Where is krakatoa This is modern day krakatoa • Unlike what the film says krakatoa is actually to the west of Java and southwest of Sumatra. It is part of Indonesia

When did it erupt • Krakatoa erupted in 1883 4 times in two days , once on the 26 th of October at 17: 07, and three times on the 27 th at 05: 30, 06: 44 and 10: 02.

What damage did it do Anak krakatoa was created by the explosions. It is in the middle of the island which was partly destroyed The fourth explosion caused a giant tsunami (bigger than those created by the other three) which destroyed many coastal towns in the Saundra strait. The Tsunami managed to cause small sea level oscillations as far as the English channel

• • • 1. The explosions were heard on Rodriguez Island, 4653 km distant across the Indian Ocean, and over 1/13 th of the earth's surface. 2. Ash fell on Singapore 840 km to the N, Cocos (Keeling) Island 1155 km to the SW, and ships as far as 6076 km WNW. Darkness covered the Sundra Straits from 11 a. m. on the 27 th until dawn the next day. 3. Giant waves reached heights of 40 m above sea level, devastating everything in their path and hurling ashore coral blocks weighing as much as 600 tons. 4. At least 36, 417 people were killed, most by the giant sea waves, and 165 coastal villages were destroyed. 5. When the eruption ended only 1/3 of Krakatau, formerly 5 x 9 km, remained above sea level, and new islands of steaming pumice and ash lay to the north where the sea had been 36 m deep.

• 6. Every recording barograph in the world documented the passage of the airwave, some as many as 7 times as the wave bounced back and forth between the eruption site and its antipodes for 5 days after the explosion. • 7. Tide gauges also recorded the sea wave's passage far from Krakatau. The wave "reached Aden in 12 hours, a distance of 3800 nautical miles, usually traversed by a good steamer in 12 days". • 8. Blue and green suns were observed as fine ash and aerosol, erupted perhaps 50 km into the stratosphere, circled the equator in 13 days.

• 9. Three months after the eruption these products had spread to higher latitudes causing such vivid red sunset afterglows that fire engines were called out in New York, Poughkeepsie, and New Haven to quench the apparent conflagration. Unusual sunsets continued for 3 years. • 10. Rafts of floating pumice-locally thick enough to support men, trees, and no doubt other biological passengers-crossed the Indian Ocean in 10 months. Others reached Melanesia, and were still afloat two years after the eruption. • 11. The volcanic dust veil that created such spectacular atmospheric effects also acted as a solar radiation filter, lowering global temperatures as much as 1. 2 degree C in the year after the eruption. Temperatures did not return to normal until 1888.
