Answer:
Subduction zones are often located in good places for seaports.
Explanation:
The Ring of Fire is located on the edges of the Pacific Ocean. It lies near subduction zones, thus near convergent plate boundaries where plates go below other plates, triggering the formation of volcanic island arcs. This is also tectonically the most active area in the world, with volcanic eruptions and earthquakes being regular occurrences, and every now and then there are devastating tsunamis as well.
Despite these circumstances, there a lot of people living on the Ring of Fire. In fact, there is a high density of populations living in it, with Japan, Indonesia, the Philippines, all being good examples for it. The reasons why people live there though are because the subduction zones, almost always, tend to create places that are excellent for seaports, thus trade. Also, the soil tends to be of very high quality because of the volcanic ash, so people are able to produce goods on a large-scale without any expenses for fertilizers, and in many cases chemicals as well.
