Surviving Tsunamis Tsunamis are as deadly as earthquakes, and are often connected. They both occur with little to no warning at all as well. After an earthquake, especially an earthquake originating in the ocean, near land, a tsunami is more than likely to occur. The 2004 Indian Ocean earthquake and tsunami was a devastating event that claimed the lives of more than 150,000 people in just one day. The tsunami generated by the Indian Ocean earthquake in 2004 was quite possibly the worst tsunami in history
so dangerous to humans A tsunami is a huge wave that can be up to 30 meters high. Tsunamis can be formed by landslides or volcanic eruptions underwater or when a meteorite crashes into the sea. Tsunamis occur, however, usually associated with earthquakes on the seabed due to movements in the earth 's crust or upper mantle. When this is done is created a vertical offset, the seabed drops or raised along a fault and this in turn creates a movement of large masses of water forming two tsunami waves
Ramana Murthy et al (2011) carried out field survey for the 2004 Sumatra tsunami along the Cuddalore coast using RTK GPS. The authors reported that a maximum inundation was about 2 km from the shore in the low lying areas. The authors pointed out that landform such as sand dunes acted as a barrier in the inundation of tsunami and variation of inundation from place to place. A post-tsunami field survey was conducted by Ramana Murthy et al (2012) for the Nagapattinam district, providing a dense sampling
What Causes Earthquakes? Earthquakes are probably the biggest disasters on this planet that have turned out to be deadly with respect to large numbers of people. This is the response to what causes earthquakes. Earthquakes have the ability to harm lots of people within minutes as well as wiping out around the world. The reason is that they begin to hit by minimum notification, and will often trigger huge destruction. This transport of seismic waves inside the Planet 's crust along with layer on
The tsunami in the Indian Ocean in December 2004 and the Tohoku Tsunami in March 2011 are just two examples of a number of natural disasters that have severely affected tourist destinations over the last decade. These examples highlight the vulnerability of tourists to disasters and emergency situations. The tourism sector is one of the largest industries in the world, in terms of employment and revenue. It faces challenges in coping with the impact of disasters, particularly in developing strategies
otherwise called a seismic ocean wave, is a progression of waves in a water body caused by the removal of a substantial volume of water, for the most part caused by quakes or volcanic emissions under the ocean. Out in the profundities of the sea, tidal wave waves don't drastically increment in tallness. Be that as it may, as the waves travel inland, they develop to ever more elevated statures as the profundity of the sea diminishes. These waves don't look like ordinary ocean waves, their wavelength
tremendous amounts of damage in historical earthquakes to residential structures all around the world. Liquefaction occurs in saturated soils, that soils in which the space between individual particles is completely filled with water called pore water. This water exerts as a pore water pressure on the soil particles that influence how tightly the particles themselves are pressed together. Prior to an earthquake, the water pressure is relatively low. However, earthquake shaking can cause the water pressure
in the ocean, inland sea and others. Each continent that existed in this world needs to know about the rate of frequency and the shape of its own to determine whether it is the kind of tsunami in the form of small or large tsunami. Most tsunamis are frequent in the Pacific Ocean that covers one third of the earth's surface and it also has been surrounded by a range of contiguous ranges, and ocean basins is also significant in island arc volcanic areas are often the onset of an earthquake. Among the
HUGE earthquake hit recorded as a 7.7-7.9 . Damaging buildings from left to right. Many poorly structured buildings collapsed causing 500 million dollars in total damage (1906 money) translated to about 8.2 billion dollars today. It was recorded that most buildings immediately caught fire which trapped the victims, about 25,000 buildings were burnt down from the fire, a total of about 490 blocks.At around 8:14 a Major aftershock hit making even more damaged building collapse. The earthquake and
April 2015, a major earthquake struck Kathmandu in Nepal. The quake, with a massive magnitude of 7.8, occurred because of converging tectonic plates. It was the worst earthquake recorded in the area for more than 80 years and was classified on the Mercalli Scale as VIII - very destructive. It lasted for more than 50 seconds, killing more than 9,000 citizens and injuring over 22,000 people. Scientific background Nepal sits on top of a volatile zone. Fifty million years ago the Indian and Eurasian Tectonic
