The Indonesian volcano which caused the tsunami that killed more than 400 people at the end of last year, has now lost more than two thirds of it’s height following its eruption, new satellite analysis has revealed.  

A part of Anak Krakatoa’s crater collapsed at the end of December after an eruption which then slide into the ocean causing a deadly tsunami.  A recent study from the Indonesian volcanic agency revealed that following this eruption the volcano has lost more than two thirds of it’s height.  At the end of 2018 the volcano which measured 338 metres now measures only 110 metres.  Researchers estimated that the volcano has lost between 150 and 180 million cubed metres of material.

“Anak Krakatoa is now a lot smaller than before. Normally you can see it’s summit from an observation point.  Now it is impossible,”  declared Wawan Irawan, the spokesperson for the Indonesian volcanic agency.

426 dead and thousands injured

According to local authorities, at least 426 people died following the deadly tsunami that swept over Indonesian coastlines on the 22 December.  However it is believed that at least 7, 202 people were injured and almost 1, 300 homes were destroyed on the west coast of Java island and the south coast of Sumatra island.  In honour of the victims, thousands of Indonesian Muslims gather in the region of Pandeglang which was severely affect by the disaster to have a collective prayer.

My prayers are with the victims that are patiently needing help,” stated Dian Rosdiana also from the Indonesian Volcanic Agency. I pray that the government will immediately start to help reconstruct our society, provide victims with clothes and food and at least provide us with some moral support.” 

Indonesia, which is positioned on the Pacific Ring of Fire (a region with high densities of volcanoes positioned near tectonic faults), is unfortunately used to this kind of disaster. In 1883 the eruption of the Krakatoa resulted in the death of more than 36,000 people in the archipelago. This eruption is the deadliest in history after the 1815 eruption of Tambora, which is also in Indonesia.  In the 19th century it is believed that almost 92,000 people lost their lives as a result of volcanic eruptions in Indonesia.
