      A sizeable offshore earthquake struck close to the Northern California coastline, while a strong undersea quake also rumbled off the Panama shore earlier today.

      The California coast temblor hit at 11:46 p.m. on July 17, and the U.S. Geological Survey measured it as a 5.1-magnitude quake.  

      At a depth of 26 kilometres (16 miles), the epicentre was located 36 kilometres (22 miles) southwest of Ferndale, California; 62 kilometres (38 miles) southwest of Eureka, California; and 323 kilometres (201 miles) northwest of Sacramento, California.

      The U.S. Tsunami Warning Centre stated that there is no tsunami danger from this earthquake for the U.S. West Coast, British Columbia, or Alaska.

      Meanwhile, a 6.1-magnitude quake struck south of the Panama coastline at 4:56 p.m. Panama City time (1:56 p.m. Vancouver time), according to the U.S. Geological Survey. 

      It occurred at a depth of nine kilometres (six miles).

      The epicentre was located 130 kilometres (81 miles) south of Punta de Burica, Panama; 157 kilometres (97 miles) south of Puerto Armuelles, Panama; and 166 kilometres (103 miles) south of Pedregal, Panama.

      It was followed by a 4.2-magnitude quake at a depth of 10 kilometres (six miles) at 9:56 p.m. in the same area. 

      A tsunami warning wasn’t issued for these quakes either.
