Volcano Eruption

 Krakatoa

 


Where is it? 

  • Rakata Island, Indonesia


When did it last erupt?

  • 2020, started in 1883


Damage it has done?

  • Krakatoa has done a lot of damage to the places and people around it. 

  • In 1833 Krakatoa first erupted. Ash fell on Singapore, Cocos Island, and ships as far as 6067 km west-northwest. Darkness covered the Sunda Straits from 11 a.m on the 27th until the next day. At least 36,417 people were killed, most people died from giant sea waves, and coastal villages were destroyed. When the eruption ended, only ⅓ of Krakatau remained above sea level and new islands formed from the magma spewing out of the volcano

  • It had destroyed and formed lands while also causing havoc for residents and other countries.



How and when was it formed?

  • Since Krakatoa lies along the Indian-Australian and Eurasian tectonic plates its how it was formed. Because the two tectonic plates are dangerous at risk of high volcanic and seismic activity it's pretty common that one was made. It supposedly started/formed in 400 BC. 



Interesting random facts?

  • the first eruption lasted one minute and 12 seconds 

  • The 1883 eruption was the loudest sounds ever reported in the history

  •  Records held that 165 villages and towns surrounding Kratatoa were destroyed and 132 more were seriously damaged 

  • Karatoa had killed 30.000+ people

  • in August 1883 was one of the most deadly  colacine eruptions in modern history, it is estimated that more than 36.00 people died. the eruption aslp affected the climate and caused temperature to drop over the world.

  • Karatoa belongs to the ring of fire

Today in science we had the opportunity to erupt our volcano. I didn't originally research about this volcano, when we first started this topic, hence why the volcano isn't Mt Tarawera. There is a video of the eruption but that will be added in to this blog poster late because we are still waiting for it to be sent.


How we made it to erupt: 

15ml of warm water

25ml of hydrogen peroxide

2 spatulas of potassium iodine into the warm water and stir.

Hydrogen peroxide food coloring and soap into the bottle that sits inside the volcano.

Warm water and potassium iodine is then added with the Hydrogen peroxide and soap which is how elephant toothpaste is made.
