On Hawaii ... decrease in historical seismicity from the southeast to the northwest across the island chain is a result of Hawaii's geologic history—a unique combination of plate tectonics and hotspot volcanic activity. Figure 1 ... WebThere are three settings where volcanoes typically form: constructive plate boundaries. destructive plate boundaries. hot spots. Volcanoes do not typically occur at transform boundaries. One of the reasons for this is that there is little or no magma available at the plate boundary.

The joint mantle plume/hotspot hypothesis envisages the feeder structures to be fixed relative to one another, with the continents and seafloor drifting overhead. The hypothesis thus predicts that time-progressive chains of volcanoes are developed on the surface. Examples are Yellowstone, which lies at the end of a chain of extinct calderas, which become progressively older to the west.
