Tsunami is not just a single giant wave, it may even consist of ten or more waves which is then termed as: “Tsunami Wave Train” . Tsunami possesses kinetic energy and a mass of water which can cause devastation through kineticism and flooding. There is an international tsunami warning system and certain regional tsunami warning systems are also in placed.
Pakistan is shielded to a greater extent from the Tsunami of the Pacific Ocean and Bay of Bengal due to the Indian land mass, however, Tsunamis accruing in the Indian Ocean do effect us. In 1935 a Tsunami struck the Pakistan coast killing nearly 4000 people.
• Cyclone
Cyclone is basically a low atmospheric pressure region surrounded by high atmospheric pressure due to which there are powerful winds accompanied by rain. These are normally found in the tropical and temperate regions of the world. Cyclones are also known as Typhoons, Hurricanes and Tornadoes. Cyclones are normally found in the sea and finish off in the sea, however, certain cyclones intrude inland and cause death and destruction.
Pakistan has been lucky that Cyclones in this part of the world are not very frequent. This may have in part to do with the makeup of the Arabian Sea. However, Cyclones which have occurred in the past did cause considerable damage to the coastal areas affecting the livelihood of the people living on the coast.
• Flood
Flood is a state in which water level rises above normal along river banks and the coastal areas. They cause land
Hurricanes are mainly found in the Atlantic and Caribbean. Hurricanes in the Pacific are called typhoons. A more general term for these storms is a tropical cyclone. Hurricanes are named, and the naming process resets at the beginning
Natural disasters occurring from the climate change could be on the rise. Global warming has been rumored to be causing more hurricanes, typhoons, cyclones, heavier monsoonal rains that cause major flooding, mud slides, and other disasters worldwide. A tropical cyclone, also referred to as hurricanes, typhoons, or cyclones, depending on where in the world the cyclone is occurring, are one of the world’s grandest shows of energy provided by nature. Hurricanes are large, swirling, low pressure storms that have sustained winds of over 74 miles an hour and are formed over warm ocean waters (NASA, n.d.). The purpose of this paper is to discuss hurricanes
Tsunamis are caused by earthquakes underneath the ocean, which can results in gigantic waves that cause devastation and change the Earth’s surface by causing radiation and causing underwater landslides. In the article “Is Santa Catalina Island Sinking or Rising?” it describes how an effect of tsunamis. It states, “A tsunami could have struck the coast from Catalina when the underwater landslide occured” (Los Angeles Times 2). Therefore, tsunamis can strike coasts and can create landslides underwater, changing the ocean floor by creating caves and canyons. Also, tsunamis can wear away beaches. When giant waves crash into coasts of masses of land, they can wear away the coast. Finally, tsunamis can cause radiation. In the article “Dangerous Tsunami Threat off U.S. West Coast,” it explains, “It [the tsunami] also damaged a nuclear power plant, causing a meltdown and spreading dangerous radiation in the area” (Los Angeles Times). Consequently, tsunamis can destroy and interfere with human made buildings which may contain toxic gases which may be released into the air and cause damage the environment. Incidentally, damaging the environment can lead to killing plant and animal life, and the Earth in that area could potentially become barren and
Tsunamis occur when an earthquake happens in the ocean and the energy goes to the water creating huge waves. Tsunamis are very dangerous they can be so strong that they wash away the city, harm thousands, and cause hundreds of thousands to billions of dollars in damage. “A giant tsunami along the West Coast would wash away coastal towns, destroy U.S. Highway 101 and cause $70 billion in damage. More than 100 bridges would be lost, power lines toppled and coastal towns isolated. Residents would have as few as 15 minutes’ notice to flee to higher ground, and as many as 10,000 would die” (Dangerous tsunami threat off U.S. West Coast). This shows what kind of damage this geo-process can
The Tsunami that took place after the initial quake was caused by a portion of seabed rupturing upwards, and displacing a large portion of the water being displaced. This water traveled at 450 miles, at 8 feet tall, to the Chilean and Peruvian coast. Early viewers of the tsunami later reported waves being up to 10 feet tall. This rupture was believed to be caused by 2 unusually dense pieces of seabed that had been previously undetected by scientists, and consequently caused a large displacement of water. There were also small ruptures of seismic
Tsunamis occur when there is sudden movement in an extensive body of water such as earthquakes, landslides on the sea floor, major volcanic eruptions or meteorite impacts. The most common source of a tsunami is earthquakes, which are another type of geomorphic hazard that is caused by the friction and stress that tectonic plates put on each other. Tsunamis primarily occur in coastal or island regions where there is a tectonic border or what is known as the ring of fire. As shown in the diagram below the ring of fire is located along the coastal and island regions of the world.As a result of the Pacific Plate diving beneath the Eurasian plate, on March 11, 2011, there were 2 geomorphic hazards, a magnitude-9 earthquake struck north Japan, which caused a deadly tsunami that reached heights of 39 meters. The destructive dilemma was dubbed ‘The Great Sendai Disaster’. The earthquake was caused by multiple centuries of stress on the tectonic plates surrounding the island. The earthquake caused a tsunami that reached the height of 39 meters (128 feet). Japanese scientists had previously discovered that there was another tsunami just like the one in 2011 that took place in 869 AD. But their warning was unhindered. The tsunami, which occurred in 869 AD, was caused by the same tectonic fault as the 2011 tsunami. The epicenter of the earthquake was off the northeast cost of Japan leading to a devastating tsunami that killed many and left many wishing they were. The massive earthquake caused an upward wave that headed towards the city of Sendai. Researches have recently uncovered a thin layer of clay that lubricated the fault zone causing the deadly tectonic slip, thus creating a tsunami that could wipe out an entire city as it did in 2011.The aftermath of the 2011 tsunami and earthquake was not pretty; it caused many deaths, injuries, traumas, financial difficulties, destruction of property, health bills and the destruction of the landscape as a whole. The natural disaster caused nearly 16,000 casualties and there are an estimated 2,500 people still reported missing. Although drowning caused most deaths others include, crushed by debris, suicide and diseases caused by nuclear radiation (cancer) spilled from nuclear
