On the second day 8 distinct eruption columns were discernable.

Several factors control the height that an eruption column can reach.

The approximate maximum height of an eruption column is given by the equation.

A dramatic increase in activity produced a high eruption column from a second vent, and pumice was deposited over a wide area.

These involved juvenile material originating in the collapse of the eruption column.

These are typically produced by lava dome collapse or collapse of the eruption column.

Each explosion was accompanied by thunder and a black eruption column ascending to a height of 1300 meters.

It lasted about five minutes, and the eruption column once again reached 24 km.

By 11:00 on 14 November 1963, the eruption column had reached several kilometres in height.

However, the eruption column was likely higher than the estimated data indicates because it does not include the highest portions of the column.
