The Canary hotspot is a volcanichotspot located at the Canary Islands off the north-western coast of Africa. The Canary hotspot is believed to be underlain by a mantle plume that is relatively deep. It is believed to have first appeared about 60 million years ago.[1] Cleveland Volcano in the Aleutian Islands of Alaska photographed from the International Space Station For other uses, see Volcano (disambiguation). ...

The Canary Islands developed in a geodynamic setting characterized by Jurassic oceanic lithosphere formed during the first stage of opening of the Atlantic at 180-150 Ma and lying close to a passive continental margin on a very slow-moving tectonic plate – the African plate.
Objections to this include that the ocean lithosphere around the Canaries is Jurassic, dike swarms in the submarine stages of Fuerteventura, Gomera and La Palma have different strikes, the rift geometry in each island is different and the islands are separated by deep sea with a lack of Cenozoic lithosphere added to the Mesozoic lithosphere.
There are several genetic hypotheses for the Canary Islands, including a propagating fracture, a local extensional ridge, uplifted tectonic blocks and an unifying model but it is generally assumed that the archipelago originated from residual old plume material in the upper mantle.
Canary's hot spot finder is the best of the several stand-alone Wi-Fi detectors that I've tried -- three of which I've gone so far as to purchase.
The Canary uses AAA batteries, rather than the button cells that some detectors do (harder to replace in a pinch); consequently it's not quite as svelte as some, but the extra goodies are worth the chubbier, still-palmable housing.
Canary's unit scrolls across its 12-character LCD display the name, channel and signal strength (4 bars is the highest) of the networks it finds, which makes it truly useful for checking where your own access point's signal reaches.
