Mount Raksa on the remote island of Panaitan is home to one of the oldest Hindu statues in Indonesia.

Why are there so many volcanoes in Indonesia?

Indonesia is located on the Pacific Ring of Fire and has no less than 400 volcanic cones including at least 128 active volcanoes!

This concentration of volcanoes in Indonesia is explained by the subduction of oceanic plates under less dense plates, which is also the cause of frequent earthquakes and tsunamis.

It is in Indonesia that has occurred:

The most colossal eruption of all time (about 75,000 years ago) that later formed the huge caldera now home to Lake Toba in Sumatra. The 2 most powerful eruptions of the last millennium, the eruption of the Tambora volcano and the eruption of Samalas (ancestor of the Rinjani volcano and its caldera). One of the most famous, the eruption of the volcano Krakatau in 1883.

But Indonesia is also one of the most fascinating archipelagos in the world! a veritable cultural and linguistic melting pot of peoples of different religions and beliefs and with an estimated population of 250 million people. With an area of ​​1,919,440 km2, the archipelago has 54,716 km of coastline! Indonesia is the largest archipelago in the world, the country extends over 5 120 km at the equator (it is equivalent to the distance that separates Paris from Montreal to Canada, or Paris from Almaty to Kazakhstan !). The archipelago has 3 time zones. Made up of about 17,500 islands of which only 922 are inhabited, Indonesia has large wild areas which gives the country a great biodiversity and offers a kaleidoscope of landscapes that will be immortalized in Photo. Each of its islands is a journey in itself, an unprecedented experience.
