Final answer:
The most explosive volcanoes erupt along subduction zones, such as the Ring of Fire in the Pacific Ocean.
Step-by-step explanation:
The most explosive volcanoes typically erupt along subduction zones, where one tectonic plate is forced beneath another. These areas are marked by intense volcanic activity due to the melting of the descending plate and the release of gas-rich magma. One notable example is the Ring of Fire, a region in the Pacific Ocean where the majority of the world's explosive volcanoes are located, including Mount St. Helens in the United States, Mount Fuji in Japan, and Mount Pinatubo in the Philippines.
