Magnetic anomalies in Puget Sound

Caption

Aerially collected magnetic data (background colors) of western Washington reveal that faults (black lines) on either side of the modern Seattle fault are oriented in different directions, suggesting a significant disconnect between the north and south. A massive tear between subducting and obducting (sinking and accumulating) material could have formed from the strain, authors of a new Tectonics study posit.
