U.s. Geological Survey Registered The Tohoku Earthquake

The most noticeable difference between a tsunami and a hurricane is the cause of each. A tsunami is the aftermath of an underwater earthquake or volcanic eruption. The force of the earthquake or eruption, along with the moving of the tectonic plates, sends large amounts of water in all directions. The waves can be thousands of feet high when they reach the shoreline. These giant waves can arrive at a moment's notice with no warning. The tsunami is a large natural phenomenon originating from the ocean, but it is not the only phenomenon to start in the ocean.

According to the research report, it will cause thousands of people die, towns submerged, buildings and bridges damaged once a huge earthquake and tsunamis happened on the Pacific Northwest area near American coast. And losses will be estimated at over 5 billion dollar US dollars. This shocking article was composed by seismic safety advisory committee in Oregon. According to materials, a super-strong earthquake once happened in A.D. 1700 Cascadia Subduction Zone (CSZ) on the Pacific Northwest coast. There are some experts forecast that another super-huge earthquake will occur in the future. The report has shown that once the earthquake occurs, the regions from North California to British Columbia Coastal region will suffer devastation, cause heavy casualties. Water and electricity shortage issues definitely follow this heavy disaster, meanwhile, communication and heating system and gas supply will definitely broken off in the light of this earthquake. The CSZ is a 1,000 km long dipping fault that stretches from Northern Vancouver Island to Cape Mendocino in northern California. It separates the Juan de Fuca (Juan

On March 11, 2011 an earthquake that measured 9.3 Richter scale occurred 43 miles of the coast of Northern Japan. This caused tremendous amounts of damage to the island of Tohouku. What happened is the quake initially destroyed buildings and property. However, a tsunami occurred, which devastated the region and the Fukushima nuclear power plant. ("Fukushima Accident")

Natural disasters are a huge challenge for the planet because of the adverse effects that are associated with them. One of the major earthquakes to have shaken the earth is the Great Sendai Earthquake or Great Tōhoku Earthquake that occurred in 2011. The event started when a powerful earthquake hit the northeastern Japan on March 11, 2011, and resulted in a widespread damage on land. A series of massive tsunamis later devastated many parts of the coastal regions of the country with the worst affected being the Tohoku region. The tsunami further resulted in a major nuclear accident that damaged distant regions on a power station located along the coast. The economic effects of the tsunami qualify it as one of the major natural disasters because it affected Japan’s economic stability as the country ended up resorting to importing as an alternative to cover the loss.

Throughout this unit, the Science in Practice class has been learning about natural disasters and the impact it has on humans and environment. The natural disaster that will be discussed in this report is the Boxing Day Tsunami, which occurred on the 26th of December, 2004. The tsunami took place in the Indian Ocean. Due to, two tectonics plates, the Indo-Australian plate and the Eurasian plate colliding, causing an underwater earthquake. Due to this awful disaster, people were killed, injured, diagnosed with diseases, homes and businesses were destroyed, the environment damaged.

Megathrust earthquakes are defined as interplate earthquakes caused by one tectonic plate being forced under another in a subduction zone. During the lifetime of a subduction zone, two plates are constantly moving towards each other, and due to the great amount of friction, these plates get “stuck” in various areas 2 (fig 1). Due to the build-up of stress in these areas, the plates eventually unlock and release a great amount of energy, resulting in a megathrust earthquake2.

Earthquakes are common environmental catastrophes which occur as a result of overwhelming stress being released within the earth. The location of the San Francisco Bay Area is extremely vulnerable to megathrust earthquakes

The tsunami waves reached heights up to 128 feet at Miyako city and traveled inland as far as six miles. A tsunami is a series of large sea waves caused by a large displacement of water. The tsunami flooded an estimated area of approximately 217 square miles in Japan. The massive waves destroyed large three-story buildings where many people seeked for safety. Within hours of the first tsunami hit Hawaii and set off multiple warning to Canada, Alaska, South America, the United States, the Oregon coast, and the Pacific.

Magnitude of the earthquake was 9.5 out of 10, with a rupture zone of about 1,000 km. About 1,655 people were killed, 3,000 wounded, 2 million homeless, and about $550 million lost in southern Chile. The volcano actually triggered a tsunami that killed 61 people and caused extensive damage in Hawaii, the Philippines, Easter Island, Samoa, and California. Residual damage caused landslides and volcanic eruptions after two days and lasted for several weeks. There were four foreshocks with magnitudes of seven or upper, five aftershocks with seven or upper levels, and some volcanoes. The first tremors and aftershocks began on May 21, 1960 and lasted until November 1, 2016.

