Because of it's location directly on what vulcanologist call the "Pacific ring of fire", a high volcanism and earthquake area.
Earthquakes and volcanoes most commonly occur at tectonic plate boundaries called fault lines.The US Geological suvey has quite a nice website entitled "This Dynamic Earth" which will probably answer any more specific questions.http://pubs.usgs.gov/gip/dynamic/dynamic.html
Earthquakes and volcanoes both occur in land and ocean. =)
Yes, they are likely to occur.
Most earthquakes occur on plate boundaries such as Japan and Chile and most volcanoes occur in diverging plate boundaries like Dallol and Iceland and the Pacific Ring of Fire like Ecuador and Indonesia
Underground Earthquakes occur along fault lines. Volcanoes are all over the world but a good place to find one is in the Ring of Fire.
Volcanoes
To release pressure.
Because, over 1000 earthquakes may occur within a year, over 160 volcanoes are still active, tidal waves can occur after earthquakes, and then typhoons are a possibility on the islands.
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.
