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. The eruption also affected the climate and caused temperatures to drop all over the world.

How were people affected by Krakatoa?
According to the official records of the Dutch East Indies colony, 165 villages and towns were destroyed near Krakatoa, and 132 were seriously damaged. At least 36,417 people died, and many more thousands were injured, mostly from the tsunamis that followed the explosion.
What were the effects of Krakatoa eruption?
During the next 24 hours, hot avalanches of ash raced down the volcano and across the sea. Most of the volcanic island collapsed into the ocean, triggering tsunamis and creating a giant underwater crater, or caldera. The eruption devastated surrounding islands and the coast of Java, causing over 36,000 fatalities.
How does a volcano affect humans?
Fast-moving lava can kill people and falling ash can make it hard for them to breathe. They can also die from famine, fires and earthquakes which can be related to volcanoes. People can lose their possessions as volcanoes can destroy houses, roads and fields.
Why 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.
How did Krakatoa affect the economy?
A devastating tsunami in 2004 that killed 230,000 people in countries around the Indian Ocean rim, most of them in Indonesia, knocked just 0.3% off the nation's growth, although it slashed the local economy of hardest-hit Aceh province nearly in half.
Who survived Krakatoa?
Four days after the eruption, a rescue team heard Sylbaris' cries from the rubble of the prison. Although badly burned, he survived and was able to provide an account of the event.
How much damage did Mount Krakatoa do?
Official records held that 165 villages and towns surrounding Krakatoa were destroyed and 132 more were seriously damaged. Nearly 36,500 people died, and many thousands injured, mostly due to the vast tsunamis which occurred following the explosion.
What is Krakatoa known for?
Krakatoa is a small volcanic island in Indonesia, located about 100 miles west of Jakarta. 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.
What are 3 negative effects of volcanoes?
Major health threats from a volcanic eruption
Health concerns after a volcanic eruption include infectious disease, respiratory illness, burns, injuries from falls, and vehicle accidents related to the slippery, hazy conditions caused by ash.
What does Black smoke from a volcano mean?
“Black smokers” are chimneys formed from deposits of iron sulfide, which is black. “White smokers” are chimneys formed from deposits of barium, calcium, and silicon, which are white. Underwater volcanoes at spreading ridges and convergent plate boundaries produce hot springs known as hydrothermal vents.
What is the effect of volcanic eruption to humans and environment?
Among the hazards in distant areas are the effects of toxic volcanic ashes and problems of the respiratory system, eyes and skin, as well as psychological effects, injuries, transport and communication problems, waste disposal and water supplies issues, collapse of buildings and power outage.
Why was 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.
Is Krakatoa in the Ring of Fire?
Major volcanic events that have occurred within the Ring of Fire since 1800 included the eruptions of Mount Tambora (1815), Krakatoa (1883), Novarupta (1912), Mount Saint Helens (1980), Mount Ruiz (1985), and Mount Pinatubo (1991).
How many died in Krakatoa?
As the volcano collapsed into the sea, it generated a tsunami 37m high – tall enough to submerge a six-storey building. And as the wave raced along the shoreline of the Sunda Strait, it destroyed 300 towns and villages, and killed more than 36,000 people.
How does a volcano affect society?
The Effects of Volcanic Eruptions on Society. HOW DO VOLCANIC ERUPTIONS AFFECT SOCIETY? ... On longer time scales, eruptions can inject massive quantities of ash into the atmosphere, greatly reducing the solar heating of the Earth and potentially interrupting the global food supply for several years.
What happened before Krakatoa erupted?
In the years before the 1883 eruption, seismic activity around the Krakatoa volcano was intense, with earthquakes felt as far away as Australia. ... Earthquakes were felt at Anyer, Banten, and ships began to report large pumice masses to the west in the Indian Ocean.
