Spring-pendulum seismometers were used before electronics were able to measure the size of earthquakes.
Tectonic earthquakes occur anywhere in the earth where there is sufficient stored elastic strain energy to drive fracture propagation along a fault plane.
It is estimated that only 10 percent or less of an earthquake’s total energy is radiated as seismic energy.
While most earthquakes are caused by movement of the Earth’s tectonic plates, human activity can also produce earthquakes.
In geology, a fault is a planar fracture or discontinuity in a volume of rock, across which there has been significant displacement. There is a common myth (particularly in New Zealand where earthquakes are common) that if you have a lot of small earthquakes, it helps to alleviate the pressures building up that can cause a big one. The people living in northern hemisphere are more likely to face earthquake than those living in southern hemisphere. An earthquake can cause landslide.  The worst one occurred in Kandu Province, China in 1920. Hurricane Katrina facts present the sad facts about one of the biggest disasters in the American history.
Natural Disaster Facts elaborate the information about the disaster occurred on earth caused by the harsh nature. Earthquakes, also called temblors, can be so tremendously destructive, it’s hard to imagine they occur by the thousands every day around the world, usually in the form of small tremors.Some 80 percent of all the planet's earthquakes occur along the rim of the Pacific Ocean, called the "Ring of Fire" because of the preponderance of volcanic activity there as well. Catch a glimpse of wildfires from a rare perspective, as firefighters open a window into their world. Unlike earthquakes, which are often followed by aftershocks, the storms that birth tornadoes are independent of one another.

See how you measure up against others, and how changes at home could do tons to protect the planet. The National Geographic Society aims to be an international leader for global conservation and environmental sustainability. Seismologists can tell how serious an earthquake is by a machine called a seismograph, which rates the intensity of the quake’s shaking. Seismologists can tell how serious an earthquake is by a machine called a seismogram, which rates the intensity of the quake’s shaking. Answer: If you’re in a building in an earthquake, get under a table or desk and hold onto it.
So far, earthquake prediction is highly controversial as there is little or mutually acceptable evidence to link observable phenomena to subsequent seismicity. There are several school of thoughts on the earthquake prediction, notable among is Jim Berkland, a retired geologist from USGS, who, according to his supporters, has 80% accuracy rates. India's high earthquake risk and vulnerability is evident from the fact that about 59 per cent of India's land area could face moderate to severe earthquakes.


The building collapse results in the widespread loss of lives and property including lifeline infrastructure like roads, dams and bridges, hospitals as well as public utilities like power and water supply installations.
India has advanced considerably in developing earthquake resistant codes of practice and guidelines for constructing RCC and steel framed buildings, brick or stone masonry buildings and combination of clay, wood, bamboo and thatched houses. During the International Decade for Natural Disaster Reduction (IDNDR) observed by the United Nations (UN) in the 1990s, India witnessed several earthquakes like the Uttarkashi earthquake of 1991, the Latur earthquake of 1993, the Jabalpur earthquake of 1997, and the Chamoli earthquake of 1999.
Hurricane Sandy facts give you the detail information about the disaster which made people die and damage many buildings.
Avalanches facts provide the information about the disaster that can occur each year in the snowy region. A medium-sized spring-pendulum seismometer, about three stories tall, is located in Mexico City, Mexico and is still in use.
In the case of transform or convergent type plate boundaries, which form the largest fault surfaces on earth, they move past each other smoothly and aseismically only if there are no irregularities  along the boundary that increase the frictional resistance.
Most of the earthquake’s energy is used to power the earthquake fracture growth or is converted into heat generated by friction. Four main activities contribute to this phenomenon: constructing large dams and buildings, drilling and injecting liquid into wells, and by coal mining and oil drilling. However this would be a dangerous pursuit in any populated area, as one might trigger a damaging earthquake. It was used in 1970 to replace the old measurement of Richter scale used by the people since 1930s. It is believed that the planet is hold by 8 elephants placed by the turtle back and sit on the coiled of snake.
Most earthquakes occur at fault zones, where tectonic plates—giant rock slabs that make up the Earth's upper layer—collide or slide against each other. When individuals pledge to use less water in their own lives, our partners carry out restoration work in the Colorado River Basin. Other western states, like Nevada, Idaho, Washington and Oregon are prone to earthquakes or can be damaged by earthquakes that happen in Alaska and California.

