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.
