'''Danan''' (uncertain derivation) (1460 ft) was one of the three
volcanic cones (the others being
Perboewatan and
Rakata) on the island of
Krakatoa, in the
Sunda Strait, in
Indonesia. It lay in the center area of the island, and may have been a
twin volcano. Danan was virtually destroyed in the eruption of
1883, only a rocky islet named 'Bootsmansrots' remains of it.
Form
Not much can be found about Danan; reports and some sketches indicate that it may have been a twin volcano. In a
woodcut made from the photograph of Perboewatan eruptiing in May 1883, another cone can be seen in the background, partially obscured by the ash cloud arising from Perboewatan. If this is Danan, it does not appear to be twinned and has a rather normal form. However, it may actually be Rakata's cone. At any rate, the background cone does not seem to be visible on published versions of the photograph itself.
Eruptions
1680-81
Danan apparently joined Perboewatan in eruption sometime after May, 1680, when Perboewatan started erupting. A returning Dutch traveler saw both cones erupting in February, 1681.
The 1883 Catastrophe
Perboewatan started erupting in May, 1883. In June, a black cloud hung over the islands for five days, and when it lifted on
June 21, Danan was seen to be erupting and continued through the
cataclysm of August 26-27.
R. D. M. Verbeek's reconstruction of the eruption has Danan destroyed at about 10:52 am,
August 27 in the last of the great explosions.
Bootsmansrots
'Bootsmansrots' ('
Bosun's Rock' in Dutch) is a small platform of rock composed of
parallel slabs tilted at about a 45-degree angle to the sea surface. It probably was an
extrusion dike in the flank of Danan and was stable enough to keep Danan from being destroyed in the major explosion at 10:02 am which destroyed the area to the south and the northern half of Rakata.
