Volcanic eruptions are partly driven by pressure from dissolved gas, much as escaping gases force the cork out of a bottle of champagne. Beneath a volcano, liquid magma containing dissolved gases rises through cracks in the Earth’s crust.Volcanic ash is a mixture of rock, mineral, and glass particles expelled from a volcano during a volcanic eruption. The particles are very small—less than 2 millimeters in diameter. They tend to be pitted and full of holes, which gives them a low density.Pyroclastic rocks can be classified by their mode of formation into three main groups: ash fall deposits, ash flow deposits and surge deposits. Ash fall deposits. These form when volcanic material is explosively ejected from the vent up into an eruption column. There are five main types based on degree of fragmentation (i.e. size of ash particles): Volcanic Ash "ash" < 2 mm (.079 inch) Volcanic Dust (Fine Volcanic Ash) "ash" < 0.063 mm (0.0025 inch) * "Tephra" and "pyroclastics" are generalized names used for particles of igneous rocks of various sizes that have been ejected from volcanoes. They are classified by size. The terms "ash" and "dust" communicate a specific size of tephra or ...That is what appears to have happened on April 10-11, 2023.
