Amazing Panorama From Catastrophic Event

Those who have enjoyed the beauty of Lake Toba may not be able to imagine the horror it caused in the process of its “creation”.

Once across the street corner near Parapat, a resort town on the edge of Lake Toba, blue expanse of water and the panorama of Samosir Island‘s stone hills will amaze you in an instant.

Scenic beauty of Lake Toba does not just happen. The largest volcanic lake in the world was formed from a super-massive series of geological and volcanic processes. There are at least three major volcanic eruption accompanied the formation of Lake Toba. The last eruption occurred 74,000 years ago.

Science magazine notes, the youngest eruption of Mount Toba is the largest volcanic event on Earth in the last two million years. It spewed 2800 kilometers cubic of magma, which 800 cubic kilometers of it flew into the atmosphere, blanketing the earth layer along the South China Sea to the Arabian Sea.

Stanley Ambrose, an anthropologist in University of Illinois at Urbana-Champaign, in 1998 introduced the theory of Toba disaster. Based on this theory, the eruption of Mount Toba changed the global climate. As a result, the human population decreased drastically. The line connecting the evolution of modern human species with other primates has been disconnected. This theory is debatable, but enough to illustrate the magnitude of the eruption.

The Caldera formed from three times eruption became Lake Toba. The last eruption perfected the formation of Lake Toba and Samosir Island, after the first eruption 800,000 years ago just formed the caldera around Parapat to Porsea and second eruption about 500,000 years ago formed the caldera in the area of Haranggaol and Silalahi.

Now, what left from the former volcanic event is just incredible natural beauty. Large caldera become a lake with a length of 100 kilometers and reaches 30 kilometers wide. Stone hills that surround the lake steep look exotic. Samosir Island is like a giant stone wall fortified the lake.

Amazed by this beauty, Prince Bernard of the Netherlands allowed his name used to “sell” Lake Toba. “Sell my name for this lake. I can’t describe how beautiful Lake Toba is, “said the prince while visiting Toba in 1996.

I’m sure you will allow yours to be sold too, once you witness the beauty of Toba.
