Krakatoa Volcano – History, Location and Disasters!
O Krakatoa volcano today it no longer has a gigantic size as in the past, but it has already become the cause of the disappearance of the entire island and is still generating controversy about the consequences of your future eruptions.
It changes every year, affecting neighboring islands. However, it is of great interest to tourists, so they usually go on excursions and observe the volcano from afar. In addition, about 3 years ago a new disaster happened, on December 22, 2018, with his “son”, Anak Krakatoa.

Characteristics of the Krakatoa volcano
For those interested in knowing on which continent one of the most active volcanoes in the world is located, it is important to note that it is part of the Malay archipelago.
The Malay archipelago is also known as “Insulindia” and “Insulasia”, being a vast and numerous group of islands located between the continent of Southeast Asia and Australia, in the region of Austronesia.
Located between the Indian and Pacific oceans, this group of over 20.000 Islands It's the biggest archipelago of the world. The islands of the Krakatoa volcano, for example, are located in the Sunda Strait, and the volcano itself is located between Sumatra and Java.
Determining the geographic coordinates of Anak Krakatoa is not easy as it may change slightly due to systematic eruptions. Previously, the volcano was an entire island with the same name, but a powerful explosion made it disappear.
Until recently, Krakatoa was forgotten, but it reappears and grows every year. The current height of the volcano is 813 meters. On average, it increases by about 7 meters every year. The volcano is believed to connect all the islands of the archipelago, having a total area of 10,5 square meters.
The story of the greatest disaster, the ancient Krakatoa
Krakatoa occasionally spits out its contents, but there have been few powerful explosions in the story. The most catastrophic event is believed to have occurred on August 27, 1883.
Following the explosion, the cone-shaped volcano literally shattered into pieces, flying 500km in different directions. The magma flew in a powerful crater stream at an altitude of 55km.
The report said the blast force was 6 points, which is thousands of times more powerful, for example, than the nuclear attack that took place in Hiroshima.
The year of the biggest eruption will remain forever in the history of Indonesia and the entire world. And although there was no permanent population in the region of the ancient volcano Krakatoa, its eruption resulted in the death of thousands of people on the nearby islands.
The violent eruption caused a tsunami 35 meters high that covered more than one beach. As a result, the Krakatoa volcano split into small islands.
Growth of Anak Krakatoa
After the Krakatoa explosion, it was hypothesized that a new one would appear at the site of the volcano that disappeared due to the explosion that occurred in 1883. The prediction came true in 1927. Then, an underwater eruption occurred and the ash rose 9 meters, remaining in the air for several days.
After these events, a small piece of land formed by solidified lava appeared, but was quickly destroyed by the sea.
Then, a series of repeated eruptions led to the birth in 1930 of a volcano, which was named Anak Krakatoa, which translates as “Son of Krakatoa”.
The “cone” has changed position a few times due to the negative impact of ocean waves, but since 1960 it has grown continuously and has attracted the attention of a large number of researchers.
Anak Krakatoa's Last Activity
No one doubts that this volcano is either active or extinct, as it occasionally spits out gas, ash and lava. In February 2014, Anak Krakatoa manifested itself causing more than 200 earthquakes.
On December 22, 2018, the eruption of the Anak Krakatoa volcano in the Sunda Strait, Indonesia, caused the collapse of a section of the crater and a subsequent tsunami that hit the coasts of Sumatra and the Island of Java.
At least 426 people died, but the number would have been even more tragic if the tsunami had hit a city while it was still in its initial state.
The displacement of water caused by the spillage of volcanic material into the sea – 150 to 180 million cubic meters of rock and ash – would have generated a wave 100-150 meters high: if this wave had traveled in a different direction than the intake and found an inhabited coast in its path, the damage would have been even greater, if possible.
At the moment, researchers are constantly monitoring changes on the volcanic island.
Note to tourists
Even if no one inhabits the volcanic island, doubts can arise about which country it belongs to to know how to arrive at this natural creation.
In Indonesia, there is a strict ban on settling near a dangerous volcano, as well as restrictions on tourist excursions, but locals are ready to accompany those who wish to go directly to the island, or at least close to it.
No image can convey the true impression of the Krakatoa volcano, so many people scramble to get to the island to see the ash-covered stingrays firsthand, take photos on gray beaches, or explore the newly emerged flora and fauna.
To get to the volcano, you need to rent a boat. This can be done, for example, on the island of Sebesi. The rangers will not only show you where the volcano is, they will also accompany you to it, as traveling alone is strictly prohibited.
