Mere seconds apart within a period of one minute, a series of three minor tremblors struck the Haida Gwaii archipelago off the B.C. coastal this morning.

The first two quakes occurred with epicentres located on shore.

The first struck at 10:58 a.m. this morning (November 9) with an epicentre, at a depth of five kilometres (three miles) located 54 kilometres (34 miles) south of Queen Charlotte.

Earthquakes Canada measured it as a 4.6-magnitude quake.

The second followed only a few second later at 10:58 a.m.

The epicentre was slightly west of the first one, at a depth of 10 kilometres (six miles), and was located 54 kilometres (34 miles) south of Queen Charlotte, 217 (135 miles) southwest of Prince Rupert and 312 kilometres (194 miles) southwest of Terrace.

Earthquakes Canada measured it as a 4.5-magnitude seismic event.

The third struck, which Earthquakes Canada listed as a 4.7-magnitude quake, hit several seconds later offshore.

The epicentre, at a depth of 23 kilometres (14 miles) was 57 kilometres (35 miles) south of Queen Charlotte, 217 kilometres (135 miles) southwest of Prince Rupert, 311 kilometres (193 miles) southwest of Terrace, and 743 kilometres (462 miles) northwest of Vancouver.

The U.S. Geological Survey, according to preliminary data, measured this third quake as 4.2 magnitude.

There weren’t any immediate reports of damage or tsunami risk from any of the quakes.
