At the latitude of this earthquake, the Cocos plate moves north-northeast with respect to the Caribbean plate at a velocity of approximately 77 mm/yr, and subducts
beneath Central America at the Middle America Trench," reported USGS.
As well as showing the path of the trench (dark blue), it also depicts several guyots (yellow), or fiat-topped seamounts, that are being carried into the trench as the Pacific tectonic plate subducts
beneath the Mariana plate.
Notably, the Pacific plate subducts
below (is pushed underneath) northern Honshu along the Japan trench at a rate of 93 mm/yr.
The Australia plate subducts
beneath the Eurasian plate along the Java trench.
There, the India plate subducts
, or dives under, the Burma plate, much like the two plates that make up Cascadia.
On the other hand, African plate moves in NE direction and collides with the Eurasian plate and subducts
along the Hellenic-Cyprus Arc, somewhat retarding the westward movement of the Anatolian block and initiating its tendency to rotate to the SW.
A planet quakes, slides, uplifts, subducts
according to its wont.
In this case, the Caribbean plate subducts
, or slides beneath, the North American plate.
