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.