The frequent practice of publishing predictions after the fact further complicates matters.
During the period 1990 to 2006, more than 23,000 lives were lost due to 6 major earthquakes in India, which also caused enormous damage to property and public infrastructure. Yet high level of earthquake risk in our country?s context is mostly attributed to the unplanned and ill planned urban infrastructures developments. Some of the photographs of Indian earthquakes are available here Click hereThese were followed by the Bhuj earthquake of 26 January 2001 and the Jammu & Kashmir earthquake of 8 October 2005. It represents a risk to many countries of the world, particularly western North and South America, Japan, China, the Phillipines, New Zealand, northern part of India and the middle east region. Energy release associated with rapid movement on active faults is the cause of most earthquakes. The energy released from the earthquake is equal with energy used by the US people for three days to power the business and home.


These impacts are usually gradual and unnoticeable on the surface; however, immense stress can build up between plates. Over 80 percent of the earth’s earthquakes happen in the Pacific Ocean, in a place known as the “Ring of Fire.” Annually, around 10,000 people die in earthquakes every year. Sometimes they slide under one another or push up against each other, creating enormous stress. Also, given enough predictions, it is virtually inevitable that some will succeed "by chance." Assessing whether a successful prediction is a fluke is challenging. The occurrence of several devastating earthquakes in areas hitherto considered safe from earthquakes indicates that the built environment in the country is extremely fragile and our ability to prepare ourselves and effectively respond to earthquakes is inadequate. In order to reduce vulnerability it is important to create proper awareness about earthquake induced damages and their mitigation measures.
All these major earthquakes established that the casualties were caused primarily due to the collapse of buildings. A comprehensive details of earthquake as a science and understanding of various facts that lead to enormous damages and destructions are available here Click here. Almost every year we hear together how this planet moves, shaking up, shifting and killed thousand of lives on top of it. The Zipingpu Dam is believed to have fluctuated the pressure of the fault 503 meters away; this pressure probably increased the power of the earthquake and accelerated the rate of movement for the fault. A fault line is the surface trace of a fault, the line of intersection between the fault plane and the Earth’s surface.
When this stress is released quickly, it sends massive vibrations, called seismic waves, often hundreds of miles through the rock and up to the surface.
Alaska is followed by California, Hawaii, Nevada, Washington, Idaho, Wyoming, Montana and Utah. Most assessments rely on chance models for earthquake occurrence, models that are difficult to test or validate, because large earthquakes are so rare, and because earthquake activity is naturally clustered in space and time. However, similar high intensity earthquakes in the United States, Japan, etc., do not lead to such enormous loss of lives, as the structures in these countries are built with structural mitigation measures and earthquake-resistant features.
The greatest earthquake in Australia’s history is also claimed to be induced by humanity, through coal mining.
Other quakes can occur far from faults zones when plates are stretched or squeezed.Scientists assign a magnitude rating to earthquakes based on the strength and duration of their seismic waves. Some earthquake collaborate with Tsunami and that makes his killing score rise up to hundreds of thousands lives.
The earthquake has been reported to be spawned from a fault that reactivated due to the millions of tonnes of rock removed in the mining process. Collapsing buildings claim by far the majority of lives, but the destruction is often compounded by mud slides, fires, floods, or tsunamis. Smaller temblors that usually occur in the days following a large earthquake can complicate rescue efforts and cause further death and destruction.Loss of life can be avoided through emergency planning, education, and the construction of buildings that sway rather than break under the stress of an earthquake.
