stock here, this quake was relatively shallow at 6kM, but also in a mountain range, and 80kM from Everest.

The long, curving mountain range that includes Nepal, Mount Everest, and Bhutan is part of the Himalayas, the highest mountain range in the world. Its formation is closely tied to the collision of tectonic plates.
How Were the Himalayas Formed?
Tectonic Plate Collision:
The Himalayas were formed as a result of the collision between the Indian Plate and the Eurasian Plate.
About 50-60 million years ago, the Indian Plate began moving northward at a rapid pace (geologically speaking) and collided with the larger Eurasian Plate.
This collision caused the crust to crumple and fold, leading to the uplift of the Himalayan range.
Continued Uplift:
The Indian Plate is still pushing northward into the Eurasian Plate at a rate of about 5 centimeters (2 inches) per year, causing the Himalayas to rise even today.
This ongoing tectonic activity is responsible for frequent earthquakes in the region.When Did It Happen?
Initial Formation: The collision began around 50-60 million years ago during the early Cenozoic Era.
Major Uplift: The significant uplift of the Himalayas started around 40-50 million years ago and has continued since, with much of the range reaching its present height in the last 10-20 million years.
Present-Day Height: Mount Everest and other peaks continue to rise slightly each year due to ongoing tectonic activity.Why Is the Range Curved?
The curvature of the Himalayan range is caused by the geometry of the collision zone:
The Indian Plate is shaped somewhat like a wedge, and as it presses into the Eurasian Plate, it creates a curve.
Variations in the strength and structure of the Earth's crust in different regions also contribute to this curvature.Key Features of the Region
Mount Everest:
The highest peak in the world, standing at 8,848.86 meters (29,031.7 feet).
Formed from marine sedimentary rocks that were uplifted and metamorphosed during the collision.
Nepal, Bhutan, and the Himalayas:
These areas are characterized by rugged, towering peaks, deep valleys, and diverse ecosystems.
The Himalayan range acts as a natural barrier, influencing the monsoon climate and biodiversity of the region.Significance:
The formation of the Himalayas is one of the most dramatic examples of plate tectonics in action and continues to be a dynamic and evolving geological feature. It serves as a living laboratory for understanding Earth’s geological processes.
