Samosir Island, Not Just a Big Island in the Middle of a Lake

These islands have their own uniqueness and beauty, especially the beaches. Almost all islands in Indonesia are located between or in the middle of the ocean. However, there is one island in Indonesia which is famous, and it is not located in the middle of the ocean.


This island is located in the middle of a lake. We certainly know or have heard of Samosir Island. This island is located in the largest lake in Indonesia, even Lake Toba is the largest volcanic lake in the world.

Because Lake Toba is a volcanic lake, Samosir Island is also known as Volcanic Island. Why is it called Volcanic Island?

According to research, the formation of Lake Toba and Samosir Island was due to a massive volcanic eruption around 69,000 to 77,000 years ago with a scale of 8.0 Volcanic Explosivity Index (VEI). An eruption with a Scale of 8.0 VEI can be described as a very powerful supervulcanological eruption that spewed more than 1000 km3 of eruptive material with an eruption height of up to 50 km. At that time, the earth's temperature was very low because of the eruption that reached the toposphere and stratosphere layers of the earth.

Samosir Island has an area of ​​about 63,000 hectares or approximately 640 square kilometers. The difference in area with Singapore is not too far away, about nine square kilometers, because Singapore covers an area of ​​approximately 72,150 hectares. Before becoming a separate autonomous region, Samosir Island was included in the Toba-Samosir (Tobasa) Regency but was divided into a separate Regency, namely Samosir Regency.

Samosir Island itself consists of six sub-districts from nine sub-districts in Samosir Regency. Because it is very wide, Samosir Island is included in the 10 largest islands in the world which are in the middle of a lake. Samosir Island is ranked 5th for this category.
