Vulcanian Eruptions Description, Examples and Diagram
Vulcanian eruptions are moderately explosive eruptions characterized by intermittent, short-lived explosions of ash-laden, convoluting dense clouds rising high above vents
Vulcanian eruptions are moderately explosive eruptions characterized by intermittent, short-lived explosions of ash-laden, convoluting dense clouds rising high above vents
Strombolian eruptions are mildly to moderately explosive eruptions characterized by pulsating or intermitted short-lived, discrete explosions that can go on
Plinian eruptions, also known as Vesuvian eruptions, are the largest, most explosive, powerful, and catastrophic of all volcanic eruptions. They
Pyroclastic flows, pyroclastic density currents (PDCs), or pyroclastic clouds are dense, ground-hugging, hot gases laden with volcanic debris racing down
Andesitic magma or lava has an intermediate composition with moderate silica content between 57 and 63 wt. %. Its composition
Magma refers to hot, molten, or semi-molten rocks under the Earth’s surface, while lava refers to magma that makes it
To understand intermediate magmas and lavas well and their characteristics, you need to know their composition lies between mafic and
Felsic magmas and lavas are proportionately higher in lighter elements like oxygen, silicon, aluminum, sodium, or potassium and lower in
Mafic magmas and lavas are the most common on Earth. The other relatively common ones are intermediate and felsic. Lesser
