      Original article (January 22):

      A number of earthquakes have been taking place in Alaska and northern British Columbia over the past few days.

      An inland earthquake struck southern Alaska near the Yukon border at 10:10 a.m. today (January 22).

      The U.S. Geological Survey measured it as a 4.0-magnitude temblor before reassessing it as a 3.9-magnitude seismic event, which matched the Alaska Earthquake Centre’s measurement.

      Close to the surface at a depth of four kilometres (two miles), the epicenter was located 118 kilometres (73 miles) northwest of Yakutat, Alaska, and 352 kilometres (218 miles) southwest of Whitehorse, Yukon.

      This quake follows one in northern B.C. that hit near the Alaska Panhandle and the Yukon border at 8:11 a.m. on January 20.

      Earthquakes Canada reported it as a 4.0-magnitude quake that was lightly felt in Whitehorse and Haines Junction, Yukon. There weren’t any reports of damage.

      It was a surface-level quake, at a depth of one kilometre (or half a mile).

      The epicenter was located 72 kilometres (45 miles) west of Skagway, Alaska, and 135 kilometres (84 miles) southwest of Whitehorse.
