Several earthquakes recorded around Haida Gwaii in early August

Several earthquakes were recorded around Haida Gwaii during the first week of August, including two moderate earthquakes measuring above magnitude 4.

The largest occurred early on Aug. 3.

The U.S. Geological Survey recorded the magnitude 4.8 earthquake at 2:17 a.m. PDT at a depth of 15 kilometres. The epicentre was offshore near northern Haida Gwaii.

The U.S. Geological Survey described the location as 152 kilometres south of Hydaburg, Alaska, while EmergencyInfoBC described the same earthquake as approximately 185 kilometres southwest of Prince Rupert.

EmergencyInfoBC reported there was no tsunami threat to B.C. following the earthquake. The U.S. National Tsunami Warning Center also issued an information statement saying there was no tsunami danger from the event.

Later that day, Earthquakes Canada recorded a smaller magnitude 2.1 earthquake approximately 46 kilometres northwest of Masset. The earthquake, recorded at 11 a.m. PDT on Aug. 3, had a depth of about 3.4 kilometres.

Another small earthquake was recorded on Aug. 5. Earthquakes Canada measured that event at magnitude 2.4, approximately 47 kilometres southwest of Daajing Giids, at a depth of about 20 kilometres.

The strongest locally reported shaking of the week came early Aug. 7, when a magnitude 4.3 earthquake occurred approximately 79 kilometres west-northwest of Daajing Giids.

Earthquakes Canada recorded the earthquake at 4:48 a.m. PDT at a depth of 17.6 kilometres and listed the event as felt.

The four earthquakes were recorded within a five-day period, although there is no indication from earthquake authorities that the events represent an unusual sequence or are necessarily related.