Haiti, Japan, Taiwan...what do they all have in common? All 3 have had unexpected major earthquakes strike them and demolish there land. But what is an earthquake? An earthquake is the movement of earth’s tectonic plates. They happen because a mass energy causes the constantly moving tectonic plates to pass one another in either a transform, convergent or divergent movement, after a long period of time pushing against each other. They usually occur in cities located on the border of the tectonic plates like California, British Columbia (west coast) and Japan. Depending on the intensity of the earthquake, it has the potential to cause a lot of destruction and hurt many civilians. It can degrade community to a point where it would take years to recover. However much destruction has been caused, there are precautions that could be taken before hand to reduce the damage. This report will be comparing 3 major recent earthquakes from Haiti, Japan and Taiwan and how each country is doing post-earthquake.

All along the coast of Central America the tsunami was observed. (February 4, 1965, Alaska Earthquake, Rat Islands, Magnitude 8.7) This earthquake was recorded at a magnitude 8.7 and caused a big tsunami of over 10 m on Shemya Island. It barely caused any damage, though. Just two months after the initial shock, an aftershock earthquake at a magnitude of 7.6 hit the same area. (March 28, 2005, Sumatra Earthquake aka Nias Earthquake) Just off the coast of Sumatra, Indonesia, was a devastating earthquake that killed 1,300 people. A majority of the devastation occurred on the island of Nias. The massive earthquake sparked a panic around countries along the Indian Ocean because there was a massive tsunami just three months earlier in December. ( August 15, 1950, Assam, Tibet Earthquake, Magnitude 8.6) There were at least 780 people who died in this 8.6 magnitude earthquake. Many buildings completely collapsed in areas of Eastern Tibet. Landslides and ground cracks/fractures ended up washing away and entire village. The village of Yedong collapsed into the Yarlung Zangbo River and literally washed

According to the records of earthquake intensity, this is the strongest earthquake occurred in Japan and one of the most powerful earthquakes in the world ( ). When the Pacific land crashed down and the North American land slide up, the resulting of landslide and outburst of the bottom turn to create earthquake in the Pacific Ocean, and it was the biggest impact in 1200 years. Furthermore, the earthquake occurred from 130 kilometer east of the city of Honshu, Japan on March 11, 2011, and the main shock lasted for 40 minutes. The earthquake created magnitude scale to 9.0 Mw, and 165-foot movement occurred to the seafloor during the earthquake ( ). Moreover, at that time, most city of Japanese affected by that earthquake, and a nuclear power industry is one of the victims which was crashed by the earthquake. Because of that, it release of radiation to large area not only in Japan but also get oversea to another country such as China, Viet

In the last decade alone, there have been a number of natural disasters that have caused substantial physical damage and great emotional distress to the people who were affected. The aftermath of a natural disaster presents many concerns; communities become displaced, health risks and complications occur, food scarcity becomes a result of lost crops, and emotional aftershocks become apparent. Some Haitian’s have yet to recover from the earthquake they experienced in 2010. (Davis, 2015) “According to FEMA, the total damage for hurricane Katrina is estimated at $108 billion.” (CNN News, 2015), and 86,000 lives were taken in the earthquake of Pakistan in 2005 (EERI, 2006). In 2008, communities of Sichuan, China, endured a 7.9 magnitude earthquake that collapsed several buildings, killing over 87,000 people. Buildings had very poor infrastructures, which caused the destruction of many local schools. This contributed to the deaths of thousands of school aged children (BBC News, 2013). However, the Boxing Day tsunami was one of the largest and most destructive natural disasters of

On March 11th, 2011, the northern section of Japan was hit by a 9.0 magnitude earthquake, followed by a 15 meter tsunami, causing the death of over 15000 people. (Spacey) Even though the earthquake and the tsunami caused a tremendous amount of deaths in the northern region of Japan, the meltdown of the Fukushima nuclear power plant caused a severe damage to northern Japan’s ecosystem that people still cannot go back to their homes; despite it is 4 years after the disaster. After the earthquake, the tsunami destroyed the power supply used by Fukushima’s three nuclear power stations, causing severe levels of meltdown to be occurred inside the reactors in the timespan of 3 days. It was not until 2 weeks after the tragedy, when the reactors were finally stabilized, and took several months to approach what is called a “cold shutdown condition”, in which the fission in the reactors are completely stopped.(Fukushima A)

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.
