Where would one find most of the volcanoes and earthquake zones in the world and why?

Where can we find volcanoes on earth?

Most volcanoes are found near subduction zones and mid-ocean ridges. This explains why the map of volcanoes on Earth matches so well the map of tectonic plates. On the other hand, some volcanoes are located in remote places like in the middle of the Pacific plate (Hawaii), thousands of kilometres away from the nearest plate boundary. This kind of volcano is very special: it is the consequence of a hotspot.

A hotspot is a mantle plume, seemingly coming from the outer core of our planet. It is a flow of hot and less dense material that crosses the solid mantle and breaks through the crust. This process creates intense and very localised volcanism at the surface. As the tectonic plates are continuously moving, hotspots leave a series of volcanic mounts at the surface of the Earth. A good example is the Hawaiian-Emperor seamount chain, a chain of ancient volcanoes created by the hotspot currently below Hawaii, which stretches over 5800km from Hawaii to Russia.
 

Where do earthquakes occur?

Earthquakes can strike any location at any time. But history shows they occur in the same general patterns year after year, principally in three large zones of the earth. The world's greatest earthquake belt, the circum-Pacific seismic belt, is found along the rim of the Pacific Ocean, where about 81 percent of the world's largest earthquakes occur. It has earned the nickname "Ring of Fire". The belt extends from Chile, northward along the South American coast through Central America, Mexico, the West Coast of the United States, and the southern part of Alaska, through the Aleutian Islands to Japan, the Philippine Islands, New Guinea, the island groups of the Southwest Pacific, and to New Zealand.

The second important belt, the Alpide, extends from Java to Sumatra through the Himalayas, the Mediterranean, and out into the Atlantic. This belt accounts for about 17 percent of the world's largest earthquakes, including some of the most destructive, such as the Iran shock that took 11,000 lives in August 1968, and the Turkey tremors in March 1970 and May 1971 that each killed over 1,000. All were near magnitude 7.

The third prominent belt follows the submerged 
mid-Atlantic Ridge.The remaining shocks are scattered in various areas of the world. Earthquakes in these prominent seismic zones are taken for granted, but damaging shocks occur occasionally outside these areas. Examples in the United States are New Madrid, Missouri, and Charleston, South Carolina. Many years, however, usually elapse between such destructive shocks.


this is a very brief ans and you can get all the points for your ans in it!!!

The most countries which are affected by volcanoes and earthquakes frequently are Eastern Caribbean Islands, USA (California), Japan & Chile because this countries are located near the boundaries of the plates so they affected this disastrous disaster.
