The quake was estimated to be about 900 meters deep – that is very shallow. But the depth was correct to about 10 miles.

Some context
According to the USGS, there are about 20 Magnitude 7 earthquakes each year.
And because the Magnitude scale is logarithmic, a M7.1 is more than 10-times stronger than the 6.4 from the other day.
For those curious, a M7.1 earthquake is 5x bigger than a M6.4, but is 11.2x stronger in terms of energy release. The Richter scale is logarithmic; meaning, a M7.1 would be 10x bigger than a M6.1 and 100x bigger than a M5.1 (for example). #EarthquakeLA pic.twitter.com/ZVVHzTEEuQ

An important note for those in California…
Like any quake, today's M7.1 has a 1 in 20 of being followed by something even bigger. Smaller quakes – M5s are likely and a M6 is quite possible.
