Phreatomagmatic eruption - Wikipedia
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 (magmatic) clasts. [1]
Phreatomagmatic (Hydrovolcanic) Eruptions - U.S. National ...
2023年4月14日 · Violently-explosive eruptions driven by steam explosions produced by the interaction of hot magma with surface water or shallow groundwater. Hydrovolcanic eruptions include tephra derived from juvenile magma.
What Are Phreatomagmatic Eruptions and How They Form?
2024年1月10日 · Phreatomagmatic eruptions happen when hot, rising magma directly interacts with underground or shallow surface water. Water will flash into steam, expand, and cause an explosion. This explosion will eject water droplets, steam, ash, lapilli, blocks, or bombs into the air.

Phreatomagmatic eruption column rising from the east Ukinrek Maar crater, Alaska. Photo taken about 5:00 PM, view is to the southeast. An eruption that involves both magma and water, which typically interact explosively, leading to concurrent ejection of steam and pyroclastic fragments.
What is a Phreatomagmatic Eruption? | Volcano Glossary - Perlan
A phreatomagmatic eruption is a type of volcanic eruption that results from the explosive interaction between magma and water. When magma touches groundwater, surface water, or water-rich rocks, it rapidly converts water into steam.

Magmatic eruptions range from quiet effusions of lava to extremely explosive eruptions that can blow apart mountains and send ash clouds around the globe. Read more. Phreatomagmatic eruptions include fresh lava or tephra, but also include violent steam explosions caused by the interaction of hot magma or lava with water. Read more.
