#GS1 #Geography #Volcano 

News : KRAKATOA volcano in Indonesia has exploded, shooting an ash column some 13km high into the air in the shocking eruption.  

  • A large magmatic eruption is taking place at the volcano right now. Based on satellite imagery, VAAC Darwin spotted a high-level ash and SO2 plume reaching 47,000 ft (15 km) altitude moving WNW. 
  • A strong thermal hot spot is detected as well. Both the webcam on Anak Krakatau Island and from the coast (in 40 km distance) show strong lava fountaining from the volcano. 
  • This seems to be the strongest eruptive phase since the violent phreatomagmatic activity following the partial collapse of the volcano on 22 Dec 2018. 

When was Krakatoa’s last eruption? 

 

 

  • The last major eruption at Krakatoa was about 18 months ago, when an eruption of the volcano on December 22, 2018 caused a deadly tsunami. 
  • Monster waves up to five meters in height made landfall, destroying hundreds of homes and killing more than 400 people. 
  • On December 31, 2018, the disaster agency gave the tsunami's death toll as 437, with 14,059 injured and more than 40,000 displaced. 
  • Following its eruption in 2018, the volcano collapsed - losing about two-thirds of its height and three-quarters of its mass. 

Where is Anak Krakatoa? 

What Made Predicting the Indonesian Tsunami Difficult | NewsClick

 

  • Anak Krakatau is a volcanic island located in the Sunda Strait between the islands of Java and Sumatra in the Indonesian province of Lampung. 
  • Anak Krakatau, which translates to "the child of Krakatoa," was formed after Krakatoa erupted in 1883. 
  • The eruption produced a massive explosion 10,000 times more powerful than the atomic bomb dropped on Hiroshima and killed approximately 36,000 people. 
  • The closest city to Anak Krakatoa is Jakarta, which lies about 100 miles from the volcano. 
  • Indonesia is often stuck by tsunamis because it sits within the Pacific Ring of Fire, which is a 25,000 miles-long chain of volcanoes and Earthquake hotbeds.
