This is the relevant bit... > The Blanco Fault Zone is a transform, or strike-slip, boundary; that means it's where tectonic plates slide along one another. The most dangerous and powerful faults are usually seen in subduction zones, where one plate dives beneath another. I was initially concerned about tsunamis - but this implies they don't occur on these types of fault lines. ...still... it's a good excuse to take a moment to think about preparedness. If you live on the coast - consider the most efficient inbound evacuation routes.
