What about volcanoes? ¿Habla español?

| Just
like there are different types of volcanoes, there are also different kinds
of eruptions! There
are eight different types. Can you name them all? FISSURE ERUPTIONS In Fissure-type eruptions, spurts of lava and molten flow out of the fissure located on the volcano's rift zone which then stream into the already flowing lava going down the slope HAWAIIAN ERUPTIONS These eruptions usually occur along the fractures or fissures that serve as linear vents, and sometimes they also transpire in the central vent. STROMBOLIAN ERUPTIONS These eruptions consist of huge clots of molten lava bursts that arise from the summit crater and then they form luminous arcs through the sky VULCANIAN ERUPTIONS When the crater explodes dense clouds of ash-laden gas detonate then ascend above the peak. The steaming ash then begins to form a whitish cloud toward the top level of the cone. PLINIAN ERUPTIONS Plinian eruptions are the most powerful eruption type. They involve the explosive discharge of fairly thick lava and fast-moving deadly pyroclastic flows ("nuées ardentes") HYDROVOLCANIC ERUPTIONS There are two types of hydrovolcanic eruptions: Surtseyan and phreatomagmatic. These develop when the water is less than 100m deep which makes it easy to create explosive expansion of the steam thus takes place near the surface in an open vent. The generated energy is isolated into the eruptions, and usually last until the magma no longer rises or until a mass of fragments stop the water from invading the channel of the volcano. In surtseyan eruptions, steam clouds and ash usually form thickly and can reach up to 5km in height. They are shaped in dark-pointed jets of fragments and are often followed by bombs that shot out of the vents CENTRAL VENT ERUPTIONS In central vent eruptions, a fountain of sweltering lava spurts to up to a couple hundred feet and more PHREATIC ERUPTIONS: These eruptions are also known as steam blast eruptions. They are driven by the explosive expanding steam that came from the surface water, or cold ground that came mixed with the magma, or hot rock |
