The idea that natural disasters and other severe weather events are getting worse than they used to be is a common misconception. Although the number of severe weather events has increased in recent years, this does not necessarily mean that each event was more intense or powerful than those we saw before. This article debunks ten myths about natural disasters so you can better prepare yourself for when one strikes your area!
What is a natural disaster?
A natural disaster is an event that causes widespread destruction or loss of life. Causes of natural disasters could be flooding, hurricanes, tornadoes, famine, disease outbreaks, earthquakes, tsunamis.
What are 10 examples of natural disasters?
An earthquake is the sudden shaking of the Earth caused by an influx of seismic waves. They are the product of plate tectonics, so that they can happen anywhere in the world. Earthquakes release kinetic energy, the same form of energy that fuels heavy machinery.
Sinkholes are common in locations where the rock below ground level is limestone, carbonate rocks or salt beds. As this type of material dissolves over time and space develop underground providing support for above-ground structures but not enough to stop them if there was ever an issue with too much weight on one side - which would lead inevitably towards collapse! This may happen suddenly when you least expect it. The most damage from sinkholes tends to occur in Florida, Texas, Alabama, Missouri, Kentucky, Tennessee, and Pennsylvania.
Floods are natural disasters that affect oceans, lakes, and rivers. Floods can happen all over the world. Flooding is usually caused by heavy rain, and floods are hazardous and damaging to homes and property.
Tsunamis most often occur in the Pacific Ocean, although they can happen anywhere with a coastline. Tsunamis happen when sudden changes in depth or pressure cause a water surface to move violently. It can be caused by landslides on land, violent volcanic eruptions, and earthquakes underwater. Tsunamis are also called tidal waves when they happen in the open ocean, translating from Japanese language the word meaning "harbor wave."
Tornadoes come from thunderstorms. They go from the thunderstorm and chase the ground generating a rotating force of the air. Tornadoes can be dangerous as they can cause tornadoes, strong winds, lightning strikes, flooding, and other natural disasters. A tornado starts with a funnel-shaped cloud above ground level connected to an extensive storm system on the ground caused by an instability in the atmosphere that spins rapidly around its vertical axis.
Hurricanes are violent weather systems that rotate around a center of low atmospheric pressure. They are often called cyclones in the Indian Ocean or hurricanes elsewhere. Hurricanes form over warm ocean water when their sustained winds have reached 39 miles an hour. The outer layer of hurricanes is rotating air currents called wind cells. The winds at the surface are generated by the differential heating between the ocean and land and rotation of the Earth, which creates a system of orbiting winds, with hurricanes and many other storms at its center.
Volcanoes are caused by the buildup of pressure inside the volcanoes. They are formed when hot magma rises to the surface. Volcanoes are one of the most destructive natural disasters because they release molten rock, ash, and toxic gasses into the air. This kind of volcanism has been linked to nearly 75% of all extinctions over the past 500 million years.
Wildfires can be caused by several factors, including lightning, campfires, and other artificial sources. Lightning is the leading cause of wildfires in Canada and the United States. In Africa and Australia, lightning fires are not as prevalent because the climate is dryer. Fires that start from animals or people are called human-caused fires.
Heatwaves are weather anomalies that cause an extreme temperature increase in a short period. It can last for days or weeks, and they often lead to fatalities due to the intense temperatures.
Blizzards are a type of winter storm that is characterized by heavy snow and strong winds. The winds can disrupt natural phenomena, such as the formation of ice sheets. Blizzards may also have a low-visibility effect due to the amount of snow being carried by the wind.
Here are the top 9 Myths about natural disasters
Myth 1: People are dying in disasters less frequently and at a lower rate than ever before. While that may be true for some types of disasters, it is not the case with earthquakes and tsunamis—the very events people think about when they talk about natural disasters. For decades now, we have been experiencing more and more giant earthquakes as well as catastrophic tsunamis (or tidal waves).
Myth 2: People are dying in disasters less frequently and at a lower rate than ever before. While that may be true for some types of disasters, it is not the case with earthquakes and tsunamis—the very events people think about when they talk about natural disasters. For decades now, we have been experiencing more and more significant earthquakes as well as
In the first half of the 20th century, every year in Japan, flooding and typhoons killed many individuals. In Japan, floods caused around one death out of 100,000 people each year from 1950 through 1960. The typhoon mortality rate fell to 0.08 per 100,000 by 1960 as a result of significant infrastructure investment, In the Philippines, Typhoon Haiyan caused the devastation of thousands of families, and the threat of such calamities is on the rise in many parts of the world.
Myth 3: Floods and storms are the most dangerous risks to humans.
Floods and storms are the most dangerous risks to humans. Floods accounted for just five percent of disaster-related deaths between 1985 and 2004. Earthquakes caused 60 percent—and heatwaves took nearly as many lives as earthquakes did during that same period. But climate change is likely to make these extremes worse in the future--and, as a result, more destructive as well.
Myth 4: The worst-off countries suffer the most fatalities and losses to their economies.
By a chain of circumstances, as the world grows more crowded and developed, particularly in the developing world, the number of people and assets moving to regions exposed to hazards almost always rises. Many middle-income countries are also highly exposed to risks owing to their geography. India, China, Thailand, the Philippines, and Mexico are all middle-income nations.
