A recent study provides new insights into the behavior of earthquakes based on a decade-long examination of precariously balanced rock formations that have remained upright despite being near fault lines.

Most rock formations are interesting to see while driving by, but one type in particular has had scientists intrigued for years. 
“Precariously balanced rocks” is what the research team calls these boulder stacks, which have somehow remained upright despite being in active earthquake areas in Southern California.
In fact, many have been dated to be
