conical stratovolcano that comprises the entire Ternate island in Indonesia. The island lies off the western shore of Halmahera island in the north of the Maluku Islands. For centuries, Ternate was a center of Portuguese and Dutch forts for spice trade, which have accounted for thorough reports of Gamalama's volcanic activities.
An eruption in 1775 caused the deaths of approximately 1300 people. [3]
On December 4, 2011 Mount Gamalama erupted, ejecting material up to 2,000 meters into the air. Thousands of residents in nearby Ternate City fled due to ash and dust particles raining down on the town. [4] Finally on December 27 some 4 people died and dozens injured from debris falls (lahar) after a month of activity. [5]
More eruptions occurred in September 2012. [6]
An eruption on December 18, 2014, deposited five centimeters of ash on the runway of Babullah Airport in Ternate, closing the airport. [7]
Mount Tambora, or Tomboro, is an active stratovolcano in West Nusa Tenggara, Indonesia. Located on Sumbawa in the Lesser Sunda Islands, it was formed by the active subduction zones beneath it. Before 1815, its elevation reached more than 4,300 metres high, making it one of the tallest peaks in the Indonesian archipelago.
The Bromo, or Mount Bromo is an active somma volcano and part of the Tengger mountains, in East Java, Indonesia. At 2,329 meters (7,641 ft) it is not the highest peak of the massif, but is the most active and famous. The area is one of the most visited tourist destinations in East Java, and the volcano is included in the Bromo Tengger Semeru National Park. The name Bromo comes from the Javanese pronunciation of Brahma, the Hindu god of creation. At the mouth of the crater, there is an idol of Ganesha, the Hindu god of wisdom which is being worshipped by the Javanese Hindus. Mount Bromo is located in the middle of a plain called "Sea of Sand", a nature reserve that has been protected since 1919.
Mount Pinatubo is an active stratovolcano in the Zambales Mountains, located on the tripoint boundary of the Philippine provinces of Zambales, Tarlac and Pampanga, all in Central Luzon on the northern island of Luzon. Its eruptive history was unknown to most before the pre-eruption volcanic activity of early 1991. Pinatubo was heavily eroded and obscured from view by dense forests which supported a population of several thousand indigenous Aetas.
Mount Merapi, is an active stratovolcano located on the border between the province of Central Java and the Special Region of Yogyakarta, Indonesia. It is the most active volcano in Indonesia and has erupted regularly since 1548. It is located approximately 28 km (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 m (5,577 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.
Mount Rinjani is an active volcano in Indonesia on the island of Lombok. Administratively the mountain is in the Regency of North Lombok, West Nusa Tenggara. It rises to 3,726 metres (12,224 ft), making it the second highest volcano in Indonesia. It is also the highest point in the Indonesian province of West Nusa Tenggara.
The Kelud is an mountain stratovolcano located in Kediri, 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 13 February 2014, destroying the lava dome and ejecting boulders, stones and ashes up to West Java about 500 kilometres (310 mi) from Mount Kelud. The crater filled with water during the rainy season.
Ulawun is a basaltic and andesitic stratovolcano in West New Britain Province, on the island of New Britain in Papua New Guinea.
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 Semeru, or Mount Semeru is an active volcano located in East Java, Indonesia. It is located in a subduction zone, where the Indo-Australian plate subducts under the Eurasia plate. It is the highest mountain on the island of Java. The name "Semeru" is derived from Meru, the central world mountain in Hinduism, or Sumeru, the abode of gods. This stratovolcano is Mahameru, meaning "The Great Mountain" in Sanskrit. It is one of the more popular hiking destinations in Indonesia.
The Marapi, or Mount Marapi, is a complex volcano in West Sumatra, Indonesia, and is the most active volcano in Sumatra. Like that of its quasi-homonym on Java, its name means "Mountain of Fire". Its elevation is 2,885 metres (9,465.2 ft). Several cities and towns are situated around the mountain including Bukittinggi, Padang Panjang, and Batusangkar. The volcano is also popular among hikers.
Soputan is a stratovolcano in Indonesia. It is on the northern arm of Sulawesi island and rises to an elevation of 1,785 m (5,853 ft). The geologically young and mostly unvegetated cone is primarily constructed of andesite and basalt rock. It sits on the southern rim of the Tondano caldera, which formed in the Quaternary period. The volcano is one of Sulawesi's most active, with 39 confirmed eruptions in the last 600 years. Eruptive activity at Soputan typically consists of pyroclastic flows, lava flows, lava domes and Strombolian-style explosions.
Mount Sinabung is a Pleistocene-to-Holocene stratovolcano of andesite and dacite in the Karo plateau of Karo Regency, North Sumatra, Indonesia, 40 kilometres (25 mi) from the Lake Toba supervolcano. Many old lava flows are on its flanks and the last known eruption, before recent times, occurred 1200 years before present, between 740 - 880 CE. Solfataric activities were last observed at the summit in 1912; recent documented events include an eruption in the early hours of 29 August 2010 and eruptions in September and November 2013, January, February and October 2014. The volcano has recently claimed the life of at least 23 people in a number of events since 2014. Between 2013 and 2014, the alert for a major event was increased with no significant activity. On 2 June 2015, the alert was again increased, and on 26 June 2015, at least 10,000 people were evacuated, fearing a major eruption. The long eruption of Mount Sinabung is similar to that of Mount Unzen in Japan, which erupted for five years after lying dormant for 400 years. A major eruption began on 10 August 2020.
Mount Lokon, also known as Gunung Lokon, together with Mount Empung, is a twin volcano in the Tomohon, Minahasa Regency, North Sulawesi, Indonesia, roughly 10 km (6 mi) south of Manado. Both rise above the Tondano plain and are among active volcanoes of Sulawesi. Mount Lokon has a flat and craterless top. Its active crater is located on its foot, named "Tompaluan" crater.
Mount Gamkonora is a stratovolcano on Halmahera island, Indonesia. With an elevation of 1,560 metres (5,118 ft), it is the highest peak on the island. It has produced an elongated series of craters along the north–south rift.
In late October 2010, Mount Merapi in border of Central Java and Special Region of Yogyakarta, Indonesia began an increasingly violent series of eruptions that continued into November. Seismic activity around the volcano increased from mid-September onwards, culminating in repeated outbursts of lava and volcanic ash. Large eruption columns formed, causing numerous pyroclastic flows down the heavily populated slopes of the volcano. The 2010 eruption of Merapi was the volcano's largest since 1872.
Mount Agung, a volcano on the island of Bali in Indonesia, erupted five times in late November 2017, causing thousands to evacuate, disrupting air travel and causing environmental damage. As of 27 November 2017, the alert level was at its highest and evacuation orders were in place.
