Causes and Effects of Earthquakes There are some programs‚ like the ones that are broadcast at National Geographic Channel‚ where professionals show us on many opportunities documentaries about earthquakes and the amount of damage that they had produced in some areas. But… what is an earthquake? We can define them as the shaking of the Earth’s surface caused by the rapid movement of the Earth’s rocky outer layer. In addition‚ earthquakes results from two main factors and can have two harmful effects

Plate tectonics Intro: The word tectonic represents the meaning of plates and boundaries. As an example of activity is an earthquake‚ which is caused by two plates like the Eurasian and pacific plate pushing towards each other‚ pushing the land upwards causing a mountain as well as an earthquake. The plates are pieces of land that make up the outer crust‚ these could move together‚ move apart or move alongside each other resulting in mountains‚ volcanoes and earthquakes‚ this happens deep

First of all‚ Chile have many major active fault zones that are the root causes of earthquakes and other natural diaster. The Liquiñe-Ofqui Fault is major geological fault that runs a length of roughly 1000 km in a north-south direction and exhibits current seismicity. It is located in the Chilean Northern Patagonian Andes. It is a dextral intra-arc transform fault. When considered a fault zone‚ the Liquiñe-Ofqui Fault Zone (LOFZ) might include other neighboring faults such as Reigolil-Pirihueico

Why will the Alaskan Way Viaduct collapse? The Alaskan Way Viaduct will collapse because of an earthquake.The earthquake’s cause has to do with the layers of the Earth‚ mainly the lithosphere and the asthenosphere. The result of the lab “Density Column” proved that since the layers of the Earth are stacked on top of each other‚ like the liquids in the “Density Column”‚ the layers must have different densities. Another lab that was done in class‚ “Density Cubes”‚ showed that density‚ or

In the event that the development proceeds in light of current circumstances and course‚ in 10 million years‚ Los Angeles‚ presently at low scope‚ will have moved northward to the same scope as San Francisco. In 50 to 60 million years‚ Baja California and parts of California west of the San Andreas flaw will

Chapter 4 plate tectonics Need a Hint? 1.What evidence proved that South America‚ Africa‚ India‚ and Australia were once covered by glaciers? glacial deposits and rock surfaces scarred by glaciers 2. What happens when an oceanic plate converges with a continental plate? The denser oceanic plate slides under the less dense continental plate. 3. A divergent boundary is a boundary between two plates that __________. Move away from each other. 4.Do two colliding continental plates

The Assam Earthquake On August 15‚ 1897‚ more than 1538 people died. The cause was one of the biggest blind earthquakes in the world. This earthquake was at least an 8.1! Out of the earth‚ which was open for 5 days‚ came columns of steam and superheated liquid. Full villages fell into large cracks‚ dams broke and fields and towns flooded‚ forcing people into trees‚ where one woman gave birth. Put out your hand. Look at any one of your finger nails and watch it grow. This is what plate tectonics

Kobe Earthquake – Case Study Kobe Earthquake – Case Study In the early morning of January the 17th 1995 instruments in a lab in western Japan picked up a burst of intense electro-magnetic radiation. It was the signature of a massive earthquake which had just struck the City of Kobe from its epicentre 20 kilometres to the south west. There was no warning‚ 180‚000 buildings were destroyed‚ an urban area 20 kilometres long and 4 kilometres wide was totally wrecked. Nothing moved in or out of Kobe

Let’s play a game. Close your eyes and imagine that it’s the middle of the night and you are awaken by a loud roar coming beneath your feet. As you stumble downstairs you cover your head from objects falling from bedroom walls‚ kitchen cabinets‚ and bookshelves as you shout to your love ones to go outside. You head to the closet to get your emergency bag filled with two flashlights‚ three water bottles and six protein bars. As your about to exit the building it all stops just to be repeated a few

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
