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
