Hello everyone - I have a dumb question- how do the geologists know if this location has a fault or not?
US Geological Svc has great tools and info for all levels.
Here's the beginners section

Here's the Advanced Faulting section.

@Bliss My problem is - HOW did they know that stuff?
@Bliss My argument is: How did the geologists know there are faults in New Madrid, Charleston and Central Virginia?
@Bliss Please do share the links and answers! I'd like to know as well. I'm currently in a zoom with friends - we had been talking about how we detect the "aquifers" and fault lines. We are curious and we would like to know how.
