An expert in earthquakes breaks down what San Andreas gets so wrong, and what they get right.

Dr. Lucy Jones is a Los Angeles-based seismologist who was invited to the premiere of San Andreas, another summer blockbuster featuring The Rock battling other, bigger rocks.

Dr. Jones has spent her professional career studying earthquakes. She also has an itchy Twitter finger. During the screening, Dr. Jones tweeted her thoughts and observations. It turns out that story writers and special effects technicians don't know shit about earthquakes, but they do get some things right.

I'll let the expert take it from here.
