A huge 6.4-magnitude tremor has battered California this morning, with locals saying it's the 'most intense they have ever felt'.
The US Geological Survey confirmed the quake hit at a depth of 10 miles at 2.34am near Eureka, in California's Humboldt County.
The recorded depth indicates the tremors were from a shallow earthquake, which is felt more strongly because it was closer to the surface.
