The earthquake that devastated Japan on Friday, March 11, 2011 was one of the worst disasters to occur in twenty-first century. Not only did the earthquake itself affect the nation, but it also suffered through the following tsunami that occurred afterwards.
Though earthquakes are pretty hard to predict, Japan is normally pretty savvy when preparing for the worst for these tectonic storms. Japan is certainly no stranger to earthquakes, as it experiences upwards of 1,500 of them every year (Israel). As Japan is located along the so-called “Ring of Fire” in the Pacific ocean, earthquakes are just a part of life. This particular earthquake was not even the worst Japan has had. In 1923, the Great Kanto Earthquake killed more than 100,000 people (Oskin). The 2011 earthquake came as a shock to scientists in Japan, however for two reasons. One being that a large magnitude 7.2 earthquake struck just two days before and was even followed by a tsunami (Sorkhabi). Normally, when such a large earthquake occurs, it signifies to people that the big earthquakes are done, at least for that time; nobody fathomed that this would be the precursor to such a devastating event. The other reason was that such a large earthquake was unprecedented in Japanese history; Japan had suffered through some very serious earthquakes over the years, but generally, Japan learned from these disasters and made several preparations over the years (in roads, infrastructure, etc.) to handle similar events. Simply because it never happened, nobody figured that an over-nine magnitude earthquake would occur (Sorkhabi).
The epicenter of the earthquake occurred off the shore of Japan along something called a subduction zone. Subduction zones are places where tectonic collis...

...nd a large recession in the ocean beyond normal tide levels accompanied by a loud roar (Singh). Second, people should know that the higher in elevation you can get during a tsunami, the greater your chances are for survival. If you are in a building with more than one story, get to the highest level of the building you can access. If you are in a one-story building when a tsunami is about to occur, flee to higher ground if there is time (Singh).
Japan, a country that has dealt with earthquakes and tsunamis basically since its founding, was very nearly crippled by the effects of the natural disaster that occurred on Friday March 11, 2011. It is the single largest earthquake ever to hit Japan in terms of magnitude, and serves a reminder to both Japanese citizens and people around the world that we should always be prepared for the worst and to expect the unexpected.
The tsunami in Thailand that occurred on December 26, 2004, was by far the largest tsunami catastrophe in human history. It was triggered by a magnitude 9.1-9.3 earthquake along the Indian-Australian subduction zone off the northern coast of Sumatra. The tsunami waves traveled primarily in the east to west direction and caused major damage along the coasts of southern Thailand. Unpredictably, it was a violent earthquake beneath the sea that initiated the massive waves and struck more than a dozen countries in Southern Asia. It also destroyed thousands of miles of coastline and even submerged entire islands permanently. Throughout the region, the tsunami killed more than 150,000 people, and a million more were hurt, homeless, and without food or drinkable water, making it perhaps the most destructive tsunami in the modern history. In spite of peninsular Thailand's location facing the northern part of this subduction zone, the lack of any written historical records, together with the lack of any major local seismic activity, the tsunami caused thousands of fatalities and huge economic losses in the popular tourist regions in Thailand. Immediately after the disaster, numerous organizations and individual citizens have helped out and contributed to this devastating tsunami. Indeed, the tsunami in Thailand was a worldwide event, with significant wave action felt around the world. In this context, I am focusing more on the key features of the tsunami’s natural causes, the psychological effects on citizens, the perspective of socio-economic impacts and the consequences of the tsunami calamity.
Earthquakes in California are certainly not a surprise. What is a surprise is their unpredictability and randomness. Geologists say there is roughly a 50 percent chance that a magnitude 8 or more quake will hit the Los Angeles area sometime over the next 30 years. And, over the past twenty years, the Los Angeles area has witnessed several earthquakes, and in particular, two that were quite devastating; the 1971 San Fernando earthquake, and the January 17, 1994, Northridge Earthquake. Given the certainty that earthquakes will occur, they still seem to come as a surprise, and leave many communities unprepared to deal with their aftermath.
A tsunami is a series of waves “created by an underwater disturbance such as an earthquake, landslide, volcanic eruption, or meteorite” (ready.gov). Tsunami waves are quite different from normal waves. Once a tsunami is set in motion there is no way to really “prevent” it fully, or to stop such an event. Precautionary steps can be taken, such as in Japan where a sea wall was built to protect people and property. However, this was a futile attempt since in 2011 a tsunami was able to surge over the wall, with the water building up and rushing over the top. The lesson learned is that one should not
Earthquakes have been recorded throughout history for thousands of years. Even before seismographs in early times, there are records and accounts of mysterious ground shaking. Earthquakes occur when rocks break along an underground fault (UPSeis, 2007). This, in return, causes vibrations through the earth which causes ground shaking. The magnitude of the shaking varies depending on how great the movement along the fault is; the greater the movement, the bigger the earthquake. Some earthquakes are huge and cause significant damage, while others are small and cause little or no damage what-so-ever. Earthquakes are unpredictable, and can happen at any time. It is uncertain where an earthquake will strike, but there is a greater risk of an earthquake for areas lying on or near a fault. No one is ever prepared for an earthquake, so the people affected must face a sometimes terrifying reality and can be scarred for life. One country in particular that has been severely affected from an earthquake is Italy. Over a century ago Messina, a city located in Sicily, was to face one of the most devastating natural events of the century.
