Nationalgeographic.co.id—Mountains Himalaya it also “breathes” like humans. There is a time Mountain–Mountain in these areas grow expands, but there are times they also shrink. Peris like the human chest cavity when inhaling and exhaling.
In principle, if we can advance our planet’s clock rapidly, which means accelerating its rotation, the earth’s surface will stretch because of the rotating activity. Continents would run all over the world, oceans would open and close, and Mountain–Mountain will just soar into the sky.
However, after Mountain–Mountain ride, Mountain–Mountain it will also periodically sink again when the pressure from tectonic collisions triggers earthquakes. These events occur in one cycle, like a giant rocky chest that sucks in an uneven breath, explains Luca Dal Zilio, a geophysicist at the California Institute of Technology in the United States.
The forces that drive this cycle are very complex, and nothing is more real than at the 1,400 -mile jagged peak that forms Himalaya. Understand the basics that underlie the area Himalaya It is very important to understand the local risk of earthquakes that threaten hundreds of millions of people living in the shadows mountains the.

In a recent study paper published in the journal Nature Reviews, Dal Zilio and his colleagues have combined the results of more than 200 previous Himalayan geological studies to pin down the intricate mechanisms behind the mountain’s geological respiration.
As similar geological “breaths” have been documented around the world, this new work is key to understanding the processes that make up Earth’s many mountains and figuring out the risks that these mountains may pose.
The vast expanse of the Himalayas and their geological complexity make them a great natural laboratory, said one of the study’s co-authors, Judith Hubbard, a structural geologist at Nanyang Technological University (NTU) in Singapore.
“It’s almost like Earth conducting experiments for us,” he told National Geographic.
The planet’s tectonic plates are constantly moving, reshaping their surface as they split and collide. The Himalayas are the dramatic result of one such tectonic pile some 50 million years ago, when the Indian continental plate crashed into the Eurasian plate.
To this day India continues to move north at a rate of nearly two inches every year. But the land doesn’t slide smoothly under Eurasia. And as India pressed, the Eurasian plate swelled and swelled.
This process pushed the mountains slightly higher into the sky for long periods of time. Eventually, the pressure reached its breaking point, and the land shifted into a ground-shaking earthquake — a geological version of breathing or coughing.
This cycle was seen as deadly in 2015. At that time, an earthquake measuring 7.8 on the Richter scale caused swaths of the Himalayas to sink nearly two feet.

What the researchers noted, however, were the different zones in the sequence mountains Himalaya can produce different types or intensities of breathing. To understand this complexity, scientists must piece together the processes of formation Mountain–Mountain occurring on drastically different timescales –from a slow decrease in plate tectonic velocity to an almost instantaneous earthquake shift.
This is not an easy thing. Different measures are needed to understand each phenomenon, often involving researchers from different specialties geology.
From mebuah research papers reviewed in Education Recently, Hubbard and his colleagues found that subsurface curvature around a section of the fault shifted during the 2015 earthquake. This implies that the structures are in mountains this limits the level of damage as well as the magnitude of the earthquake.
Other structures formed over the centuries may exist along the length of the region, and they can also limit how far an earthquake can propagate near the surface, Dal Zilio said.
Papers Education this review itself highlights how gathering the wide variety of information available can help scientists develop a more complete understanding – and more robust computer models – of earthquakes in Himalaya as well mountains other. It’s not only about how the earthquake’s reach grows, but also about its deadly potential.
“The ultimate goal is to find out what types of earthquakes we can expect and what kind of damage they will produce,” said Hubbard, adding that doing so would require significant detective work.
