    1 of 2 2 of 2

      Three earthquakes occurred this morning south of the border, one in Washington state and two in California.

      The first was a shallow quake struck in the San Jose area of Northern California.

      It occurred at 6:58 a.m. today, and was reported as felt.

      Although it originally registered as a 4.0-magnitude quake based on preliminary measurements,  the U.S. Geological Survey reassessed it as a 3.7-magnitude seismic event.

      At a depth of five kilometres (three miles), the epicentre was positioned 10 kilometres (six miles) northeast of Morgan Hill, California; 18 kilometres (11 miles) north of Gilroy, California; and 157 kilometres (98 miles) south of Sacramento, California.

      It was followed one minute later by a 3.5-magnitude quake, at a depth of four kilometres (two miles).

      The epicentre for this one was in the same area—17 kilometres (11 miles) north of Gilroy and 37 kilometres (23 miles) southeast of San Jose.

      About an hour and a half later, an earthquake struck Kitsap County in the Bainbridge Island area of Washington state, across Puget Sound from Seattle, this morning at 8:27 a.m.

      The U.S. Geological Survey measured it as a 3.2-magnitude quake at a depth of 26 kilometres (16 miles).

      The epicentre was located one kilometre (half a mile) northeast of Enetai, Washington; four kilometres (three miles) northeast of Bremerton, Washington; seven kilometres (four miles) southwest of Bainbridge Island, Washington; and 66 kilometres (41 miles) northeast of Olympia, Washington.