The Great Kanto Earthquake also known as the Tokyo-Yokohama Earthquake of 1923 hit the metropolitan area of Kanto on September 1st, 1923 around 11:58 pm. It was a 7.9 on the Richter magnitude scale, killing over one-hundred and forty thousand people due to its high magnitude and the time it happened. The earthquake struck around lunch time, when many Japanese people were at home cooking at their charcoal or gas fueled stoves. At the moment the earthquake hit, it knocked down buildings that caught flames from the stoves that fell over, enflaming the city. The fire was swept up and able to spread due to the gusts of wind that occurred for two days afterwards, resulting in firestorms. Charles Blauvelt experienced the ordeal of the fire describing the flames as “[covering] the whole city [as they] burned all day and night.” In addition to the firestorms and the earthquake itself, there was a shock because of all the fallen debris which triggered tsunamis to fill and flood Japanese cities. These tsunamis, that were about thirty feet tall, destroyed central Tokyo and immensely added to the death toll.
Tsunamis can go the same speed as a jetliner and that massive wave can out run the fastest runner. When there is a lot of waves at once, or the water goes back that is a sign that a tsunami is coming. If that tsunami is far then people need to get to the tallest and strongest building there is in the city that way they are safe and helicopter can pick them up. Tsunamis can wipe out an entire city or 1/4 of the country. Tsunamis can last up to an hour, or more.
The dangerousness of earthquakes are rated from one to ten. One being you aren’t able to feel it and ten being VERY powerful. There was a deadly earthquake, almost no one survived. A deadly 7.2 earthquake occurred in the Central Philippines. All signs and clues pointed to the East Bohol Fault. A 6 rated earthquake that happened before, injured 300 people and caused a tsunami. But the 7.2 earthquake didn’t cause any tsunami. All of the dangerous earthquakes damaged ports, schools and airports; even a hospital collapsed killing at least 18 people. Children were injured in stampedes at two sports complexes while others rushed to the exits. Five people were killed in a earthquake - triggered landslide. People respond to a natural disaster by gathering resources, spreading the word, and government help.
Additionally, this earthquake occurred on a thrust fault. This fault was a subduction zone slip which occurred primarily beneath the ocean were the Pacific plate plunges underneath the North American plate. This sudden upward movement of the sea floor along the rupturing fault generated a massive tsunami. This vertical deformation

An earthquake occurs abruptly and causes severs damage to people, property, landscape and more. A great mega-thrust earthquake, known as the Great Tohoku Earthquake has shaken Japan at 5:46:24 UTC on March 11, 2011. It caused a severe disaster, including tsunami and nuclear radiation exposure.. This mega-quake located at the latitude 38.297 degree North and longitude of 142.372 degree East, near the east coast of Honshu, Japan (USGS, 2013). An earthquake and tsunami waves caused widespread damage to many areas of Japan. People in Japan are still recovering from the damages.
Earthquakes are common in both California and Japan and sometimes these areas are hit by large magnitude earthquakes that cause vast destruction. This is the case for both the 1994 Northridge Earthquake and the 1995 Great Hanshin-Awaji Earthquake (also commonly referred to as the Kobe Earthquake). Although both earthquakes were around a 6.0 magnitude and happened exactly one year apart from each other, they had very different impacts in terms of infrastructure, disruption of economy, health issues, and secondary hazards.
Tsunamis are one of the most dangerous natural disasters known to mankind that cause devastating effects on society. Despite the fact that tsunamis are not frequent phenomena, it causes huge causalities once it occurs. The number of deaths could reach 420 thousand a year, accompanied by the destruction of many costal residences. But despite the fact that tsunami damages are inevitable, it can be reduced.
The death toll climbs to over 10,000 and is still rising (Branigan 2). The disaster in Japan began without warning on Friday March 11, 2011 at 2:46pm with a 9.0 magnitude earthquake, the strongest ever recorded in the country (Fackler 3). A massive thirty-three foot high tsunami, generated by the earthquake, swept over lands in northern Japan, taking objects and debris with it. To make matters worse, the tsunami caused the cooling systems at several nuclear power plants to fail. The disaster in Japan was a tragic event, and it had a plethora of causes and effects.
It was a beautiful day like any other with the clear blue sky and the
