On Sunday November 11, around 9.30 am, a progression of abnormal seismic waves moved the world over. Peculiarly, no person felt or saw it. Be that as it may, machines did. Scientists distinguished an unusual, long and level vibration from the territory, depicted as an 'atypical low recurrence flag.'
Seismologist Göran Ekström from Columbia University disclosed to National Geographic 'I don't think I've seen anything like it.'
Analysts trust it's connected to a past 'swarm' of tremors off the shoreline of the archipelago of Mayotte in the Indian Ocean. Mayotte is situated among Madagascar and Africa. In the wake of starting in the island, the seismic ripples moved all over Africa, in Zambia, Kenya, and Ethiopia. The signals went on for 20 minutes.
The analysts figure it might be identified with a tremendous development of magma under the Indian Ocean, and say that the islands of Mayotte have really moved 2.4 inches. The seismic movement was very like those seen after huge tremors. In an ordinary quake, the quickest voyaging sign known as essential or P waves achieve seismographs first.
Analysts are presently anticipating it could be a flow of magma underneath the volcanic island moving seaward or submerged shake. Be that as it may, the jury is still out on what caused these tremors.
