A mag 6.1 Japan, is the 38th straight major quake to rock the Pacific Ring Of Fire with the sequence going way back to the beginning of May: Mag 4.9 hits SoCal
An earthquake of magnitude 6.1 struck north of Japan’s islands of Okinawa on Saturday, the United States Geological Survey said.
There were no immediate reports of damage or casualties from the quake, which hit at a depth of 257 km (160 miles), about 346 km (215 miles) north of Naha, the capital.
In the last 24 hours, around 1,600 quakes have rumbled in the Ridgecrest area of Southern California, which is consistent with the previous day, however, one of them was a magnitude 4.9, the strongest there for a few days.
According to the La Times, in the past 10 days, there have been 649 earthquakes of magnitude 3.0 or greater centred nearby.
The aftershock was powerful enough to cause strong shaking — or level 6 on the Modified Mercalli Intensity Scale — at the unpopulated epicentre.
Moderate shaking, or level 5, was felt in Ridgecrest.
The quake was strong enough to wake some people in downtown Los Angeles and was felt as far away as Bakersfield, Death Valley and Orange County.
In the last 7 days, 11,197 have been registered have been recorded in the volatile area.
Further up the Western Coast of the US, Washington State yesterday was rocked by a mag 4.6 SSW of Three Lakes, and a mag 3.5, W of Monroe.
