Question: What direction is the Pacific Plate moving at the blue X ?

More Than 50,000 Seamounts

How Does a Seamount Grow?

Hotspots Make Seamount Chains

How Many Active Hotspots? = Present-day location of some select active hotspots

Western Pacific Hotspot Trails Press *6 to respond

How Fast does the Pacific Plate Move? 1841 km 26.6 13.0 7.2 5.1 Age of seamount in million of years

Poll Question: How fast does the Pacific Plate move?

How Fast does the Pacific Plate Move? Distance from Active Hotspot = 1841 km Age of a Hawaiian Seamount = 26.6 m.y. Rate of Pacific Plate at Hawaii = 1841 km / 26.6 m.y. = 69 km/m.y. So, the rate of the Pacific Plate at Hawaii is 6.9 cm/yr
