Three strong earthquakes struck early Saturday off the B.C. coast, about 230 kilometres north-northwest of Port Hardy, the U.S. Geological Survey said.

The first occurred at 2:39 a.m. PT and had a magnitude of 5.6. That was followed by a pair of quakes, one recorded at 3:01 a.m. and another at 3:44 a.m. Both had a magnitude of 6.5.

All three were recorded in the same area, at a depth of about 10 kilometres.

The quakes were felt by some residents of Bella Bella and residents of northern Vancouver Island and the southern regions of the Queen Charlotte Islands. There were no reports of damage.

The Alaska and West Coast Tsunami Warning Center said a tsunami was not expected for coastal regions.

VANCOUVER (News 1130) - People living in the Bella Bella region got a rather rude awakening this morning. Four significant earthquakes struck off the BC coast before the break of dawn.

Stephane Mazzotti, a seismologist with Natural Resources Canada, says, "We had two big earthquakes, magnitude about 6.5 each, pretty much in the same location about 200km west of Bella-Bella about halfway between the southern tip of the Queen Charlotte Islands and the Northern tip of Vancouver island." He added, "They were about 45 minutes apart. One at 3:00 and one at quarter to 4:00."

There was also two earthquakes with magnitudes around 5.3 which preceeded and followed the two big ones. In total, there were nearly 20 earthquakes in the region overnight but most of them were not significant.

No major damage has been reported and a tsunami warning has not been issued.

These are the first earthquakes over a magnitude of 6 since 2004, when a 6.6 quake hit off the BC Coast near Port Alice.

6級地震再襲卑詩外海 2008年1月10日
(維多利亞九日加新社電)卑詩中部對開海域在早上6時40分發生6.2級地震。

加拿大地質學調查局的地震學家馬索蒂(Stephane Mazzotti)表示，工作人員仍然在尋找發生地震的精確位置和深度，不過已知地震大概發生在沙洛皇后島南端的外海。

他表示，這次地震令人關注，因為上周六在區內亦發生了兩次6.5級的地震。

他再指出，今天的地震並不是上一次的餘震，因為地震強度相若，不過他指出，這次地震可能是被上一次地震所引起。

他估計，遠在275公里外的溫哥華島北部的居民亦可感受到這次地震，不過這次地震威力未達到破壞強度，也毋須發出海嘯警告。

馬索蒂表示，這次地震發生在活躍的地震帶，雖然自上周六已發生三次地震，並不代表預測已久的大地震將襲擊卑詩南部海岸。
