Mysterious seismic waves shake the Earth and scientists don't know why

Seismolog Göran Ekström from Columbia University told National Geographic, "I don't think I've seen anything like this."

"data-reactid =" 24 "> The researchers believe it was related to before & # 39; Swarm & # 39; earthquake off the coast of the Mayotte archipelago in the Indian Ocean.

The researcher detected strange, long and flat vibrations from the area, described as "very low frequency signals that are abnormal".

The signal is repeated every 17 seconds, lasting for about 20 minutes.

Nicolas Taillefer, head of the Bureau of Recherches Géologiques (BRGM) unit of earthquake and volcanic risk, said, & # 39; There are many things we don't know. That is something new in the signal at our station. "

The researchers think it might be related to the movement of a very large magma below the Indian Ocean, and said that the Mayotte island had actually moved 2.4 inches.

BRGM says, Therefore, this observation supports the hypothesis of a combination of tectonic and volcanic effects that explain geological phenomena involving seismic sequences and volcanic phenomena.

"This hypothesis needs to be confirmed by scientific research in the future."
