The Krakatoa volcano recently erupted on the island of Anak Krakatau, Indonesia. According to reports, images captured by satellites showed the ash rising several 47,000 kilometres into the air along with SO2 emissions. The eruption was possibly the strongest since the partial collapse in 2018 that triggered a tsunami killing hundreds of people.
After the 2018 incident, researchers investigating the issue stated that the island was reduced to a quarter of its size that was there before the eruption.
Experts initially used satellite radar images to understand what happened to the volcano. Cloud cover, high seas and continuous eruptions hampered physical inspections.
According to reports, the crater peak of the volcano was at a height of 110 metres after the 2018 incident. However, a two-month old study suggested that the crater peak had a height of 338 meters.
According to Indonesia’s Centre for Volcanology and Geological Disaster Mitigation, Anak Krakatau island had a volume of 1.4 billion-2.4 billion cubic feet. The island has lost a volume of about 5.2 billion-6.3 billion cubic feet since the 2018 eruption and tsunami.
The study and analysis showcased the extent of Anak Krakatau’s collapse. It talked about the devastating tsunami that wrecked the coastline in Java and Sumatra. According to reports, more than 420 people lost their lives and at least 40,000 were rendered homeless.
Officials asked residents to stay 1 km away from the coastline of Sunda Strait, fearing the risk of another tsunami. Although, it was said that another tsunami triggered by the volcano collapsing again would not be as destructive due to its reduced mass.
Reports also state that another volcano, namely Sakurajima in Kyushu, Japan has erupted this morning. We will keep this space updated as soon as reports come in.
