Have you ever assured someone that your friend is reliable by saying that he or she "has both feet on the ground"? The fact that such a phrase exists shows how much comfort we take in the idea that the ground beneath our feet is unmoving, unchanging and dependable. Indeed, much of our civilization, from our houses and buildings to our energy, food and water sources, depends on unmoving earth. In truth, however, our planet's seemingly stable surface is made up of enormous pieces of rock that are slowly but constantly moving. Those pieces continually collide with and rub against one another, and sometimes their edges abruptly crack or slip and suddenly release huge amounts of pent-up energy. These unsettling events are called earthquakes, and small ones happen across the planet every day, without people even noticing. But every so often, a big earthquake occurs, and when that happens, the pulses of energy it releases, called seismic waves, can wreak almost unfathomable destruction and kill and injure many thousands of people [source: Bolt]. That sort of cataclysm occurred on March 11, 2011, in Japan, when a massive quake, later estimated by Japanese Meteorological Agency to be 9.0 in magnitude, struck 81 miles (130 kilometers) east of the city of Sendai on the nation's northeastern coast. The forces of the quake, the fifth most powerful in the past century, set off a giant wave, called a tsunami, that engulfed villages, destroyed buildings and drowned and crushed people who lived there [source: Green]. The earthquake and tsunami also badly damaged a six-reactor nuclear power plant in Fukushima, 150 miles (241 kilometers) north of Tokyo, destroying the backup generators that powered its cooling systems and causing a dangerous release of radiation that forced people in the region to flee. In all, the quake claimed the lives of 20,896 people, according to the U.S. Geological Survey. Though earthquakes have terrorized people since ancient times, it's only been in the past 100 years that scientists have come to understand what causes them, and to develop technology to detect their origin and measure their magnitude. In addition, engineers and architects have worked to make buildings more resistant to earthquake shocks. Someday, researchers hope to find a way to predict earthquakes in advance, and perhaps even control them. In this article, we'll give you the latest scientific knowledge about earthquakes, and discuss how humans can cope with them. But first, here are some basic earthquake facts. http://science.howstuffworks.com/nature/natural-disasters/earthquake.htm
A sudden movement of the earth's crust caused by the release of stress accumulated along geologic faults or by volcanic activity. Also called seism, temblor.

An earthquake is what happens when two blocks of the earth suddenly slip past one another. The surface where they slip is called the fault or fault plane. The location below the earth’s surface where the earthquake starts is called the hypocenter, and the location directly above it on the surface of the earth is called the epicenter.
Sometimes an earthquake has foreshocks. These are smaller earthquakes that happen in the same place as the larger earthquake that follows. Scientists can’t tell that an earthquake is a foreshock until the larger earthquake happens. The largest, main earthquake is called the mainshock. Mainshocks always have aftershocks that follow. These are smaller earthquakes that occur afterwards in the same place as the mainshock. Depending on the size of the mainshock, aftershocks can continue for weeks, months, and even years after the mainshock!
An Earthquake is the vibration when the rock's buildup energy. To relive the pressure or energy they stretch, bend, and may even break. The Earth will then split the Earth.
An earthquake is caused by a sudden slip on a fault. The tectonic plates are always slowly moving, but they get stuck at their edges due to friction. When the stress on the edge overcomes the friction, there is an earthquake that releases energy in waves that travel through the earth's crust and cause the shaking that we feel.

An earthquake is a natural disaster caused by Earth that makes the ground shake. Earthquakes happen when 2 of earth's plates grind against each other or are caused by volcanic action.

An earthquake is when the tectonic plates in earth shift from to much energy stored up in the rock much like a elastic rubber band snapping from to much pressure applied to a rock.

A earthquake is a movement of earths plates.The shaking we feel is caused by the plates violently scraping the others.The experience we get is very scary!

when the earth shakes because plates hit eachother
An earthquake is when the plates underground rub together.
Its movements within earth's crust , or volcanic action

When earths plates move hit each other thats what a earthquakes are.
a sudden and violent shaking of the ground, sometimes causing great destruction, as a result of movements within the earth's crust or volcanic action.
Its when the plates grind together and they make the earth shake.

how does pizza steve relate to the question ?

An earthquake is a sudden shaking of the earth created by two plates that( lye within the earth )rub together and make an earthquake.
when to plate rub it make the ground shake
!
Its when the ground shakes and creates the disaster
An earthquake is when the plates underground rub together.
when 2 plates under ground rub it makes the ground shake !
