A lava plateau is a flat, wide surface (plateau) that is formed when lava comes out of the ground and spreads out very quickly. The lava layers form a lava plateau. With each eruption and flow of lava, the plateau grows in size.
The differences are that Pahoehoe produces fast moving lava; Aa produces slower moving lava. The kind of eruption that produces these types of lava is a quiet eruption.
Lava fountains can be associated with Strombolian and occasionally Hawaiian eruptions.
Quiet eruptions
Pahoehoe and AA lava are produced by quiet eruptions. This means that instead of a blast or explosion, the lava just flows out of the volcano. Pahoehoe lava is hot and flows quickly. AA lava is cooler in temperature and doesn't flow as quickly.
Hot lava comes from effusive eruptions, where magma is relatively low in silica and flows easily out of the volcano. This type of eruption typically results in slow-moving lava flows that can cover large areas.
Scientists can determine the type of eruption by studying features such as the size and shape of the lava flows, the presence of gas bubbles or vesicles, and the composition of the minerals within the cooled lava. Different types of eruptions result in different lava compositions and textures, providing clues to the eruption style and intensity. By analyzing these features, scientists can infer whether the eruption was effusive (gentle, with slow lava flows) or explosive (violent, with ash and pyroclastic flows).
Mount Shasta primarily produces andesitic lava, which is a type of intermediate lava characterized by a medium viscosity and silica content. This type of lava typically results in eruptions that produce a combination of lava flows and explosive eruptions.
Malwa Plateau
The eruption of the boiling hot lava sent the small town into panic.
A quiet, non explosive eruption. Silica-high lava produces explosive eruptions.
first lava flows out of several long cracks in an area. the thin runny lava travels far before cooling and solidifying. again and again floods of lava flow on top of earlier floods. After millions of years these layers of lava can form high plateaus!
