Mamoudzou by plane, Mayotte island
ON November 11, seismic stations across the planet recorded a mysterious seismic reading, with characteristics that “had never been observed before,” according to the American seismologist Göran Ekström.
The Volcanological Institute of the Canary Islands (Involcan) echoed this view yesterday, reporting through their social networks that “this signal is very different from the seismograms normally associated with earthquakes, having an oscillatory character that can be explained only by invoking a phenomenon of volcanic type “.
The epicentre of this unusual earthquake was located about 24 kilometers east of the volcanic island of Mayotte, in the Indian Ocean.
In this same area, since last May, a series of earthquakes with a magnitude of up to 5.8 have been recorded.
At the same time, the GPS stations deployed on the island of Mayotte recorded a deformation of the terrain, which seems to indicate the emptying of a giant magmatic chamber, located in the same area as the earthquakes, explains Involcan.
The waves vibrated through Africa. They crossed oceans, leaving signals throughout Chile, New Zealand, Canada and even Hawaii, located almost 18,000 kilometers away from Mayotte, explains National Geographic.
For the moment, scientists have not been able to decipher what caused the tremor.
