Geological and Mountain area disaster

Описание: In this video we will discuss about Geological and Mountain area disaster.
Natural risks are classed as geological hazards based on their causes. Geological catastrophes are natural disasters induced by geological processes, such as earthquakes, volcanic eruptions, tsunamis, and landslides.

Mountains and high ground cover around 20% of the area, while mountain dwellers account for about 10% of the world’s population. Natural catastrophes are widespread in the mountains because of large changes in height and high gravitational energy potential, and the crucial function of water in both liquid and solid phases.

There are three basic reasons why mountain landscapes are so dynamic.

The immense energy potential of the Earth’s gravity was gathered through the tectonic elevation of mountains.
They’ve been lifted to large elevations, which has resulted in a significant amount of orogenic energy.
High mountains are known for disrupting atmospheric water circulation, resulting in a substantial amount of water collecting in glaciers, snow cover, and loose deposits, which can contribute to landslides and mudflows.
Human activity, such as deforestation, extensive livestock grazing, road building, mining sector growth, and so on, exacerbates the dynamism of mountain landscapes.

Human operations such as drilling in over pressured zones pose a substantial danger. Therefore, better knowledge of geohazards, their preconditions, causes, and implications is essential for mitigation and prevention. In some circumstances, particularly in alpine locations, natural processes can trigger complicated catalytic events, such as an avalanche hitting a lake and triggering a debris flow with potentially hundreds of miles-wide ramifications or volcanism causing a lahar.
