They Can occur anywere a Fault Line is on Earth They happen when earths crust releases and the Fault Line send out Energy =p
Earthquakes and volcanoes both occur in land and ocean. =)
Yes, they are likely to occur.
Volcanoes
To release pressure.
Earthquakes and volcanoes occur mostly near the convergent plate boundary.
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.
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.
earthquakes occur because plates move and they over lap causing an earthquake.
Along fault lines
maybe
by killing people
Anywhere where the earths plates meet. Earthquakes occur only were there is an epicenter. Were ever the epicenter is the earthquake will happen.
