Krakatau
In January of 1960 a group of scientist visited Anak Krakatau to record
its renewed activity and to measure changes in the size and shape of
the island. They observed explosive eruptions of pyroclasts from ash
to boulders in size. This photograph shows a column of ash rising
above the island. Rakata, a remnant of the volcano prior to the 1883
eruption, is in the background.
