The intense heat can cause water to boil and flash into steam, which results in an explosion of water, steam, rock and ash. "The water, once heated, begins to boil or can even flash straight to steam, causing an explosion," USGS said. During phreatic eruptions, however, no new magma is produced, only fragments of preexisting solid rock from the volcano.
Phreatic eruptions can also often precede, accompany or follow a more traditional volcanic eruption. —KG, GMA Integrated News.
