      When a 4.4-magnitude quake struck off the southwestern coastline of Vancouver Island on January 24, it was felt on Vancouver Island and in Metro Vancouver.

      After that, minor seismic activity continued in the Lower Mainland and near Vancouver Island. Although they were minor temblors, the shallow depths and proximity of these quakes to B.C. communities resulted in them being felt by residents.

      A 1.6-magnitude quake occurred at 10:54 p.m. on January 23, with an epicentre 3.5 kilometres (two miles) northeast of Agassiz, 19 kilometres (12 miles) northeast of Chilliwack, and 44 kilometres (27 miles) northeast of Abbotsford, according to the U.S. Geological Survey. 

      Although minor, its epicentre was at a depth of four kilometres (two miles).

      Accordingly, it was reported to be felt in the Fraser Valley.

      That was followed by a second minor quake at 9:22 a.m. on January 25.

      Earthquakes Canada measured it as 1.9-magnitude but the U.S. Geological Survey reported it as 2.4-magnitude.

      According to Earthquakes Canada, this one was also shallow, at three kilometres (two miles).

      The epicentre was located five kilometres (three miles) northeast of Agassiz, 15 kilometres (nine miles) northeast of Chilliwack, 40 kilometres (25 miles) northeast of Abbotsford, and 97 kilometres (60 miles) east of Vancouver.

      This one was also reported as lightly felt in Chilliwack and Abbotsford, although there were no reports of damage and none were expected.

      Meanwhile, other minor seismic activity continued near Vancouver Island. 

      The U.S. Geological Survey recorded a 1.6-magnitude quake at 2 p.m. on January 25 on Vancouver Island.

      The epicentre offshore from Oak Bay, at a depth of 16 kilometres (10 miles), was four kilometres (two miles) east of Victoria and 15 kilometres (nine miles) east of Langford.

      That was followed by a shallow 1.8-magnitude quake at 12:16 p.m. on January 26 on the Washington state side of the Strait of Juan de Fuca.

      The epicentre, at a depth of three kilometres (two miles) was 13 kilometres (eight miles) southwest of Anacortes, Washington, and 43 kilometres (27 miles) east of Victoria at a depth of three kilometres (two miles).
