Mysterious seismic waves rippling around the world and no one has felt it or understood why: report



Seismic waves that began off the coast of Africa raced around the world this month, and nobody seemed wiser.

The waves began on November 1

1, about miles off the coast of Mayotte, a French island that lies between Africa and the northern tip of Madagascar, according to National Geographic. As the waves moved across the continent, they crossed Chile, New Zealand, Canada and finally Hawaii.

"I do not think I saw anything like that," said Göran Ekström, a seismologist at Columbia University who studies unusual earthquakes.

Its features were unusual, from low-frequency ring to propagation.

While the event went unnoticed, a person saw curious zigzag effects in the US Geological Survey's real-time seismogram posted on Twitter. This has attracted the attention of researchers around the world who wondered the source of the waves.

Ekström suspects that the waves may have started with an unnoticed earthquake.

The data makes it difficult to say what caused the event, said Helen Robinson, Ph.D. Candidate for Applied Volcanology at the University of Glasgow.

"It's really very hard to tell what the cause is and if everyone's theories are correct – even though what I'm saying has relevance to the outcome of the incident. "
