The seismic signal that initially puzzled scientists was apparently a product of volcanic underwater activity, such as the inflating or deflating of calderas, or simply motion from a magma under the seabed.

A dedicated seismologist has apparently discovered the nature of a strange seismic event that has recently occurred near Mayotte, a French island between the African mainland and Madagascar in the Mozambique Channel

. In November, the scientists were of discovery a low-frequency tremor that triggered "seismic rumbling on a large part of the planet".

And now an independent seismology consultant named Anthony Lomax told The Daily Mail that the rumble was "almost certainly" caused by an "underwater volcanic eruption" the northeast of Mayotte. "

" Volcano caldera's inflation / deflation and collapse and the movement of magma under a volcano can produce a variety of seismic signals, including long periods and repetitive waves like the one observed on November 11, "Lomax explains.

The enigmatic rumble was first discovered on November 11, with low-frequency waves triggering sensors far from their original location, yet apparently unrecognized by the locals.

Between May and November of this year, the island of Mayotte was shaken by a series of weak earthquakes, with the strongest peaking at 5.8 on 15 May.
