| 7. | These ash flows began the second series of high magmatism formations.
|
| 8. | A few ash flow tuffs also constitute this phase of volcanism.
|
| 9. | Volcanic activity mostly consists of explosive eruptions and ash flows.
|
| 10. | An ash flow from this explosion was recognised 2, 500 km west of the volcano.
