VANCOUVER - A third minor earthquake has struck off the north B.C. coast, the latest in a series that has rattled the area since last fall.

The West Coast-Alaska Tsunami Warning Centre in Palmer, Alaska, says the third quake hit at 7:28 p.m. Thursday, 72 kilometres south of Sandspit on the Haida Gwaii islands.

The centre says quakes with magnitudes of 4.6 and 4.3 struck about 75 kilometres south and 97 kilometres southwest of Sandspit just hours earlier.

The centre says there was no tsunami danger from any of the quakes.

Two other quakes of similar magnitudes occurred in February in the same region.

A 7.7 earthquake rocked Haida Gwaii in October, the strongest recorded in Canada since an 8.1 shaker hit the same area in 1949, but no damage was reported.
