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 did the eruption of Krakatoa affect the world?
There was a lasting effect on the world's climate, too: aerosols emitted into the atmosphere by the blast led global air temperatures to drop by as much as 2.2 degrees Fahrenheit (1.2 degrees Celsius).
What were the effects of Krakatoa?
The combined effects of pyroclastic flows, volcanic ashes and tsunamis had disastrous results in the region. The official death toll recorded by the Dutch authorities was 36,417 and many settlements were destroyed, including Teluk Betung and Ketimbang in Sumatra, and Sirik and Semarang in Java.
What did the eruption of the Krakatoa cause?
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 happened as a result of the eruption of Anak Krakatau?
On 22 December 2018, a large explosion and flank collapse destroyed most of the 338-m-high island of Anak Krakatau (Child of Krakatau) and generated a deadly tsunami (BGVN 44:03). A larger explosion in December 2019 produced the beginnings of a new cone above the surface of crater lake (BGVN 45:02).
Can Krakatoa erupt again?
As the volcano collapsed into the sea, it generated a tsunami 37m high – tall enough to submerge a six-story building. ... And Indonesia has no advanced early warning system in place for volcano-generated tsunamis. At some point in the future, Anak Krakatoa will erupt again , generating more tsunamis.
Is Krakatoa a supervolcano?

Why is Krakatoa so powerful?
Originally Verbeek thought that Krakatoa was so fierce because sea water flooded into the volcano , reacting with molten lava; the build-up of pressure from the resulting steam would have led to an enormous blast. ... The best way of predicting a blast is to record seismic activity within a volcano.
Did Krakatoa cause a volcanic winter?
The explosion of Krakatoa (Krakatau) may have contributed to volcanic winter-like conditions . The four years following the explosion were unusually cold, and the winter of 1887–1888 included powerful blizzards. Record snowfalls were recorded worldwide.
What was the cost of damage from Krakatoa?
More than 2,000 died. The government estimates the costs of those two earthquakes at more than $2.4 billion . Earlier this year, Indonesia's finance ministry said it calculated the annual economic loss from disasters between 2000 and 2016 at $1.4 billion.
How long did the eruption of Krakatoa last?

How is Krakatoa monitored?
Monitoring. The monitoring system (KRAKMON) consists of a number of geophysical, gas-geochemical, and environmental measuring sites on the Krakatau island complex . All data are acquired continuously and are transmitted to the Pasauran Observatory (western Java) via digital radio telemetry.
