What similarities and differences exist between a caldera and a lava plateau?

Answer 1

Both a lava plateau and a caldera are features that result from major volcanic activity.

A lava plateau is a raised feature that forms when very large amounts of runny lava erupt in a non-explosive fasion due to the low gas content. The lava cools to form volcani rock, which accumulates in layers over long periods of time, eventually forming an elevated feaature called a plateau.

A caldera is a lowered feature that forms as a result of an extremely large explosive eruption produced by very thick, gas-rich magma. The caldera forms as the eruption drains massive volumes of magma from the magma chamber and volcano above collapses into the space left behind, leaving a crater-like feature.

Answer 2

Both calderas and lava plateaus are formed by volcanic activity, but they are different in terms of their geological features. A caldera is a large, bowl-shaped depression that forms when a volcano collapses into its emptied magma chamber, while a lava plateau is a large, flat surface created by the accumulation of multiple lava flows that spread over a wide area. Additionally, calderas are typically associated with explosive volcanism, while lava plateaus are formed by effusive eruptions with low-viscosity lava.
