Azores on the island of Pico, is the highest point in Portugal, at . If measured from their base at the bottom of the ocean to their peaks, which thrust high above the surface of the Atlantic, the Azores are actually some of the tallest mountains on the planet. The climate of the Azores is very mild for such a northerly location, being influenced by its distance from the continents and by the passing Gulf Stream. Due to the marine influence, temperatures remain mild year-round. Daytime temperatures normally fluctuate between and depending on season. Temperatures above or below are unknown in
Azores hotspot from Azores Plateau, which is an area of thickened oceanic crust and is thought to be formed from the Azores hotspot 20 Mya. This has been shown through mapping negative velocity S-wave anomalies beneath the Azores. This has shown that beneath the Azores Plateau there is a negative anomaly limited in the upper 250–300 km which is suggestive to be a signature to a present-day dying plume which would have created the Azores Plateau. The Mid Atlantic Ridge offers a different perspective and insight into hotspots. The ridge acts as a cross section through the mantle plume. Anomalies on the
