It is not known how animals acted before the Kashmir earthquake hit. Animals do act differently before earthquakes hit. For example cats have been known to run away and act very strange a few days before a earthquake hits.
Before an earthquake nothing perceptible to humans happen. Several types of animals act up though. During a earthquake the ground trembles. Depending on the magnitude this might be anything from a light tremble to a violent shaking. Most of the time nothing happens after an earthquake, but sometimes there is an aftershock, which is another earthquake of a lesser magnitude.
The USGS publishes some excellent literature on earthquake risk.http://earthquake.usgs.gov/hazards/products/conterminous/2008/maps/If you look at the map, much of the west coast of California is at significant risk for earthquakes.However, also of note is a "hot spot" in the midwest. There is significant concern about this because of the predominance of older brick buildings and houses in cities like St. Louis that predate earthquake codes, and the soft soils that may act like jello and amplify the effects of the earthquake.
There are many factors to consider in this question and many types of bridge structure. The structure of a bridge is designed to resist the expected loads that will act on it. The main loads that usually act on a bridge are: - gravity (an acceleration downwards towards the centre of the Earth) on the bridge itself, - gravity on any objects on the bridge, - wind loads on the bridge ( can be in any direction but depends on exposure) - earthquake loads The loads experienced by the bridge in an earthquake can be as strong as or stronger than gravity (9.8ms-2), and act in many directions changing rapidly. A bridge designed to resist these therefore needs to have a structure that can resist significant forces in many directions, (to picture these forces it may help to imagine a model of the bridge being tossed from hand to hand, twisted and shaken), or it can be isolated from the earthquake forces by allowing the earth to move up down and around while the bridge sits quietly. If we look at the example of a simple suspension bridge for one person to walk over, made from some steel cables and wire mesh: - it is light and will not need to resist huge forces (Force= mass.acceleration), - it has the advantage of the elasticity of the steel, - it has the disadvantage that if it is not under much tension ( ie. has slack cables), these may be snapped rapidly in different directions in an earthquake, (picture a whip being used) which will put big loads on them.
Base-isolated buildings using rubber or steel pads minimize earthquake damage to buildings by absorbing the energy from seismic waves. They act much like car shock suspension, which absorb energy while keeping car occupants and the car base steady.
why ARE large earthquakes.... ANSWER- Aftershocks happen after a big earthquake because the movement on the fault changed the forces in the earth that act on the fault itself and nearby. Aftershocks go on until the fault recovers, which takes much longer in the middle of a continent.

Pets and animals will start to act crazy about 10-30 seconds before an earthquake hits. This is because they have better hearing and they can hear P waves or primary waves coming. A P wave is a very fast wave that can go through solids, gases, and liquids. So just before an earthquake, the Primary Waves are coming.
dogs and many other animals have strange behaviors before an earthquake/tsunami because they can sense them. dogs bark, and birds fly away. just because your dog is barking at nothing however, it doesn't mean there's an earthquake.
Well there are warnings if there are earthquakes coming but not by humans by animals. Animals have very sharp senses, so if there was danger your animals will act crazy so you should keep an eye on your animals. Also i recommend you to have a pet. (NOT A LAZY ONE!)
Well, technically speaking, many animals act weird when a natural disaster is about to strike. Such as cats and dogs.
Act of nature.
quanflication
The Act requires that before being slaughtered, animals must be rendered unconscious by mechanical, electrical, or chemical means
Because the fault line will act up and that is a warning sign of a earthquake.
Jammu and Kashmir,one of the most beautiful states of India, is also the fulcrum of issues marring India's peace drive.And because of this controversial side of J&K and also because of the living conditions there aren't the same compared to the rest of India, it doesn't fall in the purview of the Consumer Protection Legislation.But as we know, rules are substratum for harmonious living, another act that is Jammu & Kashmir Consumer Protection Act 1987 was introduced.
Earthquake hazard reduction act
they should be calm
