VA Fault Lines (Magnetic Data)

Map showing magnetic data along the VA crossroad fault lines

Detailed Description

 In map view, magnetic data were filtered (colors) to highlight geologic features near the earthquake depth. One contrast (blue dotted line) is aligned with aftershocks (black dots). The other crosses at an angle. They suggest that the earthquake (yellow star) occurred near a “crossroads,” or a complex intersection of different types of rock.
