Yes, that is correct! Most of the world's volcanoes are located around the Pacific plate, which is sometimes referred to as the "Pacific Ring of Fire." This tectonic plate is one of the largest on Earth and is characterized by intense volcanic and seismic activity. It spans the coasts of several continents, forming a ring that encompasses the Pacific Ocean. The plate boundaries associated with the Pacific plate, such as the subduction zones, are particularly prone to volcanic eruptions. Therefore, many of the world's most active and well-known volcanoes, including Mount St. Helens, Mount Fuji, and Mount Vesuvius, are found around the Pacific plate.
