A 5.4-magnitude aftershock hit Searles Valley, California – the epicenter of Thursday’s powerful earthquake.
The tremble was reported on Friday at about 4.07am local time, according to the US Geological Survey (USGS).
The first earthquake, a magnitude-6.4, occurred on the morning of Independence Day and was felt from Las Vegas to San Diego, reported NBC Los Angeles.
Several aftershocks – as many as 220 – followed within five hours of the original quake, but this is the strongest one yet.
Experts had predicted Thursday that the massive earthquake could lead to another, more powerful quake in the next week.
The aftershocks that were recorded measured between 2.8 and 4.7, according to the Southern California Seismic Network and USGS.
‘For a 6.5 quake you’d expect a lot of aftershocks,’ USGS expert Susan Hough told SFGate.
‘With any earthquake, there is a five percent chance something even bigger will happen within the next three days. If it did, it would be in the same remote area.’
Thursday’s earthquake struck in the morning, cracking roads, causing fires and downing power lines, although no serious injuries reported were reported.
