What were the effects of Krakatoa eruption?

What were the effects of Krakatoa eruption?

During the next 24 hours, hot avalanches of ash raced down the volcano and across the sea. Most of the volcanic island collapsed into the ocean, triggering tsunamis and creating a giant underwater crater, or caldera. The eruption devastated surrounding islands and the coast of Java, causing over 36,000 fatalities.

What happened as a result of the eruption of Anak Krakatau?

An eruption of the volcano on 22 December 2018 caused a deadly tsunami, with waves up to five meters in height making landfall. On 31 December 2018, the disaster agency gave the tsunami’s death toll as 437, with 14,059 injured. The tsunami affected more than 186 miles of coastline in Sumatra and Java.

Was there a warning for Krakatoa?

Why does Krakatoa erupt so violently?
