Introduction: The earth’s crust is made up of pieces of rock called plate tectonics that are always moving. Slowly sliding around‚ sliding past one another and bumping into each other. This constant movement causes pressure to build up between two plates‚ until it suddenly breaks were the plates meet. This is called a fault line. When the rock breaks energy is released in seismic waves that radiate from where the earthquake starts‚ a place called the focus. These Seismic waves are what cause the

Earthquakes Geography project Done by: DESHER TROTMAN Introduction Definition: An earthquake is a sudden tremor or movement of the earth’s crust‚ which originates naturally at or below the Earth’s surface. They can occur from fault lines where tectonic plates meet or from volcanic activity. Earthquakes are very common in areas of volcanic activity where they either proceed or accompany eruptions. Earthquakes caused by volcanic eruptions are rare since all volcanoes are not prone to violent

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. In such situations‚ humanitarian and development aid rush in from different corners of the world and from the countries government. The aid that is received goes into the relief efforts of the

powerful earthquake in half a century. The 7.9 magnitude earthquake killed as many as 2‚000‚ injured at least 2‚000‚ and left 4‚000 missing. Most of the missing are thought to be buried under rubble‚ and rescue workers dug frantically with bulldozers‚ shovels‚ sticks -- even bare hands -- trying to find them. India’s Earthquake -- Residents in the Gujarat State of western India spent the night outside Friday‚ too fearful to go back into their damaged homes after India’s most powerful earthquake in half

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

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

Earthquake Drill Platoon 3 - Jacinto Objectives The objectives of the earthquake drill are: • To ensure the safety of a student‚ parent‚ teachers and staff during and after an earthquake • To train the school community on life saving skills. • To give hands on experience on the earthquake and fire safety through mock drills. • To spread the culture of disaster preparedness. Before the Drill • • • • Every one should be mentally prepared. Participate well. Knows the basic

Would earthquakes of similar magnitudes in different populated regions of the Earth cause approximately the same levels of damage? In your discussions‚ consider both geologic and human-induced factors. The amount of damage caused by an Earthquake does not solely depend on the magnitude of the Earthquake. Factors such as population‚ geographic location‚ soil type‚ and the type of building material commonly used for construction in a region determine the extent of damage caused. If an Earthquake strikes

Examples of natural hazards are: earthquakes‚ tsunamis‚ wildfires‚ floods‚ volcanic eruptions etc. Earthquakes and their Occurence What is an Earthquake? An earthquake is a sudden rapid vibration along the earth’s crust due to individual tremors‚ sometimes causing great destruction to the earth’s lithosphere and its inhabitants. Earthquakes occur both on land and sea.They may occur at areas where plates collide (subduction zones/ convergent
