Description :
This paper describes the post-1883 history of volcanic disturbance to the islands Panjang and Sertung, within the Krakatau group, Indonesia. The results of analyses of chemical, physical and particularly of mineral magnetic properties are presented, with the aim of assessing spatial variation in ash fall history across Panjang and Sertung. Most sites on both islands showed evidence of a number of distinct ash-falls in both the early 1930s and 1952/53 periods, of a highly disruptive nature. Sites nearest the Anak Krakatau typically contained evidence of the largest number of different ashes. The implications of these data for the biogeography of the group are briefly discussed.
