If seismic waves appear on an island outside of Africa and hit Canada, does anyone feel it?
Obviously not – Judging by the phenomenon that manifested itself earlier this month.
Earthquake Coverage at Globalnews.ca:
An unusual seismological phenomenon originated near the island of Mayotte, on the coast of Madagascar on November 11.
They were unveiled at an early stage by Twitter @matarikipax, who published data from a geological survey of the US showing that they were detected at a Kilima Mbogo monitoring station in Kenya.
The same user tweeted that waves were also found in Zambia, Ethiopia, Spain and New Zealand.
John Cassidy, an earthquake seismologist with natural resources Canada (NRCan), later joined the burst, saying that waves were detected across Canada, Victoria, Haida Gwaii, Toronto, Ottawa and Halifax.
Obviously, waves have been seen all over the planet.
But it seems that nobody felt them, not even where they came from, and that gave them the secrets of secret auras, Cassidy told the Global Rapporteur.
No one can explain exactly why it happened.

Usually the tectonic earthquake generates primary waves (P-waves) and secondary waves (s-waves), but this also did not produce.
The earth moved up and down every 17 seconds when the waves flowed – "Creeping very slowly," Cassidy said.
It is possible that the earthquake occurred, but if so, the event was definitely not "typical," he added.
"Based on data on seismic events and GPS formations, there is probably a volcanic connection – the movement of magical chambers, etc." Cassidy said.
Seismic waves originate from an area where an "earthquake" occurred earlier this year.
Mayotte, which was a volcanic activity, recorded "several hundred seismic events" in May, as the French geological inspector BRGM said.
The first one happened on May 10th. Then, five days later, the neighboring island of Comoros saw the magnitude-5.8 earthquake, which was the largest one ever recorded.
There have been other seismic events in the area but have diverged since July.
"This suggests that the relaxed seismic energy has weakened since the beginning of the crisis, although some earthquakes are still felt by the population," BRGM said.
The cause of the swarm is still being investigated, but scientists believe it may be a combination of tectonic and volcanic effects – although it has not yet been confirmed.
The interior of the B.C. recorded a quake swarm in 2007, after never having seen an earthquake in the past.
The rod was attributed to the magma injected into the lower bark beneath the Anahim volcanic belt, a phenomenon that produces "high frequency, volcanic-tectonic earthquakes and spasmodic explosions."

If volcanic activity was confirmed near Mayotte, then it would be the first to be in the area for more than 4000 years.
And it depends on Western Canada, Cassidy remarked – and there are a number of volcanoes that are dormant for thousands of years and could be activated again in the future.
"Understanding these signals from Mayotte will help us better understand the volcanic danger in Canada," he said.
