Mysterious low-frequency seismic ripples that stretched throughout the world last year may have been caused by the birth of a submarine volcano, scientists claim.

In 2018, unexpected seismic activity was picked up by seismographs 10,000 miles away and tremors were felt on the French island of Mayotte in the Indian Ocean.

Researchers - France - National - Centre - Scientific

Researchers at France's National Centre for Scientific Research (CNRS), wanted to clarify the origin of the small quakes which shook the island, located between Africa and Madagascar.

According to the French Geological and Mining Research Bureau, the team discovered a new 'submarine volcano' situated 31 miles (50 km) away.

Bureau - Birth - Volcano - Metres - Miles

The bureau said that the birth of the volcano, located 3,500 metres (2.1 miles) underwater, has been observed for the first time.

Rising from the ocean floor, the peak is estimated to be 2,600 feet high (800 metres) and three or four miles wide.

Mile - Km - Plume - Fluids - Point

They also claim that it has a 1.2 mile (2 km) long plume of volcanic fluids emanating from its highest point, or crater.

In previous maps, there had been nothing. 'This thing was built from zero in 6 months!' said Marc Chaussidon, director of the Institute of Geophysics in Paris (IPGP).
