Natural Hazards

Hey guys, I hope you are all doing good. Here’s my new post on Natural Hazards:

What are Natural Hazards?

They are events which are caused Naturally or when there is a change in the Earths Geography.

Examples of Natural Hazards:

  • Flood :
    • Floods occur when the water level rises more than the ground can absorb.
    • Flash Floods are the best example; sudden storms unleash an extra torrential downpour causing the water to rise.
    • The force could knock down a car, in fact, most of the deaths in floods involve vehicles.
    • Floods occur many different ways, e.g., Heavy rain and thawing snow can also cause Floods.
    • Storm surges from Storms and tsunamis can also be the reason of flood.
    • Landslides and mudflows can displace large volumes of water, which cause dams to break and levees to fail and destroying cities.
    • Example of a Flood:
      • China Flood 1931 :
      • This Flood is known as the world’s deadliest flood ever with casualties of 1,000,000 – 4,000,000 and is one of the world’s most fatal floods.

  •  Drought:
    • The signs are slow and subtle, the land dries up, water level drops and rain does not come, and drought takes over.
    • Drought occurs typically when water is used more than it is replenished (refilled).
    • It is a tie between supply and demand, and it also has both Human and Natural Factors.
    • Drought occurs when a change in wind patterns causes high-pressure systems to last for months or years
    • When the demand for water does not stop drought starts to take place, crops wither and die; forest fire spread rapidly.
    • The damage to the environment has vast consequences
    • Example of a Drought:
      • The dust bowl drought
      • The dust bowl drought was the most destructive drought the USA ever witnessed with damage of about 50,000,000 acres of land

  • Avalanche:
    • At very high speed, an avalanche can rumble an entire mountain and carpet everything in its way in the snow.
    • Avalanches come in many different forms, one of them is Sluff which is a loose snow avalanche.
    • Slab avalanches are avalanches in which huge parts of a mountain crack.
    • Avalanches cause when there are sudden changes in snowfall, wind or rapid changes in temperature.
    • 90% of avalanche deaths are caused because victims or people accidentally activated avalanches.  
    • Example of Avalanche:
    • Yungay, Peru:
      • An avalanche on Mount Huascaran, Peru burying the town of Yungay in a carpet of snow and ice in May 1970 with casualties of about 18,000 people.
    • Plurs, Switzerland :
      • A Swiss town of plurs was swept by an avalanche in September 1618 taking lives of about 2000 people.

  • Earthquakes:
    • Earthquakes occur when two plates rub against each other.
    • There are four types of different earthquake, each with its violent way.
    • Most earthquakes occur along the edge of oceanic and continental plates.
    • The strongest earthquake was in 1960 Valdivia with a magnitude of 9.6/9.7
    • The damage caused by an earthquake depends on its depth and fault
    • Example of Earthquake:
      • Pakistan 2005
      • On October 8, 2005, an earthquake with a magnitude of 7.6 shook the Kashmir region and parts of Pakistan, India, and Afghanistan. More than 80,000 people died while estimated 4 million were left homeless
