What Are Earthquakes?

Earthquakes are movements created by plates that can cause a lot of destruction. These can be recorded by seismographs

What Creates Earthquakes?

Transform boundaries causes earthquakes as well. but its not as effective as a convergent boundaries. also volcano activity causes earthquakes

Another way is convergent boundaries. These crush, split and create subduction , which one plate, or pretty much land, that goes underneath the other plate

How Earthquakes Are Formed

melissark1113 — 2015-03-24 18:12:54 UTC

this video shows a brief description using diagrams and pictures of how theyre formed

Diagram

In this illustration it shows what happens when the lithosphere, or the earth crust is affected before and after an earthquake. In the illustration

Seismographs

you were wondering what these were? Well, these devices use little waves to indicate how strong an earthquake is. the little knob swings left and right making the waves

Subduction Boundaries

melissark1113 — 2015-03-24 19:12:06 UTC

in this picture, it's showing an example of a subduction boundary

Transform Boundaries

melissark1113 — 2015-03-24 19:14:27 UTC

in a way, transverse boundaries can be convergent ones, as well. they have in contact whe they rub against each other and create vibrations- AKA the earthquake

What happens

melissark1113 — 2015-03-24 19:19:02 UTC

when the plates interact with eachother, it creates P waves, which are pressure waves. these go through the earth's fault line and KABOOM! the earthquake is formed

Subduction

melissark1113 — 2015-03-24 19:22:26 UTC

These can create some deadly earthquakes. In the picture, it shows when one plate slides underneath, it creates vibrations- hard ones

Earthquakes and Tsunamis

melissark1113 — 2015-03-24 19:30:06 UTC

Sometimes when they get really extreme they create Tsunamis

Epicenters. What Are They?

melissark1113 — 2015-03-26 19:25:47 UTC

Epicenter is when the point of the earth surface is above the focus of an earthquake.

Volanoes

melissark1113 — 2015-03-31 17:47:25 UTC

What does this have to do with eathquakes? Volcanoes an be an impact to forming an earthquake. When volcanoes errupt, it creates a vibration on the ground

Other additional facts

melissark1113 — 2015-03-31 17:54:29 UTC

With the convergent boundaries colliding, it can crack and pop making the pwaves very strong

How are they made?

melissark1113 — 2015-03-31 18:22:45 UTC

There are three types of fault lines:

Normal (pic 2)

Reverse (thurst) (pic 3)

Slip strike (pic 1)

There is also another one called a blind thrust. these ones create a little earthquake. its really weak.
