Does not sound all that shallow to me.
11.87 miles/ 19.1 KM
Absolutely 19 miles (or even 19 kilometers) is deep in the earth by any ordinary standard, but the earthquake guys have their own peculiar way of looking at it.
“Quakes can strike near the surface or deep within the Earth. Most quakes occur at shallow depths, according to the U.S. Geological Survey. Italy’s quake was very shallow, originating between 2 1/2 miles (4 kilometers) and 6 miles (10 kilometers) underground, according to Italy’s geological service and the USGS. The magnitude measurements also varied slightly — between magnitude 6 and 6.2. By contrast, the 6.8 quake in Myanmar was deeper — at 52 miles (84 kilometers), which is considered an intermediate depth.”
