A swarm of small earthquakes is currently striking in between Tenerife and Gran Canaria. Although it seems to slow down, more than 270 earthquakes hit the area since April 29, 2018. And it doesn’t seem we are nearing a stop. That’s pretty scary knowing Teide volcano – Earth’s third-tallest volcanic structure – is nearby.
Today only three low magnitude earthquakes have been detected between the islands of Tenerife and Gran Canaria. But already 270 earthquakes have been detected in the area since Sunday, April 29, 2018.
This video shows the evolution of the earthquake swarm between Tenerife and Gran Canaria since April 29, 2018:
According to a recent research there is a huge submarine fault between Gran Canaria and Tenerife exactly where the current quake series evolves. This huge trench extends from East-Northeast to West-Southwest, reaches depths between 6,000 and 13,000 below the seabed and has a volume of 2,100 to 10,000 cubic kilometers.
According to their conclusions, this fault between Tenerife and Gran Canaria has not been active in recent times, but has probably conditioned the rise of magma in the central part of the archipelago during the first growth stages.
And what if it started spewing magma again? And what if it was reactivating the Teide volcano? That would be cataclysmic.
