of rock from the Red Hill volcanic field reveals that it was erupted in two pulses, from 7.9-5.2 million years ago ( Mya) and from 2.5 to 0.071 Mya. The older activity was along a narrow zone roughly aligned with the lineament, while later activity was across a broad north-south zone, with the focus of activity tending to move south to north. Future activity is most likely in the northern part of the field.
