The powerful quakes were said to be between 6.5 and 6.8 magnitude.

Six minutes later, a third 6.5-magnitude tremor was registered 138 miles southwest of Port Hardy - before a weaker 4.9 quake was recorded in the same place 14 minutes after that. They say there are a few reports of light shaking but no damage or tsunami is expected.

At 11:16 p.m., a magnitude 6.8 quake struck the same area at a depth of 13 miles (21 kilometers).

A series of three aftershocks measured between magnitude-4.3 and magnitude-4.9 followed the initial three earthquakes as well.

CBC meteorologist and seismologist Johanna Wagstaffe said the earthquakes are a reminder that in a "complicated" tectonic setting.

The horseshoe-shaped Ring of Fire, which is 25,000 miles-long, is known for its chain of volcanoes.

Professor Bill McGuire, Emeritus Professor of Earth Sciences at University College London explained to why the Ring of Fire is so unsafe.

Is there a tsunami alert on Canada coast after three 6 magnitude tremors hit? The quake caused a tsunami that hit the east coast of Japan.

More than 1000 earthquakes take place around the world every year - a lot of them in area sitting on the Ring.

"Looks like we have an natural disaster triplet, folks!"

"So far we are at roughly 1100 for 2018".
