Água De Pau Massif
Água de Pau Massif is a stratovolcano, stratovolcanic complex, located in the central part of the island of São Miguel Island, São Miguel, in the Portugal, Portuguese archipelago of the Azores. More recognizable for the Lagoa do Fogo at its centre, the volcanic complex includes centuries of geomorphological structures that include lava domes, cones and encrusted lava flows that have marked its history from, the last, 45,000 years BC. History The outer caldera dates from between 30,000 and 45,000 years ago, and comprises an area wide and long outer caldera (corresponding to the Água de Pau Massif).Pedro Freire (2013), p.15 The inner caldera, which is wide and long was formed about 15,000 years ago. It is the younger inner caldera that is partially filled by the crater lake Lagoa do Fogo. Until about 5000 years ago, activity in the caldera created several lava domes on the northern and western flanks. Some of the cinder cones on these flanks are marked by r ...

Azores Plateau
The Azores Plateau or Azores Platform is an oceanic plateau encompassing the Azores archipelago and the Azores triple junction in the North Atlantic Ocean. It was formed by the Azores hotspot 20 million years ago and is still associated with active volcanism. The plateau consists of a roughly triangular-shaped large igneous province that lies less than below sea level Mean sea level (MSL, often shortened to sea level) is an mean, average surface level of one or more among Earth's coastal Body of water, bodies of water from which heights such as elevation may be measured. The global MSL is a type of vertical .... A lack of age progression amongst the younger submarine and subaerial volcanism combined with excess melting as evident from the shallow water depth and the presence of islands in the Azores suggest it may fit the waning mantle plume.
