The World’s Most Dangerous and Beautiful Adventure Places-4.Mount Sinabung (Indonesia)

Mount Sinabung (Indonesia)

Mount Sinabung is an active stratovolcano located in the Karo Regency of North Sumatra, Indonesia. It is one of the most active volcanoes in Indonesia, and has erupted frequently since 2010, after being dormant for nearly 400 years. It is also one of the most dangerous and spectacular volcanoes in the world, as it produces massive pyroclastic flows, ash plumes, and lava domes, creating a stunning and terrifying scenery.

Formation

Mount Sinabung is part of the Sunda Arc, a volcanic arc that is formed by the subduction of the Indo-Australian Plate under the Eurasian Plate. The Sunda Arc extends from the Andaman Islands to the Banda Arc, and includes many volcanoes in Indonesia. Mount Sinabung is a composite volcano, composed of layers of lava and ash, and has four craters, but only one is active.

Eruptions

Mount Sinabung has a long history of eruptions, dating back to the Pleistocene and Holocene epochs. However, the historical records of its eruptions are scarce and unreliable, as the volcano was considered extinct for a long time. The last confirmed eruption before 2010 was in 1600, and the volcano remained quiet until 2010, when it suddenly awakened and started to erupt.

2010 Eruption

On August 29, 2010, Mount Sinabung erupted for the first time in 400 years, after several days of rumbling. The eruption produced a 1.5 km high ash column, and lava overflowed from the crater. The eruption triggered the evacuation of about 18,000 people from the nearby villages, and the highest alert level was issued by the Indonesian government. The volcano erupted again on August 30, sending a 2 km high ash plume into the air, and disrupting the international flights.

2013 Eruption

On September 15, 2013, Mount Sinabung erupted again, after three years of dormancy. The eruption generated large pyroclastic flows, which are fast-moving mixtures of hot gas and rock, that can reach temperatures of up to 700°C and speeds of up to 700 km/h. The pyroclastic flows destroyed several villages and crops, and forced more than 3,700 people to flee. No casualties were reported. The eruption marked the beginning of a prolonged phase of activity, which lasted until 2018.

2014 Eruption

On February 1, 2014, Mount Sinabung erupted violently, producing the largest and deadliest pyroclastic flows of its recent history. The pyroclastic flows reached up to 4.5 km from the crater, and killed 16 people, including four students, who were visiting the volcano. More than 20,000 people were displaced by the eruption, and many of them suffered from respiratory problems and psychological trauma.

2016 Eruption

On May 21, 2016, Mount Sinabung erupted again, sending a 3 km high ash column into the sky, and ash and smoke over the local villages. The eruption killed seven people, who were farming near the volcano, and injured several others. The eruption also damaged the infrastructure and the environment, and disrupted the tourism and the agriculture.

2018 Eruption

On February 19, 2018, Mount Sinabung erupted once more, producing a 5 km high ash plume, and a 3-3.5 km long pyroclastic flow. The eruption did not cause any casualties, but it affected the air traffic, as the Australian Volcanic Ash Advisory Centre issued the highest level of red alert for the flights. The eruption also covered the nearby villages with thick ash, and affected the lives of thousands of people. Some people chose to stay and protect their homes, while others left to seek refuge in nearby cities. The authorities distributed masks and urged the people to avoid outdoor activities, as the ash could cause respiratory problems.

2019 Eruption

On May 7, 2019, Mount Sinabung erupted again, producing a 2 km high ash column, and ash and smoke over the local villages. The authorities advised the people living near the river streams of the volcano to be alert for possible lava flows, and said that the eruption could affect the air travel, although they did not issue any formal recommendation for the planes to avoid the area. The eruption was the largest one since 2018, and the volcano remained at the third level of alert.

2020 Eruption

On August 10, 2020, Mount Sinabung erupted for the first time in 2020, and continued to erupt on August 18 and 23. The eruptions produced ash plumes of up to 5 km high, and pyroclastic flows of up to 4.5 km long. The eruptions also triggered the evacuation of more than 2,000 people from the danger zone, and the closure of some schools and airports.

2021 Eruption

On March 2, 2021, Mount Sinabung erupted once more, producing a 5 km high ash plume, and a 2 km long pyroclastic flow. The eruption did not cause any casualties, but it affected the visibility and the air quality, and disrupted the flights. The eruption was the largest one since 2019, and the volcano remained at the third level of alert.

Conclusion

Mount Sinabung is one of the most active and dangerous volcanoes in Indonesia, and in the world. It has erupted frequently and violently since 2010, after being dormant for nearly 400 years. It has produced massive pyroclastic flows, ash plumes, and lava domes, creating a stunning and terrifying scenery. It has also caused many deaths, injuries, displacements, and damages, and affected the lives and the livelihoods of thousands of people. It is a volcano that deserves respect and caution, and a volcano that fascinates and challenges the scientists and the explorers.
