Was Krakatoa the biggest explosion?
In August 1883, the eruption of the main island of Krakatoa (or Krakatau) killed more than 36,000 people, making it one of the most devastating volcanic eruptions in human history.
How did Krakatoa explode?
This eruption was caused by high pressure buildup in the two underlying tectonic plates. The resulting crack allowed for water to enter the volcano and mix into the magma cavity. This along with the extremely heated steam resulted in extremely intense pressure and an almost complete destruction of the island.
What is the most loudest volcano eruption?
The loudest sound in recorded history came from the volcanic eruption on the Indonesian island Krakatoa at 10.02 a.m. on August 27, 1883. The explosion caused two thirds of the island to collapse and formed tsunami waves as high as 46 m (151 ft) rocking ships as far away as South Africa.
What did Krakatoa look like?
Krakatoa was but a small, uninhabited island, about five miles long and three miles wide. It had two elevations, of which the taller, called the Peak of Krakatoa, rose 2750 feet above the sea. On the adjacent land are volcanic cones; some active, some slumbering, and others dead.
What made Krakatoa so loud?
In general, sounds are caused not by the end of the world but by fluctuations in air pressure. A barometer at the Batavia gasworks (100 miles away from Krakatoa) registered the ensuing spike in pressure at over 2.5 inches of mercury. That converts to over 172 decibels of sound pressure, an unimaginably loud noise.
Was Tambora louder than Krakatoa?
Tambora’s Significance Its Volcanic Explosive Index (VEI) was 7, the only confirmed rating of that intensity since the Lake Taupo eruption in New Zealand 1,600 years before. By comparison, Krakatoa earned a VEI of only 6. Further, Tambora spewed a far greater volume, at 38 cubic miles (160 cubic kilometers).
How far away was the Krakatoa explosion heard?
3,000 miles away
Heard 3,000 miles away, the explosions threw five cubic miles of earth 50 miles into the air, created 120-foot tsunamis and killed 36,000 people.

What is the child of Krakatoa called?
In early 1928 a rising cone reached sea level, and by 1930 it had become a small island called Anak Krakatau (“Child of Krakatoa”). The volcano has been active sporadically since that time, and the cone has continued to grow to an elevation of about 1,000 feet (300 metres) above the sea.
How many people died with the explosion of Krakatoa?
The eruption of Krakatoa, or Krakatau, in August 1883 was one of the most deadly volcanic eruptions of modern history. It is estimated that more than 36,000 people died. Many died as a result of thermal injury from the blasts and many more were victims of the tsunamis that followed the collapse of the volcano into the caldera below sea level.
What caused Krakatoa to erupt?
TerraSAR-X/DLR/GFZ. What had been a 340m-tall volcano was reduced in height to less than 150m.
Was Krakatoa on a hot spot during its eruption?
Hot spots are a minority of the active volcanos, but they are some of the most active. The Krakatoa eruptions were caused by the subduction of the Indo-Australian tectonic plate as it moved northward towards mainland Asia. In 1927, it emerged from under the ocean from the collapsed crater that was created during the 1883 eruption as a
Why was Krakatoa so loud compared to other volcanoes?
Why was Krakatoa so loud compared to other volcanoes? Probably because of the force produced by the phreatomagmatic (lots water hitting lots of magma) explosion. One of the theories about what happened there is a sizable submarine landslide opening the magma chamber to intruding sea water.
