Indonesia is an archipelagic country located in Southeast Asia and Oceania, lying between the Indian Ocean and the Pacific Ocean. It is located in a strategic location astride or along major sea lanes connecting East Asia, South Asia and Oceania. Indonesia is the largest archipelago in the world. Indonesia's various regional cultures have been shaped—although not specifically determined—by centuries of complex interactions with its physical environment.
The Bromo, or Mount Bromo is an active somma volcano, a Hindu pilgrimage site, 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 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. Adjacent to the volcano is a 6-by-8.5-kilometre caldera, which is filled partially by the crater lake known as Segara Anak or Anak Laut, due to the color of its water, as blue as the sea (laut). This lake is approximately 2,000 metres (6,600 ft) above sea level and estimated to be about 200 metres (660 ft) deep; the caldera also contains hot springs. The lake and mountain are sacred to the Sasak people and Hindus, and are the site of religious rituals. UNESCO made Mount Rinjani Caldera a part of the Global Geoparks Network in April 2018.
Anak Krakatau is a volcanic island in Indonesia. On 29 December 1927, Anak Krakatau first 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 in a large underwater collapse of the volcano, which caused a deadly tsunami in December 2018. There has been subsequent activity since. Owing to its young age the island is one of several in the area that are of interest to, and the subject of extensive study by volcanologists.
Karangetang, also known as Api Siau is a volcano on the north side of Siau Island off the coast of Sulawesi, Indonesia. The island covers 160 km2, and had 46,459 inhabitants in mid 2023. It is one of the most active volcanoes in Indonesia, having erupted 41 times since 1675. A pyroclastic flow in 1997 killed three people.

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 Dempo is the highest stratovolcano in South Sumatra province that rises above Pasumah Plain near Pagar Alam and adjacent with Bengkulu Province. Seven craters are found around the summit. A 400-metre (1,300 ft) wide lake is found at the north-west end of the crater complex.
Bromo Tengger Semeru National Park is a national park located in East Java, Indonesia, to the east of Malang and Lumajang, to the south of Pasuruan and Probolinggo, and to the southeast of Surabaya, the capital of East Java. It is the only conservation area in Indonesia that has a sand sea, the Tengger Sand Sea, across which is the caldera of an ancient volcano (Tengger) from which four new volcanic cones have emerged. This unique feature covers a total area of 5,250 hectares at an altitude of about 2,100 meters (6,900 ft). The massif also contains the highest mountain in Java, Mount Semeru, four lakes and 50 rivers. It is named after the Tengger tribe. The explosion of the volcano that created the caldera, happened ca. 45.000 years ago, in an event similar to the Krakatau eruption.
Mount Talinis is a complex volcano in the Philippine province of Negros Oriental.

The Nevado de Toluca National Park is located southwest of the city of Toluca, Mexico State. It was decreed a park in 1936, primarily to protect the Nevado de Toluca volcano, which forms nearly the park's entire surface and is the fourth highest peak in Mexico. It is 45 km from Toluca and 135 from Mexico City. The park was established with the aim of conservation, but the park is under increasing pressure from the growth of the Toluca metropolitan area as well as from illegal logging done by local communities who need the income. The volcano has been long extinct and has a large crater in which are two shallow lakes. The crater and lakes are popular with visitors from Mexico State and Mexico City, especially when there is snow. There are a number of archeological sites in the park, including the lakes themselves, which contain numerous offerings of copal and other items that were deposited during the pre-Hispanic period. The park offers activities such as hiking, mountain biking and horseback riding as well as limited skiing facilities. Due to its altitude, the summit of the Nevado is significantly colder than the surrounding area.
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.
