10 Most Active Volcanoes in Indonesia

Indonesia is listed as having 127 (there are 129) active volcanoes 4 of which have SIAGA status and 17 mountains have WASPADA status. This is because Indonesia is part of the Pacific Ring of Fire. The active volcano is located in an area of ​​approximately 5 million inhabitants. Of course this should be a concern so as not to fall victim to many when the mountains suddenly erupted and released the contents of his stomach.

Volcanoes are mountains that are formed due to erupted material deposited around the eruption center or mountains formed from magma eruptions. Volcanoes not only exist on the surface of the earth or land, but also in the depths of the sea. Volcano itself consists of three types based on activities that is active, rest, and not active or dead. Meanwhile, according to the shape, generally divided into four types: strato / cone, shield / shield, cinder cone, and caldera.

Volcanoes are found all over the world, whether on land with a human-occupied climate to a land situation with extreme conditions such as desert or eternal snow.

The famous location for the volcano is the area along the Pacific Ring of Fire that originated in New Zealand and ends in Nicaragua with Indonesia also in it. This area is also often referred to as the Pacific earthquake belt.

Indonesia is dominated by volcanoes formed by a subduction zone between the Eurasian plate and the Indo-Australian plate. Some volcanoes in Indonesia are renowned for their enormous eruptions and vukanic activity such as Krakatau erupted in 1883 with its global eruption, Lake Toba formed by the eruption of Supervulkan and suspected to be the cause of the volcanic winter for 6 years, Tambora erupting in 1815 and The impact that changed the world, and Merapi that has erupted more than 80 times so crowned as the Volcano of the Decade It since 1995

The Indonesian volcanic groups group volcanoes into three types based on historical eruptions / eruptions, namely:

Type A: was recorded to have experienced a magmatic eruption at least once after 1600.

Type B: after 1600 has not recorded yet another magmatic eruption but still shows symptoms of volcanic activity such as solfatara activity.

Type C: the history of eruptions is unknown in human records, but there are still signs of past activity in the field of solfatara / fumarola in weak behavior. The volcano when it erupts, will cause the magma contained in the magmar chamber under the volcano is pushed out as a lava or lava. In addition to lava flows, volcanic eruptions can cause mudflows, ash, hot clouds, forest fires, toxic gases, tsunami waves, and earthquakes. Therefore, for those around the volcano should often pay attention to the natural signs and warnings issued by the local responsible in the form of the following Status Level

DANGER (red): Indicates an immediate or erupting volcano or a critical catastrophic state, the opening eruption begins with ash and smoke, and the eruption may occur within 24 hours.

SIDE (orange color): Indicates a volcano that is moving towards eruption or causing a disaster, intensifying seismic activity, all data indicates that activity may soon progress to the eruption or lead to a catastrophic situation, and if the upward trend continues, Can occur within 2 weeks.

CAUTION (yellow): Any activity of any shape, there is an increase in activity above the normal level, increased seismic activity and other volcanic events, and slight changes in activity caused by magma, tectonic and hydrothermal activity.

SECURE (green color): No symptoms of magma pressure activity, basic activity level.

Here are 10 most active volcanoes in Indonesia based on the responsibility for the deaths caused by the eruption and the frequent activity that occurred recently.
