Hot Spots. A major hot spot in the Pacific ocean created the Hawaiian Island and Emperor Seamount island chains.

More than a trip south.   Most of the world’s volcanism is associated with divergent and convergent plate boundaries.  However there are sites of volcanism.

Determine Pacific Plate Velocity YOUR ASSIGNMENT Determine Pacific Plate Velocity Distance is measured from where we think the hotspot (most active volcano) is right now. Age is how old the island is in millions of years (Ma). Use a data set of ages and distances from the active hotspot from the Hawaii-Emperor seamount chain. Determine the velocity of the Pacific Plate.

AVAILABLE DATA Note that the green and blue columns contain the data you will be plotting. Start plotting from Volcano #91.
