The destructive effects of an earthquake can be classified into primary and secondary effects. Primary effects are the immediate damage caused by the quake‚ such as collapsing buildings‚ roads and bridges‚ which may kill many people. Those lucky enough to survive can suffer badly from shock and panic. Secondary effects are the after-effects of the earthquake‚ such as fires‚ tidal waves‚ landslides and disease. Fire - earthquakes destroy gas pipes and electric cables‚ causing fires to spread

Market Economy Definition Free Market Economy is an economy ruled by the people‚ not the government. It grants freedom to producers who now only have to make what is needed and wanted‚ not what the government decides is needed and wanted. And the buyers‚ producers‚ and sellers control prices‚ with almost no government interference. Characteristics of market economy In a Free Market Economy‚ the buyers‚ producers‚ and sellers control all prices‚ with very little government interference

The short answer is that earthquakes are caused by faulting‚ a sudden lateral or vertical movement of rock along a rupture (break) surface. Here’s the longer answer: The surface of the Earth is in continuous slow motion. This is plate tectonics--the motion of immense rigid plates at the surface of the Earth in response to flow of rock within the Earth. The plates cover the entire surface of the globe. Since they are all moving they rub against each other in some places (like the San Andreas

One of the strongest earthquakes in Mexico history struck the country’s southern coast. It happened later on a Thursday night. The earthquake destroyed hundreds of buildings. Panicked people ran into the streets in the middle of the night. About 90 people died. The earthquake hit minutes before midnight and caused buildings to sway violently in Mexico City. The capital of Mexico is more than 650 miles away from where the earthquake had struck. Beds were banging against walls. People still wearing

Essay on Earthquake The usual phenomena recorded in well-known earthquakes are first a trembling‚ next one or more serve shocks‚ and then a trembling which gradually dies away. In most cases‚ each shock lasts only a few seconds‚ but the trembling that follow may continue for days. Weeks or even months. Noises of various kinds usually accompany an earthquake. They have been likened to the growling of storm‚ the growling of thunder‚ the clanking and are not accompanied by these noises. At

Effects of earthquakes Shaking and ground rupture Shaking and ground rupture are the main effects created by earthquakes‚ principally resulting in more or less severe damage to buildings and other rigid structures. The severity of the local effects depends on the complex combination of the earthquake magnitude‚ the distance from the epicenter‚ and the local geological and geomorphological conditions‚ which may amplify or reduce wave propagation.[44] The ground-shaking is measured by ground acceleration

Relieving Chile and Haiti Many earthquakes strike different countries and very often‚ and they face efforts to rebuild the nation. Some countries do it better than others and some are more effective. But‚ this does not only apply to earthquakes but also to other natural disasters such as floods and droughts.

Pakistan Earthquake? On 8th October 2005‚ a devastating earthquake struck at the town of Muzaffarabad in Kashmir located in the country of Pakistan at about 8:50 am in the morning. It registered a moment magnitude of 7.6 on the Richter scale‚ affecting millions of people. Figures have shown that about 88‚710 people died‚ 106‚266 people were injured and up to three million became homeless and without proper shelter. There were many reasons why so many people died in the Pakistan Earthquake. One reason

Earthquakes are vibrations of earth caused by the rapid release of energy. These earthquakes can be caused by faults in the Earth’s crust scraping against each other. Faults are constantly sliding past each other‚ but can occasionally have difficulty when the earth around these faults cracks‚ causing the path to become rugged. When they don’t slide easily‚ they cause tension. When the tension and pressure is released‚ this causes said vibrations that can be large enough to damage and destroy cities

Course Title IEQ-05 : Earthquake Geology and Geoinformatics (Dept. of Earthquake Engineering‚ IIT Roorkee) What is an earthquake? An earthquake is the vibration of the earth produced by the quick release of energy. Most often‚ earthquakes are caused by movement along large fractures in the earth’s crust. Such fractures are called faults. The energy that is released radiates in all directions from its origin in the form of waves. These waves are similar to the waves that occur when you drop a
