An earthquake is a major natural disaster which damages a lot of life and property as well as interrupts the socio economic growth of a particular geographic region. It causes shaking and ground rupture, landslides, avalanches, tsunami, soil liquefaction, floods, fires, etc. Both wildlife and human beings experience huge loss to their life and livelihood through earthquakes.
Some deadliest earthquakes till the date;
• 1556 Shaanxi earthquake: On 23rd January, 1556 at Shaanxi (China) world’s worst quake took around 8 lakh lives with its 8.0Mw (Magnitude) vibration. More than 500 miles area damaged through it.
• Great Tangshan earthquake: On1976 July 28, China again experienced another horrific natural disaster of 7.7Mw shake which destroyed a lot of hard earned properties and around 7 lakh innocent lives.
• 2004 Indian Ocean earthquake and tsunami: It was a historic and terrible mishap in India and 13 other countries. Around 3 lakh people lost their life and the tsunami caused by this accident was a threat to the whole world.
Disaster management and safety tips for Earthquakes:
The process of dealing with and avoiding the risks or hazards resulted through a disaster is defined as disaster management. Disaster management for earthquake is a continuing process. It starts with the warning and continues until the living victims becomes independent to carry-on their livelihood. Support from different levels like individuals, corporate houses (CSR), NGOs, Government disaster management cell or other philanthropic organizations helps a lot in reconstructing the society.

...nto the damaged building instantly after the quake as the damaged or loosen parts of the concretes may fall down on you.
3. If you think your building is safe after the quake then check the electricity connection as well as the LPG pipe before using them. Also the water pipes may cause accidents.
4. Help other injured people and offer food, water or first-aid. Ask support from others in evacuating the injured people or distributing relief stuffs. Stress more on the infants, disable and old persons.
5. Inform the disaster management authorities about missing of your family member if you are finding them. Be calm if unfortunately one of your family members seriously injured or died during the mishap.
Following the disaster management and safety techniques for earthquakes or any other critical natural disasters requires robust environment resource management planning.
...nd others for injuries, look for and extinguish small fires, inspect your home for damage, listen to the radio for instructions, and expect aftershocks.
Earthquakes happen about 20,000 times a year worldwide. They can destroy almost anything.In 2011, Japan had 9.1 magnitude earthquake, close to the highest magnitude of 9.2 in Alaska. They suffered tremendous damage from such a strong earthquake. The year before Haiti suffered from a 7.0 magnitude earthquake, still quite high compared to small tremors at magnitude 0-2. Japan recovered and rebuilt much faster than haiti did though. Haiti isn't even quite done recovering yet. The earthquakes had such different effects on the countries because of their economy, the condition of their people, and population rates.
The 1906 San Francisco earthquake was one of the largest earthquakes in the United States. Even though it only lasted less than a minute, the damages and aftermath of the earthquake were disastrous. These damages were not just from the earthquake, but also from other hazards that occurred because of it. It also had a huge effect on the people living in San Francisco. Many people, the government, and other countries helped the city of San Francisco with relief goods like food and clothing. The city used up their resources in order to rebuild the city and spent a lot of money. This earthquake also started a scientific revolution about earthquakes and its effects.
D.J. Dowrick (”Earthquake Risk Reduction”in Wiley) explains that seismic hazard is any physical phenomenon associated with an earthquake that may produce adverse effects on human activities. Earthquakes occur very suddenly without any warning. Thus, earthquake not only destructs people’s living environment, but also affects people’s mental health. People are more scared of earthquake. In 2010, there are two severe earthquakes, which are Haiti Earthquake and Chile Earthquake. Both of these two earthquakes produced the various impact considerably across countries and regions. The purpose of this essay is to analyse those two earthquakes according to knowledge such as why they occur, how strong they are, and what the impact they made. Even though people still can not predict earthquake, through analyse earthquakes, they can prevent it bring huge losses.
Debris from the Earthquake falls into the ponds,lakes, and rivers. The spilling of hazardous chemicals makes its way to the water supply as well. This kills wildlife that live in the water system, as well as the ones that use it for water or their food supply.
Hazards pose risk to everyone. Our acceptance of the risks associated with hazards dictates where and how we live. As humans, we accept a certain amount of risk when choosing to live our daily lives. From time to time, a hazard becomes an emergent situation. Tornadoes in the Midwest, hurricanes along the Gulf Coast or earthquakes in California are all hazards that residents in those regions accept and live with. This paper will examine one hazard that caused a disaster requiring a response from emergency management personnel. Specifically, the hazard more closely examined here is an earthquake. With the recent twenty year anniversary covered by many media outlets, the January 17, 1994, Northridge, California earthquake to date is the most expensive earthquake in American history.

Unfortunately, as the San Francisco Chronicle in 2006 reported that “there are still thousands of hostility rebuilt, unreinforced masonry buildings” that are build very close together with no fire resistance walls in between (John Galvin, 2007). Plus, the Association of Bay Area Governments stated that if a magnitude 7 and above earthquake a long the San Andreas Fault by San Francisco will affect the homes of many thousands of people forcing them to live in the streets once again (John Galvin, 2008). In the other hand, according to John Galvin article San Francisco’s water delivery system was improved and even though insurance companies loss a lot of money they paid out millions in claims.
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.
Earthquakes can be very dangerous but what matters the most is that everybody is safe, and that we need to work together. One earthquake, in the Philippines, was truly devastating. It was classified as a 7.2 magnitude. The Philippines responded very well by gathering their resources, spreading the word, and giving donations. They bounced back very quickly.
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.
Authorities have attempted to implement codes or regulations, but that has proved to be very difficult tasks becasue there are many variables that effect the dynamic response of buildings. One way to try to avoid disaster is to evaluate seismic risk is to look at a buildings hazards, exposure, vulnerability, and location. Hazards are, for example, landslides ad soil type. Exposure is a building's occupancy and function. Vulnerability is the expected performance of a building's system, and location is how often earthquakes occur in the area. (Lagorio)
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.
The increase in unpredictable natural disasters events for a decade has led to put the disaster preparedness as a central issue in disaster management. Disaster preparedness reduces the risk of loss lives and injuries and increases a capacity for coping when hazard occurs. Considering the value of the preparatory behavior, governments, local, national and international institutions and non-government organizations made some efforts in promoting disaster preparedness. However, although a number of resources have been expended in an effort to promote behavioural preparedness, a common finding in research on natural disaster is that people fail to take preparation for such disaster events (Paton, 2005; Shaw 2004; Spittal, et.al, 2005; Tierney, 1993; Kenny, 2009; Kapucu, 2008; Coppola and Maloney, 2009). For example, the fact that nearly 91% of Americans live in a moderate to high risk of natural disasters, only 16% take a preparation for natural disaster (Ripley, 2006).
Earthquakes belong to the class of most disastrous natural hazards. They result in unexpected and tremendous earth movements. These movements results from dissemination of an enormous amount of intense energy in form of seismic waves which are detected by use of seismograms. The impact of earthquakes leaves behind several landmarks including: destruction of property, extensive disruption of services like sewer and water lines, loss of life, and causes instability in both economic and social components of the affected nation (Webcache 2).
