Yes, they are likely to occur.
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.
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.
The majority of earth's volcanoes and earthquakes occur near the boundaries of tectonic plates. Therefore, an area that has volcanoes is likely to be prone to earthquake as well.
Earthquakes and volcanoes both occur in land and ocean. =)

Earthquakes and volcanoes occur mostly near the convergent plate boundary.
earthquakes occur because plates move and they over lap causing an earthquake.
Along fault lines