and ecosystem are destroy too. Natural disaster usually happens suddenly. For example: earthquake happens suddenly when rock underground suddenly breaks along a fault. This sudden release of energy causes the seismic waves that make the ground shake. When two plates of rock are rubbing against each other, they will shake. There are many types of natural disasters, such as: volcanic eruption, tsunami, earthquake, hurricane, tornados, flooding, landslide, avalanches, drought, wildfire and many more
Chile experienced the second largest earthquake in its history, and according to the US Geological Survey the fifth largest in recent history. A magnitude 8.8 on the Richter struck Chile. The earthquake lasted about two minutes and affected 75% of the total population, which are approximately 12 million people out of the total 17 million. The epicentre was about 325 southwest of the capital the Santiago, 33 kilometres below the Pacific Ocean. The earthquake triggered a tsunami that affected about
Prince William Sound, Alaska earthquake was one of the second most powerful earthquakes recorded in the U.S. and North America. It took place on March 27 1964. The earthquake had a magnitude of 9.2, it lasted nearly four minutes. This was an extremely destructive earthquake in Prince William Sound and other areas of Alaska. In Western Canada, Oregon California and Hawaiian Island a Pacific-wide tsunami was produced which was destructive in. The death rate from the earthquake was about 128 people. Most
December, 2004 In Indonesia was a tragic month Because a tsunami hit and killed many people, in addition to all of the deaths, the tsunami destroyed everything in meulaboh. The author Richard lewis wrote the book to tell and to simulate the tsunami in the killing sea with two new characters, ruslan who once collaborated with sarah to save her little brother, peter. In the book The Killing Sea by Richard Lewis, Ruslan and Sarah have different viewpoints about what makes a good family. first The
CHAPTER-1 INTRODUCTION 1.1. GENERAL The term “progressive collapse” has been used to describe the spread of an initial local failure in a manner similar to a chain reaction that leads to partial or total collapse of a building. The fundamental characteristic of progressive collapse is that the final state of failure is disproportionately greater than the failure that originated the collapse. Progressive collapse as “the spread of an initial local failure from element to element resulting, finally
Samoan 2009 tsunami report: What caused the earthquake and tsunami? On Tuesday the 29th of September 2009, a huge tsunami hit Samoa – as well as several other islands – and impacted many, leaving a path of destruction [1]. Tsunamis are big waves that are generated from earthquakes, or volcanic eruptions that occur in the ocean [2]. The tsunami – in the case of Samoa – was caused by an underwater earthquake [1]. An earthquake is when the Earth’s surface shakes in response to the sudden release of
experienced earthquakes. Several areas hit by earthquakes in Indonesia were Nangroe Aceh Darussalam in 2004, Bengkulu in 2000 and 2007, Yogyakarta in 2006, and Padang in 2009. These earthquakes were not only resulted in the damage to the buildings, but also triggered other hazards, such as landslide, ground movement, and liquefaction. Among those hazards, liquefaction is categorized as a unique phenomenon that rarely happens. According to Kramer [1], liquefaction may happen under earthquake shaking
29th of September 2009, on a Tuesday morning Samoa was struck by a horrible tsunami that was triggered by an earthquake. These natural disaster s caused Samoan citizens to lose loved ones, had their homes stripped away from them along with their crops and how their economic environment was left damaged. This report will be explaining to you how these natural disasters affected Samoa. Earthquakes Earths crust is a hard-outer cover that is surrounding around the whole earth; it is made up of many, many
The impact of Tsunamis on the public and the future prevention The first Tsunami we know about was in 426 B.C., on the Malian Gulf. Humans have been struggling to contain the damage done by such natural causes. However, not only humans have suffered from these destructive causes, also animals and the environment have been damaged. Since 426 B.C. earth has had historical Tsunamis like Portugal and Galicia which were both higher than magnitude 6.3. Earth has recorded 87 historical Tsunamis since 426
In 1906, an earthquake hit San Francisco, California. More than 3,000 people died. The earthquake that hit San Francisco was one of the largest earthquakes in northern California. It struck the coast of Northern California.
