Approximate extent of the Alpide Orogenic System

The Alpide belt or the Alpine-Himalayan orogenic belt[1] includes an array of mountain ranges which extends along the southern margin of Eurasia, stretching from Java to Sumatra through the Himalayas, the Mediterranean, and out into the Atlantic. It includes the Alps, the Carpathians, the mountains of Anatolia and Iran, the Hindu Kush, and the mountains of Southeast Asia. After the Pacific Ring of Fire, it is the second most seismic region in the world, with 17% of the world's largest earthquakes.[2]

The Alpide belt is being created by ongoing plate tectonics. The belt is the result of Mesozoic to Cenozoic to recent closure of the Tethys Ocean and process of collision between the northward-moving African, Arabian and Indian plates with the Eurasian plate.[1]

Main ranges[edit]

Indonesia lies between the Pacific Ring of Fire along the northeastern islands adjacent to and including New Guinea and the Alpide belt along the south and west from Sumatra, Java and the Lesser Sunda Islands (Bali, Flores, and Timor). The 2004 Indian Ocean earthquake just off the coast of Sumatra was located within the Alpide belt.
