The topic of my presentation it is about earthquakes and how these affect the whole world and especially how these affect in Chile.
I choose this topic because I found a really interesting and serves me as a student of geography, to understand the dynamics of earthquakes.
In the presentation I am going to speak about earthquakes formation and earthquakes in Chile in the whole detected history.
Also I will talk about how we can prevent certain risks that may occur before or after an earthquake.
Earthquakes 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. Most earthquakes occur at fault zones, where tectonic plates collide or slide against each other. These impacts are usually gradual.
Scientists assign a magnitude rating to earthquakes based on the strength and duration of their seismic waves.
On average, a magnitude 8 quake strikes somewhere every year and many people die in earthquakes annually. Collapsing buildings claim by far the majority of lives, but the destruction is often compounded by mud slides, fires, floods, or tsunamis.
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.
