The ones that happen after are called aftershocks. It measured a 9. Sometimes the edges, which are called fault lines, can get stuck, but the plates keep moving.
The February earthquake in Christchurch, New Zealand followed nearly 6 months after a earthquake facts for homework 7. The rapid release of energy creates seismic waves that travel through the earth. Geologists estimate the fastest plate might shift 6 inches a year 15 centimeters. The plate tectonic theory is supported by heaps of evidence that takes into account the Earth's crust and upper mantle, which are made up of some large, thin, quite rigid plates that move relative to each other.
It measured a 9. The idea behind plate tectonics is an interesting story. Unfortunately scientists cannot predict earthquakes. You can actually feel earthquakes from quite some distance away, but surprisingly they normally last less than a minute. Earthquakes happen when a plate scrapes, bumps, or drags along another plate. The earthquake killed people and significantly damaged the central city.

These two waves travel along the surface of the Earth and cause the most damage during large earthquakes. Very few are felt.
There are the major types of faults called dip-slip normal, dip-slip reverse, strike-slip, and oblique-slip. Seismometers are used to measure the magnitude of earthquakes.
They can happen as deep as miles kilometers below the surface. Do you ever feel a bit stressed or worried about something? These plates slowly move over a long period of time.
We bet that minute feels like a lifetime. So now you should know all about earthquakes which can be extremely powerful and can cause a lot of damage too unfortunately. Large cracks in the earth. This is where broken rocks slide past each other, causing ford mustang essay crack in the Earth's surface. Activities Take a ten question quiz about this page.
These plates move in different directions and at different speeds too. You hold a stick horizontally. The earthquake that occurred in the Indian Ocean near Sumatra, Indonesia triggered a series of tsunamis that killed over people in 14 countries.
A very large earthquake will also produce Love waves and Rayleigh waves. About a half-million quakes rock earthquake facts for homework Earth every day.

Epicenters and Hypocenters The place where the earthquake starts, below the surface of the earth, is called the hypocenter. It happened inand measured 9. Using data from two other reporting stations they draw two more circles. Seismic wave chart of an earthquake Scientists use seismic waves to measure how big an earthquake is.
RING OF FIRE SCIENCE BOOKSTORE
Types of earthquake waves Every earthquake produces P waves and S waves. The earthquake is caused by stress building up in rocks until they break sending seismic waves in all directions.
Good engineering practises can help stop buildings collapsing under the stress of large earthquakes. The larger the number on the MMS scale, the larger the earthquake. Photograph by Naypong, Shutterstock The surface of the earthcalled the "crust," is not one solid piece.
This is where continents move from one place to the next and they break apart as the go, crashing and grinding against each other.
The earthquake killed people and significantly damaged the central city. That's millions a year.
Geologists cannot predict earthquakes. It was a magnitude 9.
Crustal plates moving apart, smashing together or slipping past each other horizontally cause an earthquake. It's more like a 20 piece puzzle. The earthquake that hit the Tohoku region of Japan on March 11,had a magnitude of 9.

It'll be neighbors with San Francisco in 15 million years. More Earthquakes Links Primary Waves Find out about primary waves which are the first earthquake waves to reach reporting stations.
This causes shock waves to shake the surface of the Earth in the form of an earthquake. Seismic Waves Shock waves from an earthquake that travel through the ground are called seismic waves.
The best they can do today is point out where fault lines are so we know where earthquakes are likely to occur. What is an earthquake? It is important in earthquake prone countries such as Japan to build houses and buildings that react well to earthquakes. An earthquake that hit Haiti in January with a magnitude of 7.
Earthquakes cause devastating destruction to buildings around the world.
That's because the shaking can cause windows to break, structures to collapse, fire, and other dangers. It would be teaching critical thinking focusing on metacognitive skills and problem solving to see a tsunami heading your way.

Enjoy our awesome range of Earth facts for kids. With normal waves, water flows in circles, but with a tsunami, water flows straight and this is why they can cause so much damage. Sometimes these plates crash together, pull apart or sideswipe each other. Fun Facts about Earthquakes The largest earthquake ever recorded in the world was in Chile in Most damage and deaths happen in populated areas.
Sometimes the edges, which are called fault lines, can get stuck, but the plates keep moving.
A tsunami is a large ocean wave which is normally caused by an earthquake that happens underwater or from a volcanic explosion. This is amazing; more than a million earthquakes rattle and shake the world every single year. Scientists use the different speeds of seismic waves to locate the epicentre the point on the surface directly above where the earthquake originated of earthquakes.
Check out the cool trivia and have fun learning about some of our planet's most amazing features. Where do earthquakes happen?
Seismologists use the difference in time that it takes the P wave and S waves to reach a reporting station to determine how far away the earthquake was when the rocks ruptured.
