Seismic sensors are first and foremost between Madigascar and Africa. Then, chile, New Zealand and Canada.
Hawaii, it was also picked up the ‘event’.
Nobody knows what it was.
Meteorite? Submarine volcano? Nuclear test?
“I don’t think I’ve seen anything like it,”National geographic reports Colombia University seismologist Göran Ekström as saying. “It doesn’t mean that it’s exotic.”
Mayotte, United Kingdom. It’s been subject to a swarm of earthquakes since May. It was a minority of 5.8.
But, the earthquake swarm had been down before the mysterious ringing was detected earlier this month.
Event was weird. This is how much it has been sustained.
Earthquakes, by their very nature, usually register as short-sharp cracks ’. Hey, it’s not a bad thing.
The first signal is a wavelet of high-frequency compression waves.
Then comes a Secondary wave: these high-frequency wiggle’s somewhat more.
Only then comes the surface of the waves: these are slow, deep rumbles and several times.
The November 11 event is notable.
Registered wave, resonate the surface. And it didn’t ‘rumble’ as an earthquake’s surface wave tends to. Instead, it is maintained a much cleaner – almost musical – frequency.
National Geographic reports the French Geological Survey report on the coast of Mayotte. While the island was created by volcanic activity, it’s been a dormant for more than 4000 years.
If you’re liking it, you can’t get it. 50km off the coast and under water. This sensor is supported by GPS sensors. It could be less than five months.
But it’s a poorly mapped region. Can not be guessed at.
It couldn’t have been caused by a magma.
But he’s not certain.
