A volcanic complex is a geological formation that consists of multiple volcanic structures, such as volcanoes, lava domes, and craters. These complexes can form over long periods through repeated volcanic activity, where eruptions build up layers of lava and ash. They often feature a variety of volcanic features, making them diverse in shape and size. Volcanic complexes can be found in various locations around the world, often associated with tectonic plate boundaries. They can produce different types of eruptions, ranging from explosive to effusive, depending on the composition of the magma. Understanding these complexes helps scientists study volcanic activity and assess potential hazards.