Researchers have found that if a 9.0 magnitude earthquake strikes the U.S’s california there is a great chance that a tsunami will occur. If that happens it will cost over 70 billion dollars to repair. People around that area would only have a 15 minute notice to flee. It could destroy roads, power lines, bridges, towns, and so much more. Over 100,00 people would die at an estimate. There has been two major earthquakes. One of the earthquakes was on a sunday and at a 6.8 magnitude and the other one in 2005 was at a 7.0 magnitude. In california there has been six earthquakes over a 7.0 magnitude or greater in the past 100 years. Scientists have focused on the 9.0 earthquake and the tsunami in japan in
Unlike the Indian Ocean, the United States already have early warning systems in place, monitoring the pacific for any Tsunamis coming, evacuation roads are equipped in all cost hazards area less than 40 feet above the sea levels, and modern building are built to stand earthquake. However, the Tsunami that may hit the U.S is very different and more deadly waves than the one authority have been preparing for.
“Approximately 25 million people live in an area vulnerable to coastal flooding” (Environmental Protection Agency). The coastal activities generate 58% of the national gross domestic product. Activities that are involved are marine transportation, fish cultivation, tourism and recreation. The coastal area hold species and habitats that are essential to the ecosystem and society. The climate change affects the storm surge and precipitation, water temperature and coral reefs and shellfish.
The U.S. west coast is very vulnerable to tsunamis. If a big quake hits Oregon’s fault, then it can generate tsunami waves up to 98 ft high. A tsunami in this region can threaten lives and damage the area from California to Alaska. Future tsunamis in the Cascadian Subduction Zone off the Pacific Northwest are possible.
This image highlights that some regions in Sydney were suffering the flooding after the low pressure system swept down the east coast, Queensland, NSW, the ACT and Tasmania. Also the heavy raining and pale force wind leads numerous trees came down over the roads in Sydney. This circumstance has long-term impacts to the environment and the agriculture. Flooding in key agricultural production areas can lead to widespread damage to crops and fencing and loss of livestock. However, flooding has both negative and positive impacts. Positive impact is to increase fish production and recharge ground water. The negative impacts flooding leads too much sediment and nutrient, destroy habitat and impact the water
Pakistan, due to its diverse range of terrain, is susceptible to wide ranging hazards from droughts to floods and earthquakes to cyclones. Pakistan suffered a major drought from 1995-2000. Pakistan almost every year suffers from floods but the destructions faced in 2010 have changed parameters of our thinking. Pakistan has also experienced earthquakes ranging from moderate to severe in intensity. Despite all these hazards, Pakistan is yet to
In March of 2011, a magnitude 9 earthquake hit Japan, releasing a dangerous tsunami. Japan was not expecting the magnitude of the earthquake and tsunami, and endured much hardship after the disaster. The effects of the tsunami can still be seen in Japan today through its residents, economy, and through actions that have been taken to further protect residents from future disasters. Though the Japan 2011 tsunami is one of the most destructive tsunamis ever recorded, dangerous tsunamis continue to take place across the globe. The Japan 2011 tsunami not only affected the inhabitants of Japan, but also affected people around the world. After disasters such as this, each area must endure the aftermath of the disaster and recover from the effects.
This paper will discuss the differences between two different natural and man-made disasters. The disasters that will be discussed are Hurricane Katrina and the Deepwater Horizon oil spill. Additionally, this paper will look into the specifics of what constitutes a natural and man-made disaster. Specifically, this paper will look into each disaster to include the events surrounding them; the risks; and the assessments. Furthermore, this paper will look at some of the details of each disaster and why there was so much devastation. Finally, this paper will look at a few similarities, but mainly the differences between the two, and how the effects of each still linger today.
Bangladesh is one of the largest deltas in the world which is highly Penetrable to Natural Disasters because of its Geographical location, Flat and low-lying landscape, Poverty, Population density, Illiteracy, Lack of Institutional setup etc. Similarly the Physical, Social as well as Economic states of Bangladesh are very typical to any of the most Penetrable countries to Natural Disasters in the world . The total land area is 147,570 sq. km. consists mostly of Floodplains (almost 80%) leaving major part of the country (with the exception of the north-western highlands) prone to flooding in the rainy season. Moreover, the adverse affects of Climate Change – especially High Temperature, Cyclones and Sea-level Rise, Storm Surges, Salinity Intrusion, Heavy Monsoon Downpours etc. has aggravated the overall Economic Development scenario of the country to a great extent.
