The Information .com / However, there have been several experts who say the quake on Saturday followed the pattern of large earthquakes that occurred over 700 years ago. According to geologists is the result of the domino effect caused by stress transferred along the fault.
The existence of a pattern was discovered by researchers few weeks ago, while doing fieldwork in the region. Today seems like a terrifying premonition because in addition to discover the historical pattern, the team led by Laurent Bollinger, the Committee on Alternative Energies and Atomic Energy of France, predicted a devastating earthquake would occur with exactly the same epicenter of the earthquake that took the covers the world press since Saturday.
The trail earthquake Inside the jungle, the team dug trenches along the main fault line of Nepal, a slit of 1,000 kilometers traveled the country west to east. Then fter buried in pits charcoal fragments to determine how and when the fault moved.
Although the ancient Nepalese texts mention several large earthquakes throughout history, find their traces on earth is a notoriously difficult task. In this sense, the monsoon rains wash the soil from the slopes and dense vegetation is covering the ground to make disappear the cracks caused by earthquakes.
But thanks to ‘trick’ of coal, experts were able to determine that the segment of the fault that analyzed had not moved in a while.
“We showed that this failure was not responsible for the great earthquakes of 1505 and 1833 and the last time moved was probably in 1344, “Bollinger, who presented the findings at the Geological Society of Nepal two weeks ago said.
A lot of tension Formerly the French team conducted a study on another part of the fault, east Kathmandu, and discovered that it trembled noticeably in 1255 and most recently in 1934 when Bollinger and his colleagues saw that over the years the tremors were repeated in segments of the fault, which could suggest the existence of a pattern, they worried greatly.
It therefore seems sadly found that tension in the western part of the fault after the earthquake of 1934 was finally released 81 years later. When a large earthquake occurs it is common that the voltage is transferred beyond the fault segment in the quake occurred. And apparently that was what happened in 1255.
And the tension accumulated over 89 years in the western segment of the fault eventually caused an earthquake in 1344.
Now is repeated history: the tension in the western part of the fault after 1934 was finally released after 81 years
Beyond the tragedy the team of scientists warned there could be more tremors in Nepal.. “Early estimates suggest that the 7.8 magnitude earthquake Saturday was probably not large enough to break the earth to the surface. So it’s likely that more tension is building up and see more tremors of this type west and south of this fault in the coming decades, “says Bollinger
