Krakatoa was a volcanic island. In 1883 that volcano produced a colossal eruption. This eruption drained about 10 cubic kilometers of magma from the magma chamber. The island collapsed into the space left behind, forming a depression called a caldera.
Krakatoa, or at least it was, there wasn't much left of it aferwards.
Krakatoa is a volcanic island that is part of Indonesia. In 1883, three volcanic mountains that made up a single island erupted, destroying much of the island. The remains from that eruption are also known as Krakatoa.
False. The island of Krakatoa was indeed destroyed by a massive volcanic eruption in 1883, but it did not plow itself apart, nor was it the largest volcanic eruption. When Krakatoa erupted, it blasted out so much magma, that it left an empty space in the magma chamber. This caused the volcano to collapse in on itself. Such an even is called a caldera forming eruption. The largest eruption of historic times was the 1815 eruption of Mount Tambora. Other, prehistoric eruptions have been much larger.
It is a Strato Volcano.
Not exactly. The explosions generate by the eruption of Krakatoa were enormous, but the island itself was not blown up. The eruption ejected so much magma, that the island of Krakatoa collapsed into the space left behind.
there hasn't been a eruption in 2008 yet.
Krakatoa, or Krakatau, is an uninhabited volcanic island in the Sunda Strait, between the islands of Java and Sumatra. The eruption in August 1883 caused massive tsunamis, killing more than 36,000 people on surrounding islands. After the eruption most of the island was gone. Krakatau is still very much alive and active.
On the scale that measures the size of explosive eruptions, the 1883 eruption of Krakatoa was a VEI 6. It was about 20 times larger than the 1980 eruption of Mount St. Helens and the second largest eruption in recorded history. The largest was the 1815 eruption of Mount Tambora.
Acid (highly siliceous) - much of it andesite if I recall my reading of it correctly. Krakatoa (or '~tau') is a still-active island-arc volcano above a complex, very active subduction zone.
The 1883 eruption of Krakatoa was what scientists call a caldera forming eruption. The magma that sustains volcanic eruptions comes from a magma chamber beneath the volcano. In an especially large eruption, such as the one produced by Krakatoa, so much magma is expelled that it leaves quite a bit of empty space that the magma once occupied. The volcano then collapsed into this space.
Krakatoa was loud enough to be heard almost anywhere on the planet. When it blew people within range of it where killed by the force. According to the website at the link provided below the 1883 eruption of Krakatoa was historically measured at 180 decibels. The explosion was heard 1,930 miles away in Perth, Australia and the island of Rodrigues near Mauritius 3,000 miles away.
It cost about 1.5 million dollars to repair Krakatoa's damages
