Some geologic faults that appear strong and stable, slip and slide like weak faults. Now an international team of researchers has laboratory evidence showing why some faults that "should not" slip are weaker than previously thought. "Low-angle normal faults -- faults that dip less than 45 degrees -- are a problem," said Chris Marone, professor of geosciences, Penn State. ...
