The science of earthquakes is not there yet as to be able to predict earthquakes accurately.
It is an highly inaccurate science.
We can however use statistics, and this, although not timewise accurate, can predict earthquakes at different locations.
All over the world there are approx 25.000 earthquakes of various magnitude every year.
With increased tension in the zones where continental drift causes the different plates to collide, the risk of earthquakes increases. This tension builds up until it reaches a critical level. When the tension is critical, then even pretty small energydischarges can release the tension and we have an earthquake. There are many factors as to when the tension becomes critical and we can not measure this, only anticipate.
Italy is prone to many earthquakes ranging from 4.0 magnitude to 6.0, however, there have been quakes measuring 7.0 or more. The 1908 Messina earthquake is believed to have been a 7.2.
Before the 2009 event, the last major event in Italy was the 2002 M5.9 Molise earthquake, that killed 28 people.
Because of tectonic plates moving tomowards each other
There are earthquakes, tornadoes, volcanic eruptions, mud slides, and heavy rains in Italy.
Tectonic Plate boundaries.
The answer is that earthquakes and volcanoes are most frequent along Tectonic plate boundaries, these are the natural pieces that the continents and oceans are on.
They will happen around the edges of tectonic plates.
They are most likely to occur at transform boundaries.
Near to subduction zones where stresses in the subducting crustal plate can cause earthquakes with very deep hypocentres.
Australia
earthquakes are most likely to occur on the rim of tectonic plates
alpine system
If you mean "where" earthquakes and volcanoes are most likely to occur it is in what's called the "ring of fire" which is the coastal ring around the Pacific Ocean.
along fault lines
The answer is Earthquakes
Tectonic Plate boundaries.
On plate boundaries .
The answer is Earthquakes
The answer is that earthquakes and volcanoes are most frequent along Tectonic plate boundaries, these are the natural pieces that the continents and oceans are on.
Most earthquakes do occur on fault lines.
They will happen around the edges of tectonic plates.
