Long-Term Prediction: Long-term earthquake prediction recognizes that earthquakes have recurred many times along existing faults and will probably occur in these same regions again.
Short-Term Prediction: Short-term predictions are forecasts that an earthquake may occur at a specific place and time. Short-term prediction depends on signals that immediately precede an earthquake. Foreshocks are small earthquakes that precede a large quake by a few seconds to a few weeks.

The seismic Waves are divided in two types,body waves that travel throught the earth's surface like a hammer that hit the side.
Surface waves,that travel on earth's surface.
The body waves are divided in p-waves and s-waves.

 quakes have recurred many times along existing faults and 
 will probably occur in these same regions again. However, long-term prediction gives only a vague idea of when 
 the next earthquake will strike. Short-term predictions are forecasts that an earthquake may 
 occur at a specific place and time. Short-term prediction de- 
 pends on signals that immediately precede an earthquake. 
 Foreshocks are small earthquakes that precede a large 
 quake by a few seconds to a few weeks. The cause of fore- 
 shocks can be explained by a simple analogy. However, foreshocks 
 preceded only about half of a group of recent major earth- 
 quakes selected for study. In addition, some swarms of small 
 shocks thought to be foreshocks were not followed by a 
 large quake. Another approach to short-term earthquake prediction is 
 to measure changes in the land surface near an active fault 
 zone.

It can generate different kinds of seismic waves:
1: Body waves, which travel through the earth surface; they're divided in two different kinds:
a: Primary waves (P-waves, which are longitudinal waves);
b: S-waves, trasverser waves that move slowlier than P-waves.
2: surface waves, which travel on the top of the earth surface; they're divived in two kinds too:
a: Rolly waves, which move up and down;
b: Love waves (the most dangerous), which shift left and right and they're perpendicular to the direction of the motion]]> 2016-11-02 15:16:06 UTC https://padlet.com/vbalzarotti/2h3mg9rtuxa/wish/134810975 Arianna Fazio https://padlet.com/vbalzarotti/2h3mg9rtuxa/wish/134829752 Earthquake prediction is divided in long-term and short term prediction. Long term prediction gives only a vogue idea of when the next earthquake will strike. Short term prediction are forecast that on earthquake may occur at a specific place and time.
There are two types of seismic waves: surface waves and body waves. Surface waves, which travel through the earth surface, are divided in roll waves, which moving up and down the earth, and love waves, which moving left and right the earth.
Body waves travel on earth surface and there are two types of body waves: S-waves and P-waves.
S-waves are longitudinal. they can travel in air, solid and liquid. P-waves are transversal and they can only travel to solid.

There are two types of seismic waves: surface waves and body waves. Surface waves, which travel through the earth surface, are divided in roll waves, which moving up and down the earth, and love waves, which moving left and right the earth.
Body waves travel on earth surface and there are two types of body waves: S-waves and P-waves.
S-waves are longitudinal. they can travel in air, solid and liquid. P-waves are transversal and they can only travel to solid.
The epicenter is, instead, the point of the earth surface, located vertically above the hypocenter, which is reached first by the vibrations.
