Krakatau, a small island group in the Sunda Strait between the islands of Sumatra and Java is one of the world's most famous volcanoes. It is a mostly submerged caldera with 3 outer islands belonging to the rim and a new cone, Anak Krakatau, that has been forming a new island since 1927 and remains highly active.
Krakatau exploded spectacularly in a devastating Plinian eruption 1883 that killed more than 30,000 people (mostly by the huge tsunamis triggered by the eruption). The eruption was one of the first global news events after telegraph lines had connected the different continents.

Sfondo

The renowned volcano Krakatau (or Krakatoa) lies in the Sunda Strait between Java and Sumatra. Collapse of the ancestral Krakatau edifice, perhaps in 416 AD, formed a 7-km-wide caldera. Remnants of this ancestral volcano are preserved in Verlaten and Lang Islands; subsequently Rakata, Danan and Perbuwatan volcanoes were formed, coalescing to create the pre-1883 Krakatau Island. Caldera collapse during the catastrophic 1883 eruption destroyed Danan and Perbuwatan volcanoes, and left only a remnant of Rakata volcano. This eruption, the 2nd largest in Indonesia during historical time, caused more than 36,000 fatalities, most as a result of devastating tsunamis that swept the adjacent coastlines of Sumatra and Java. Pyroclastic surges traveled 40 km across the Sunda Strait and reached the Sumatra coast. After a quiescence of less than a half century, the post-collapse cone of Anak Krakatau (Child of Krakatau) was constructed within the 1883 caldera at a point between the former cones of Danan and Perbuwatan. Anak Krakatau has been the site of frequent eruptions since 1927.

Krakatoa - the world's most infamous volcano

The island group of Krakatoa (or Krakatau) lies in the Sunda Strait between Java and Sumatra.  Krakatoa is infamous for its violent Plinian eruption in 1883, that destroyed the previous volcanic edifice and enlarged its caldera.
Collapse of the former volcanic edifice, perhaps in 416 AD, had formed a 7-km-wide caldera.  Remnants of this ancestral volcano are preserved in Verlaten and Lang Islands; subsequently Rakata, Danan and Perbuwatan volcanoes were formed, coalescing to create the pre-1883 Krakatoa island.  Caldera collapse during the catastrophic 1883 eruption destroyed Danan and Perbuwatan volcanoes, and left only a remnant of Rakata volcano. 
This eruption, the 2nd largest in Indonesia during historical time (the most violent being the eruption of Tambora in 1815), caused more than 36,000 fatalities, most as a result of devastating tsunamis that swept the adjacent coastlines of Sumatra and Java.  Pyroclastic surges traveled 40 km across the Sunda Strait and reached the Sumatra coast.  After a quiescence of less than a half century, the post-collapse cone of Anak Krakatoa ("Child of Krakatoa") was constructed within the 1883 caldera at a point between the former cones of Danan and Perbuwatan.  Anak Krakatau has been the site of frequent eruptions since 1927.

Durante questa spedizione fisicamente facile, hai un'occasione unica per sperimentare uno dei vulcani più belli e potenti del mondo. A seconda di quale data, abbiamo trascorrere 2-4 giorni e notti su e intorno a vulcano Krakatau e soggiornare un campo bellissimo su una delle isole.
Guardare i fuochi d'artificio di Krakatau quando è attivo è davvero spettacolare e possiamo andare a vari punti di vista sulle isole vicine e Anak Krakatau pure da una barca noleggiata a nostra disposizione.
Anche quando non c'è nessuna eruzione, il cratere di Krakatau e dintorni lunare, sue fumarole, le colate laviche congelati, scogliere spettacolari pomice di ciò che rimane dell'isola complesso distrussero nel 1883, hot springs, barriere coralline e tante altre attrazioni rendono questo un viaggio perfetto se volete un'estensione del vulcano fuori da Jakarta.
Fantastica ambientazione esotica di Krakatau combinato con il lusso di piacevoli bagni, spiagge, pesce fresco e ottima organizzazione dal nostro esperto equipaggio locale completano il viaggio. more info
