Japan

In subduction, specifically ocean-continent subduction, two plates move toward each other. This is similar to collision, except the denser plate, the ocean  plate, is forced under the continent plate. They do not push against each other to form mountains. However, the ocean plate carries water with it below the continental crust. This melts the extremely hot but solid rock. This magma bores its way up through the lithosphere to create volcanoes. Subduction can also result in a deep-sea trench bordering the land, and earthquakes. 

I am visiting Japan, where four different plates meet. I will visit the area near the Japan Trench, where the Pacific Plate is subducting beneath the North American plate. Although Japan's volcanoes are less talked about than its earthquakes, Japan is part of the Pacific Ring of Fire. The Sakurajima volcano erupted last February. Most people have heard of Japan's numerous earthquakes. Because Japan is surrounded by sea, this can cause devastating tsunamis. 

I have visited Nagasaki and some of the surrounding areas. It's hot and muggy here in the summer, but beautiful.
