The 7.1 magnitude earthquake that rocked California Friday didn’t result in any casualties but it’s nothing to shrug off either.
Satellite imagery captured by Planet Labs shows the earthquake created a new fissure in the Earth’s surface that’s so big it can easily be seen from space.

Before and after photos captured by Planet Labs on 4 July and 6 July shows a big crack in the surface of the earth close to the epicenter of the quake, which hit 11 miles north-northeast of Ridgecrest, California. Planet Labs Chief Executive Will Marshal showed off the before and after satellite imagery on Twitter.
According to reports, the crack goes through the Mojave Desert and across a highway. The fissure measured in at around two inches wide but gets deeper as it stretches out. The crack has become a tourist spot of sorts for some Californians. Residents of Ridgecrest and those from other parts of the state visited the fissure to see for themselves. Some used the opportunity to snap selfies with the earthquake caused crack.
Chance of Similar Size Quake Low
The United States Geological Survey (USGS) said the earthquake was the result of shallow strike-slip faulting in the crust of the North America plate. It occurred about 34 hours after a 6.4 magnitude quake in the same region on 4 July.
“This region of eastern California has hosted numerous moderate sized earthquakes,” the United States Geological Survey said on its website. “Over the past 40 years, prior to the July 4th event, 8 other M5+ earthquakes have occurred within 50 km of the July 6th, 2019 earthquake. The largest of these was a M 5.8 event on September 20, 1995, just 3 km to the west of today’s event, which was felt strongly in the China Lake-Ridgecrest area, and more broadly from Los Angeles to Las Vegas.”
The USGS predicted that over the next week there is a less than 1% chance of one or more aftershocks that are bigger than the magnitude 7.1. It is likely there will be smaller earthquakes during the week, with the number of aftershocks declining over time. The USGS did warn that a large aftershock can temporarily increase the number once again.
Californians on Edge
Despite the likelihood of a 7.1 magnitude aftershock in California that hasn’t stopped rattled residents from sleeping outdoors and prompting California Governor Gavin Newsom to call for a strengthening of the alert systems and building codes in the state. “It is a wake-up call for the rest of the state and other parts of the nation, frankly,” Newsom said at a news conference after the earthquakes.
