What is the name of a submerged volcano

Krakatau

Caldera 813 m (2,667 ft.) / Anak Krakatau: 189 m
Sunda Strait, Indonesia, -6.1 ° S / 105.42 ° E
Current status: restless (2 of 5)
Violent eruption of Krakatau showering the summit cone with incandescent bombs.

Krakatau, a small group of islands in the Sunda Strait between the islands of Sumatra and Java, is one of the most famous volcanoes in the world. It is a mostly submerged caldera with 3 outer peripheral zones and a new cone, Anak Krakatau, which has been a new island since 1927 and is still very active.
Krakatoa exploded spectacularly in a devastating Plinian eruption in 1883 that killed more than 30,000 people (mostly from the huge tsunamis that were triggered by the eruption). The outbreak was one of the first global news events after telegraph lines connected the different continents.

Typical activity: Explosive construction of an ash cone island (Anak Krakatau) within the caldera formed by the eruption of 1883. Frequent Strombolian activity.

description

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.

Expedition to observe & study the active Anak Krakatau
5-8 days - Easy
inquiry
Individual appointments possible
when erupting
Krakatau has been active again since mid-July 2011. For this reason, we offer you the opportunity to experience the eruptions of the volcano for yourself. On request, we can offer expeditions to Anak Krakatau for 1-8 people on any dates.
You will spend 3 to 5 full days near the Anak Krakatau volcano during this physically easy expedition. When it breaks out, you can marvel at spectacular fireworks from glowing boulders. We will visit various viewpoints on the volcanic island of Anak Krakatau itself and the neighboring island that surrounds it. There will also be great impressions up close from the boat. Ideal for taking pictures! This expedition in a tropical landscape will invite you to swim in the warm, tropical sea and indulge in Indonesian specialties. Our experienced Indonesian team will take care of your physical well-being.
A dream trip. We therefore recommend that you contact us soon if you are interested, as there is only a limited number of participants. more info

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.
