 About Sumatra

 

Sumatra(Indonesia): Sumatera) is an island in western Indonesia n Indonesia and part of the Sunda Islands. It is the largest island that is entirely in Indonesia (two larger islands, Borneo and New Guinea, are shared between Indonesia and other countries) and the sixth largest island in the world at 473,481 km² (including adjacent islands such as the Riau Islands and Bangga Belitung Islands).

Sumatra is an elongated landmass spanning a diagonal northwest-southeast axis. The Indian Ocean borders the west, northwest, and southwest sides of Sumatra with the island chain of Simeulue, Nias and Mentwai bordering the southwestern coast. On the northeast side the narrow Strait of Malacca separates the island from the Malay Peninsula, an extension of the Eurasian continent. On the southeast the narrow Sunda Strait separates Sumatra from Java. The northern tip of Sumatra borders the Andaman Islands, while on the lower eastern side are the islands of Bangka and Belitung, Karimata Strait and the Java Sea. The Bukit Barisan mountains, which contain several active volcanoes, form the backbone of the island, while the northeast sides are outlying lowlands with swamps, mangrove and complex river systems. The equator crosses the island at its center on West Sumatra and Riau provinces. The climate of the island is tropical, hot and humid with lush tropical rain forest once dominating the landscape.

Sumatra has a wide range of plant and animal species but has lost almost 50% of its tropical rainforest in the last 35 years, and many species are critically endangered such as the Sumatran Ground-cuckoo, Sumatran tiger, Sumatran elephant, Sumatran rhinoceros, and Sumatran orangutan. Deforestation on the island has also resulted in serious haze over neighbouring countries, such as the 2013 Southeast Asian haze causing considerable tensions with affected countries such as Singapore and Malaysia.

Srivijaya was a Buddhist monarchy centred in what is now Palembang. Dominating the region through trade and conquest throughout the 7th to 9th centuries, the empire helped spread the Malay culture throughout Nusantara. The empire was a thalassocracy or maritime power that extended its influence from island to island. Palembang was a center for scholarly learning, and it was there the Chinese Buddhist pilgrim I Ching studied Sanskrit in 671 CE before departing for India. On his journey to China, he spent four years in Palembang translating Buddhist texts and writing two manuscripts.

Srivijayan influence waned in the 11th century after it was defeated by the Chola  Empire of southern India. At the same time, Islam made its way to Sumatra through Arabs and Indian traders in the 6th and 7th centuries AD. By the late 13th century, the monarch of the Samudra kingdom had converted to Islam. Marco Polo visited the island in 1292, and  Ibn Battuta visited twice during 1345–1346. Samudra was succeeded by the powerful Aceh Sultanate, which survived to the 20th century. With the coming of the Dutch, the many Sumatran princely states gradually fell under their control. Aceh, in the north, was the major obstacle, as the Dutch were involved in the long and costly Aceh War (1873–1903).

Sumatra came under the control of the Dutch East Indies and became a major producer of pepper, rubber, and oil. In the early and mid-twentieth century, Sumatran academics and leaders were important figures in Indonesia's independence movements, such as: Mohammad Hatta (the first vice-president) and Sutan Sjahrir (the first prime minister).

The Free Aceh Movement fought against Indonesian government forces in the Aceh Insurgency from 1976 to 2005. Security crackdowns in 2001 and 2002 resulted in several thousand civilian deaths

The Great Sumatran fault (a strike-slip fault), and the Sunda Megathrust (a subduction zone) subduction zone), run the entire length of the island along its west coast. On 26 December 2004, the western coast and islands of Sumatra, particularly Aceh province, were struck by a tsunami following the Indian Ocean earthquake. More than 170,000 Indonesians were killed, primarily in Aceh. Other recent earthquakes to strike Sumatra include the 2005 Sumatra Earthquake and the October 2010 Sumatra earthquake
