The Eruption of RinjaniMountainSolve the Mystery of the World Climate

The Eruption of Rinjani MountainThe eruption of Rinjani even eight times is more powerful than the eruption of Krakatoa. European researchers found evidence that the volcanic eruption on the Lombok Island Samalashas changed in 1257. The changes in the weather in that year were marked by a chemical change in the surface of the polar ice Arctic and Antarctic.

Reported by the BBC, Tuesday, October 1st, 2013, the text of medieval Europe in 1257 noted that the climate of the earth suddenly cools and crop failure after Samalas Mountain or what is now known as RinjaniMountainerupted.
Researchers increasingly confident after they match sulfur, dust trail of ice at both poles of the data collected from the area of Lombok. Researchers also compared the radiocarbon dates, types and distribution of rock and volcanic ash issued and collaborate with the local history of Lombok in the 13th century.

And the resultis further reinforces the notion of researchers. “The evidence is very strong and interesting,” said Prof Clive Oppenheimer of the University of Cambridge.

Such as criminal investigation

While colleagues Oppenheimer, Prof. Franck Lavigne from University Pantheon Sarbonne, France said he was satisfied with the results of research although they had to work hard to track these findings, he admitted that the team as a criminal investigation.

“We do not know the perpetrator at first, but we had the time of the murder and no trace in the form of geochemistry at the core of the ice surface. It is possible for us to keep track of the volcano which is responsible for the events of the 13th century,” he explained.

Previously, researchers estimated that a source volcano weather event in 1257 was associated with volcanoes of Mexico, Ecuador and New Zealand. But lately, measurement and tracking geochemical and the date are not suitable.
Spit 40 Km Cubic Stone

The study team in Lombok show as much as 40 cubic miles of rock out perhaps it’s from SamalasVolcano while volcanic out in the sky and the high reachs more than 40 km.

Major eruption was a significant impact on climate change at the time. Medieval texts describe, in that century, the year after going on terrible summer in Europe. So the cold climate is continuous into rain and flooding.
Evidence was also corroborated by the findings of archaeologists framework of thousands of people were buried in mass graves in London. Framework calendar shows the burial took place in 1258.

“We cannot say for definite relation between the two events. But it clearly emphasizes the frame number,” said Prof. Lavigne.

Researchers believe eruptions Samalas at least for the latest massive eruption of Krakatoa in 1883, which resulted in a cloud of hot and massive tsunami and Tambora in 1815, which resulted in ‘the year without a summer’, a year after the explosion, due to the Tambora dust. Based on Citing Nationalgerographic page, 1257 eruption even eight times stronger than the eruption of Krakatoa.
