Seismic waves shook the island off of Africa and hit Canada. Their cause is a mystery



If the season waves appear near the African island and get to Canada, does anyone feel it?

Apparently no – judging by the phenomenon that occurred at the beginning of this month.

Earthquake coverage Globalnews.ca:


An unusual seismological phenomenon occurred on May 11, the island of Madagascar on Mayotte Island.

Earlier the Twitter user @matarikipax, who posted the US Geological Survey data, revealed that they were discovered at the 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 in Canada (NRCan), later joined the clamor saying that the waves were discovered directly in Canada, Victoria, Haida Gwai, Toronto, Ottawa and Halifax.

Clearly, the waves were observed throughout the planet.

But nobody seems to have felt it, even if it happened, and this has made them secret, Cassidy told Global News.

No one can accurately explain why they happened.

Generally, the tectonic earthquake produces primary waves (P-waves) and secondary waves (s-waves), but it does not.

Earth crawled up and down every 17 seconds when the waves flooded – "very slowly shaking," said Cassidy.

The earthquake may have occurred, but if that happened, the event was definitely not "typical," he added.

"Based on seismic events and GPS molding data, it's possible that the volcanic link is the movement of magnetism, etc.," said Cassidy.

Seismic waves occurred in the area where this earthquake occurred.

According to the French geological inspector BRGM Mayotte, formed after volcanic activity, he saw "several hundred seismic events" recorded in the area that begins in May.

The first took place on May 10th. Five days later, the neighboring islands in the Comoros experienced a magnitude 5.8 earthquake, the largest ever recorded.

On Monday, 29 May, the Great Comoros, the largest of the three Comoros, smoke rises from the spearmint lava at 7,746 meters (2361 meters) of the Karthala Creek. The last time Mount Karthala broke out in April 2005.

There have been other seismic events in this area, but since July they have fallen.

"It indicates that since the crisis, seismic energy released has been weakened, although some earthquakes are still perceptible to the population," said BRGM.

The cause of Rome is still being explored, but researchers believe that this could be a combination of tectonic and volcanic effects – although this has not yet been confirmed.

The 2007 B.C. Interior Region was an earthquake that has never been recorded by the earthquake in the past.

Bars were due to the fact that magma is injected in the lower area of ​​the crust below the Anahima volcanic belt, a phenomenon that results in "high frequency, volcanic-tributary earthquakes and stinging fractures."

If volcanic activity is confirmed near Mayotte, then it would be the first to go beyond that area for more than 4,000 years.

Cassidy noted that this is also important for Western Canada, and there are also several volcanoes that have been powerless for thousands of years, and they could re-engage in the future.

"Understanding these signals from Mayotte will help us better understand the volcanic threat here in Canada," he said.
