There is no tsunami threat Monday morning after six earthquakes struck off the coast of British Columbia overnight.
Instead, they occurred about 118 miles southwest of Port Hardy, a town at the northeast corner of Vancouver Island.
The third quake was measured at 6.5 magnitudes at 10 kilometres by the USGS at 11:22 p.m., while the latest was a 4.8 at 17.8 kilometres deep, around 11:36 p.m.
Vaughan said the quakes were lightly felt onshore and that no injuries had been reported so far. "We do know it's occurred about 20 times in the past 10,000 years", Dr. John Clague, an earth sciences professor at Simon Fraser University, said to GlobalNews. "This is standard for earthquakes to happen in groups of three like this", he said.
At 11:22 p.m. a magnitude 6.5 quake struck the same area at a depth of 6 miles (10 kilometers).
There are 452 volcanoes in the 25,000-mile area.
The strongest one was a 3.8 magnitude natural disaster which hit 157 miles (253 km) off Kodiak.
He said: "The Ring of Fire is a girdle of volcanoes and quake zones that circles the Pacific Ocean, and which marks the join between some of the planet's most active tectonic plates".
Earthquakes are common in Japan as the country is located in an area where several continental and oceanic plates meet.
More than 1000 earthquakes take place around the world every year - majority in area sitting on the Ring.
