Magma shakes up earthquake locations

Diana Roman, AGU

Numerical models were employed to examine the relationships between the orientation of volcanotectonic faults and magma movement. It was found that the direction of movement on strike-slip faults should be opposite to that predicted on the basis of regional stresses. The results do not explain the location of some volcanotectonic earthquakes and that the locations of preexisting faults may be more important in influencing the location of these earthquakes.