There are several challenges associated with studying the costs of climate change:
- It is difficult to attribute specific weather events or extreme heatwaves to climate change to assess whether these would have occurred without human influence on the environment.
- Even when an event can be attributed directly to global warming, scientists cannot predict its future probability and severity.
- It is challenging to quantify the costs of climate change as some impacts will be positive and others negative.
In middle-income nations, 1.1 million people have died in disasters since 1980, compared to only 1 million in low-income countries, with the majority of them residing in sub-Saharan Africa. The economic effect on middle-income nations is also more incredible: it averages 1 percent of GDP compared to 0.3 percent in low- and zero.
Myth 5: Disasters affect both men and women equally.
In reality, disasters often disproportionally affect women and girls. They may be more vulnerable to sexual violence during a disaster and the long-term effects of trauma from witnessing death or experiencing physical harm. In addition, it can take them longer to recover since they have additional responsibilities for children and other family members that men do not have.
The differences in death rates between genders are frequently most significant. Women accounted for six out of every ten fatalities during Cyclone Nargis in Myanmar in 2008 and over eight of every ten deaths in Ahmedabad, India, during the 2010 heatwave. Women also tend to be more affected by disasters that are slow-moving, such as droughts.
Myth 6: Global warming is one of the most common reasons for catastrophes.
While global warming has been a topic of much concern, it is not the cause of every extreme weather event. In fact, in many cases, other factors contribute to these events. For example, while researchers have found links between climate change and heatwaves, they haven't been able to find any link when it comes to the recent hurricanes.
The Intergovernmental Panel on Climate Change (IPCC) has determined that human exposure to hazards and people's vulnerability are the significant causes of changing disaster impact trends. It's tough empirically to measure the precise influence of climate change on any particular catastrophe. Still, the IPCC is clear that disasters affected by climate change are expected to grow in intensity from 2030 onwards. Based on this study, two main factors contribute to the severity of a hurricane: ocean temperature and wind speed.
While warmer water helps feed more energy into the system, faster winds can help sustain stronger storms for more extended periods. Overall, these conditions naturally lead to an increased risk of catastrophe in areas already prone to flooding due to their geography.
Myth 7: Nothing may be done to stop the ever-increasing number of calamities.
It is important to note that myth six does not take into account the efforts of our ancestors. A lot has been done to stop natural calamities. For instance, there are more regulations on building homes in areas where natural disasters are most likely to occur. A lot has also been done to make infrastructure more resistant to natural disasters. There are also a lot of preventative measures that we can take: these include forest conservation, removal of sediment, and modernization of systems, including roads and bridges.
Every year, floods and typhoons killed hundreds of people in Japan throughout the first half of the 20th century. In Japan, the typhoon mortality rate was about 1 out of every 100,000 people in the 1950s. Thanks to significant investment in defenses, comprehensive land-use planning, legislation, and a reduction from 1960 onwards to 0.14 typhoons per 100,000 people in Japan.
Japan is not the only country that has successfully controlled natural calamities. The Netherlands regularly experiences floods and droughts but still thrives as an agricultural nation. This can be attributed to its ability to build dams, dykes, and water reservoirs which minimize flooding risks while optimizing land use for crop management.
The Netherlands is not the only country to have learned from its mistakes and successfully minimized the effects of natural disasters. Many other countries have also minimized harm by building dams, dykes, etc., which can be seen in this list.Myth 8: Ineffective measures to reduce the number of natural disasters.
This is one of the most common myths regarding climate change. Many people believe that by adopting effective measures, we can reduce the number of natural disasters happening every year. This may be true for some types of natural disasters (for example, hurricanes), but it's not an easy task to significantly minimize other types of natural disasters (for example, droughts).
Myth 9: The world is facing an ever-increasing rate of disaster occurrences.
This is a critical point in the argument against climate change, but it does not reflect scientific consensus.
The predictive models used to estimate future disaster rates indicate that many kinds of disasters have decreased since 1950, while others have remained relatively constant. For example: Storms and floods have become less frequent. Tornados and hurricanes have stayed about the same.
This is a critical point in the argument against climate change, but it does not reflect scientific consensus. The predictive models used to estimate future disaster rates indicate that many kinds of disasters have decreased since 1950, while others have remained relatively constant.
7 Ways to Reduce Natural Disasters
- Prepare for storms by stocking up on supplies
- Check your insurance coverage to make sure you're protected against natural disasters
- Make a plan with your family in case of an emergency, including meeting places and how to contact one another
- Install storm shutters or hurricane-resistant windows in your home if possible
- Secure all outdoor objects before a storm arrives - this includes children's toys, furniture, grills, bicycles, patio umbrellas, and more
- Take steps to protect the foundation of your house from flooding damage - this can include installing sump pumps or raising the ground level outside your home by adding dirt or sandbags around it
- Have disaster recovery kits on hand to store essential documents, supplies, and other essentials for you and your family
Conclusion about natural disaster myths
Many people believe that natural disasters are just one-time events. The truth is, they happen all the time, and we can't predict them like we thought we could.
Here are highlights on how to reduce Natural Disasters:
- Get your home ready by following these guidelines for hurricane season
- Prepare yourself with emergency kits in case of an earthquake or tornado strike
- Be aware of potential flooding/landslides during monsoon season (or any other time!)
- Volunteer at local shelters if there's ever a disaster nearby; it helps those impacted feel less alone + gives us volunteers some peace of mind too! If you want more information
