Why is the water around Krakatoa Orange?
In these areas, bubbling could be seen in the water, and where accessible, iron-rich greenish warm mud was found at the sea floor, which oxidized to orange when brought to the surface. The sea water around these areas had an intense yellow stain.
How many times has Mount Krakatoa erupted?
Thornton mentions that Krakatoa was known as “The Fire Mountain” during Java’s Sailendra dynasty, with records of seven eruptive events between the 9th and 16th centuries. These have been tentatively dated as having occurred in 850, 950, 1050, 1150, 1320, and 1530.
What would happen if Krakatoa erupted again?
At some point in the future, Anak Krakatoa will erupt again, generating more tsunamis. Since it is difficult to predict exactly which areas of the Sunda Strait will be affected, it is of paramount importance that residents in coastal villages are well aware of the danger.
Is Krakatoa a cinder cone volcano?
Krakatoa lies along the convergence of the Indian-Australian and Eurasian tectonic plates, a zone of high volcanic and seismic activity. Sometime within the past million years, the volcano built a cone-shaped mountain composed of flows of volcanic rock alternating with layers of cinder and ash.
Where was the Krakatoa volcano before it erupted?
Krakatoa Island (Krakatau in Indonesian) is a part of Indonesia and lies close to the Java Sea. It is located in between the Islands of Java and Sumatra. Before the eruption, the volcano stood 790 m above sea level. From 1927 till today, in its place now lies the Child of Krakatoa Island as a new volcano has emerged since the eruption of 1883.
What to see from the top of Krakatoa?
The view from the first peak of Anak Krakatoa (the Child of Krakatoa as the volcano is known) is impressive. Krakatoa is the tallest point in the surrounding area and from the top you can look over the blue ocean and the lush green islands that surround Krakatoa.
How big is the island of Krakatau in Indonesia?
The island of Krakatau is in the Sunda Strait between Java and Sumatra. It is part of the Indonesian Island Arc. Volcanic activity is due to subduction of the Indo-Australian tectonic plate as it moves northward toward mainland Asia. The island is about 3 miles wide and 5.5 miles long (9 by 5 kilometers).
How tall is the caldera of Krakatoa in feet?
Portions of the caldera projected above the water as four small islands: Sertung (Verlaten) on the northwest, Lang and Polish Hat on the northeast, and Rakata on the south. Over the years, three new cones were formed, merging into a single island. The highest of the three cones rose to 2,667 feet (813 metres) above sea level.
