context_page_description: Phreatomagmatic eruptions are volcanic eruptions resulting from interaction between magma and water. They differ from exclusively magmatic eruptions and phreatic eruptions. Unlike phreatic eruptions, the products of phreatomagmatic eruptions contain juvenile clasts. It is common for a large explosive eruption to have magmatic and phreatomagmatic components.
