Mount Krakatoa is believed to be the most powerful volcano the humans have seen. While there have been many others like Mount Vesuvius and Mount Helena that were considered massive eruptions, Mount Krakatoa’s eruption was the deadliest of all.

Located on a small volcanic island of the same name in southwest Indonesia, Krakatoa was the most powerful volcano in history known to us.

The volcano erupted on August 26, 1883, and claimed the lives of more than 30,000 people. The eruption changed the geography of the island by destroying 70% of it. 

Before the volcano erupted on August 26, but intense seismic activity was observed since May 20, whose impact was felt as far as Australia. 

When the volcano erupted, its ashes reached an altitude of 6 kilometers. The sound of the eruption measured 310 dB, which could be heard 4,000 miles away. 

The energy released in this eruption was equivalent to the exploding 200 megatons of TNT. If the energy released by this volcano was compared with the Hiroshima atomic bomb, then the eruption was 10,000 times more powerful. It was also ten times more explosive than Mount St Helen’s eruption.

The island which the Krakatoa was on almost disappeared. Only a third of the island remained. Over the years, a potential volcano started forming, called Mount Anak Krakatoa. Anak Krakatoa is a potential volcano that may erupt in the future. 

Due to the impact of pyroclastic flows and volcanic ash, land near the volcano became barren and was never repopulated. Today, the area is called Ujung Kulon National Park.

The final blast in Krakatoa was pyroclastic surge (fast-flowing volcanic matter) that caused 1,000 casualties in Sumatra. 

The volcanic eruption caused tsunamis that reached as far as South Africa. The massive amount of fast-flowing volcanic material into the ocean caused these tsunamis. 

The ash from the volcanic eruption spread across the sky and lowered the average temperature of the northern hemisphere by 1.2-degree Celcius. It took almost 5 years for the weather to become normal. 

The ash clouds darkened the sky throughout the world and presented extraordinary sunsets, on which many paintings were made. The sunsets were described as vividly red and orange. Of these, the most famous painting is “The Scream” that presents the sunset in Norway. During these days, the moon appeared green and blue. 

It is worth noting that the Krakatoa volcano is located on the Pacific Ring of Fire, on which all of the strongest and deadliest volcanoes of the world are located.
