The Mont Everest continues to rise due to the collision of the Indian and Eurasian tectonic plates, causing a slow but steady push that lifts the Himalayan range, including the summit of Mount Everest.
The Earth resembles a giant puzzle made up of large slabs called tectonic plates, which are constantly moving. Mount Everest is located right where the Indian plate pushes against the Eurasian plate. The Indian plate is always slowly advancing northward, a few centimeters each year, and when these plates collide, the rock folds like a rug, thus forming the Himalayas range. This collision process continues to this day, which is mainly why Mount Everest keeps rising and gains a few millimeters each year.
The uplift is the nice term that geologists use to refer to the phenomenon that causes certain regions of the ground to rise upward. Beneath the Himalayas, two massive tectonic plates meet and constantly push against each other, forcing the terrain to climb. As the Indian plate moves northward, it slips beneath the Eurasian plate, gradually lifting it. The result: the Earth's crust bends and deforms, and voilà, the mountain range gains height. This is called folding, like when you press two pieces of carpet together and they form a bump. It’s slow, of course, barely a few millimeters a year, but over millions of years, that adds up to kilometers in altitude! Basically, it is these continuous underground movements that ensure the Everest grows steadily year after year.
Earthquakes play a key role in the elevation of Mount Everest. When two tectonic plates collide, the shocks cause sudden movements of the ground, sometimes pushing certain regions up by a few centimeters. Each earthquake is thus a sort of impulse that contributes to the overall rise of the Himalayan peaks.
In addition to this, there are also more subtle land movements, such as the slow and continuous sliding of the plates, which regularly add millimeters to the mountain's altitude. This slow and constant vertical erosion occasionally complements the unpredictable boosts provided by major earthquakes.
Today, to accurately measure the height of Mount Everest, we no longer just pull out the measuring tape! We mainly use satellite systems like GPS, which can determine altitude with impressive precision. Instruments like LiDAR also come into play: with its laser pulses, it accurately maps the relief and variations in terrain. Additionally, scientists utilize radar satellites that continuously monitor the slightest ground changes from space. These modern, ultra-precise tools allow us to see Everest rising little by little, millimeter by millimeter. Not easy to notice that from base camp, is it?
The major earthquake in Nepal in 2015 slightly shifted Mount Everest by several centimeters horizontally, clearly demonstrating the direct impact of earthquakes on mountains.
Although Everest is the highest mountain above sea level, Mauna Kea in Hawaii is actually about a kilometer taller when measured from its base underwater.
Modern surveys conducted with satellites and precision GPS now allow for the measurement of Everest's elevation with an accuracy of just a few millimeters.
The Everest is primarily composed of limestone, rock that was deposited millions of years ago at the bottom of an ancient sea, thus demonstrating the power of geological processes over time.
No, it will probably reach a maximum height as tectonic forces decrease and erosion takes over, thereby limiting its future elevation.
The altitude of Mount Everest is regularly checked using modern technologies such as GPS and laser telemetry, to study the effects of tectonic movements, earthquakes, and erosion on its elevation.
Yes, major earthquakes can significantly alter the height of Everest. For example, the earthquake in Nepal in 2015 is believed to have caused slight changes in the elevation of several peaks in the Himalayas.
Current technologies include high-precision differential GPS, satellite radar interferometry, and laser telemetry surveys, providing very accurate measurements of mountain altitudes.
Mount Everest rises on average by 4 to 10 millimeters per year due to the continuous movements of the Indian and Eurasian tectonic plates.
