      After a major offshore quake hit Alaska two weeks ago, some notable earthquakes rumbled in Alaska early this morning.

      The quake struck at 12:52 a.m. local time (1:52 a.m. Vancouver time) on August 4.

      It was a shallow quake, being only four kilometres (2.5 miles) deep.

      The epicentre was located 35 kilometres (22 miles) northeast of Lake Minchumina, Alaska; 210 kilometres (130 miles) southwest of College, Alaska; approximately 200 kilometres (125 miles) southwest of Fairbanks, Alaska; and 922 kilometres (573 miles) northwest of Whitehorse, Yukon.

      It was followed by 3.8-magnitude quake (originally assessed as a 4.1-magnitude quake) at 1:13 a.m. local time (2 a.m. Vancouver time).

      This one was also at a depth of four kilometres (2.5 miles), with an epicentre positioned 29 kilometres (18 miles) southeast of Chase, Alaksa; 97 kilometres (60 miles) north of Knik-Fairview, Alaska; 133 kilometres (83 miles) north of Anchorage, Alaska; and 785 kilometres (488 miles) west of Whitehorse, Yukon.

      Meanwhile, quakes continue to shake the Alaska Peninsula in the wake of a 7.8-magnitude offshore quake that took place on July 21.

      One of the largest offshore temblors in recent days occurred on at 4 a.m. local time (5 a.m. Vancouver time) on August 4.

      This one was deep set, at a depth of 44 kilometres (27 miles). The epicentre was located 78 kilometres (48 miles) southwest of Sand Point, Alaska; and 979 kilometres (607 miles) southwest of Anchorage, Alaska.
