What is the impact of earthquakes on life and property?
Some of the common impacts of earthquakes include structural damage to buildings, fires, damage to bridges and highways, initiation of slope failures, liquefaction, and tsunami.
What are the factors that influence the human toll of earthquakes?
There are seven main factors that determine the impact of an earthquake:
- Distance (along the surface and depth)
- Severity (measured by the Richter scale)
- Population density.
- Development (building quality, financial resources, healthcare, infrastructure, etc.)
- Communication links.
How does poverty contribute to vulnerability to natural hazards?
Clearly, poverty is a major contributor to vulnerability. Poor people are more likely to live and work in areas exposed to potential hazards, while they are less likely to have the resources to cope when a disaster strikes. In richer countries, people usually have a greater capacity to resist the impact of a hazard.
What are three positive effects of volcanoes?
Positive effects Geothermal energy can be generated in areas where magma lies close to the surface. This is good for increasing our renewable energy use. Ash ejected by the volcano acts as a good fertiliser for soils. Volcanoes attract many tourists, who enjoy the dramatic scenery that they produce.
Which country is most prone to natural disasters?
India
What is vulnerability and risk of disaster?
It considers the probability of harmful consequences, or expected losses (deaths, injuries, property, livelihoods, economic activity disrupted or environmentally damaged) resulting from interactions between natural or human induced hazards and vulnerable conditions.
Why some earthquakes are worse than others?
Earthquakes are more intense the faster the planet’s crust slams together, which explains why the shaking causes so much damage in some of the most populated areas around mountain chains. One reason for this connection is that when two plates come together quickly, the area over which an earthquake occurs is larger.
Why are the effects of earthquakes worse in developing countries?
Why do earthquakes in other countries seem to cause more damage and casualties than earthquakes in the U.S.? There is more damage and more deaths from earthquakes in other parts of the world primarily because of buildings which are poorly designed and constructed for earthquake regions, and population density.
What are the 3 main factors that determine the amount of earthquake damage?
When an earthquake strikes, the intensity of earthquake shaking determines the severity of damage. In turn, the main factors affecting earthquake shaking intensity are earthquake depth, proximity to the fault, the underlying soil, and building characteristics—particularly height.
Why are poor countries more vulnerable to natural disasters?
Poor people are more often affected by natural hazards because they often have to settle in risky areas, for two major reasons. First, at risk areas may be more attractive when they offer economic opportunities, public services or direct amenities, and higher productivity and incomes (Hallegatte 2012).
Why do people live near earthquakes?
Often people live in these zones because they decide that the advantages of the place outweigh the risks. Most volcanoes and earthquake zones are safe for long periods in between eruptions or earthquake events. Frequently tectonic events can be adjusted to and are considered by the residents as being predictable.
How do earthquakes and volcanoes affect human life?
Earthquakes and volcanoes are destroying the environment at a rapid rate because they are both causde by tectonic activity. Volcanoes erupt lava and ash, burning and scarring the environment. Earthquakes shake the land, causing cliffs, and destroying towns.
