On November 11, mysterious seismic waves caused a rumble in the Indian Ocean that reverberated around the globe. Low-frequency waves shook the entire Earth for about 20 minutes that day, but scientists now believe they know what caused that strange phenomenon.
Researches have declared that they don’t think any large earthquake was responsible for the worldwide rumblings. Instead, they feel that an eruption of an underwater volcano was to blame. Well, according to scientists, it was “almost certainly” an underwater volcano, anyway…
The rumble, which was described as a monotone ring, was picked up by seismographs almost 11,000 miles (18,000 km) from Mayotte and were spotted by happenstance. A New Zealand based Earthquake enthusiast who goes by the handle @matarikipax noticed unusual seismology readings from the United States Geological Survey. The agency publishes all of its recordings for free online, allowing anyone across the globe to trawl through its data. “This is a most odd and unusual seismic signal. Recorded at Kilima Mbogo, Kenya,” @matarikipax wrote on Twitter on November 11. “The signal can be seen all around the world.”
