It first appeared to have broken the surface in 1927. It's 500 meters high and has been rising for over 50 years. Each year it grows an average of 6 meters. It is currently about 200 meters above sea level and has a diameter of 2 kilometers. </div>Meredith and Dinahttp://www.blogger.com/profile/00030563810008721363noreply@blogger.com0tag:blogger.com,1999:blog-2985942292524271832.post-24854384645874554892009-03-25T05:46:00.000-07:002009-03-25T05:54:20.261-07:00Quick Facts #2<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEh_3yNEsHPpTRXR8LN64HgJl8-F6TxjHy_m99K1XXiKV69_FLZHL9VwQifs_Bzb5tj0NBCQm-RZMaHDXp0QB-9dMO9w2aGU4nePHoAX6t62skxLgqRXwu8c0LgqOXPl1g8lcbcesmUlTOo/s1600-h/Krakatoa_01-before.jpg"><img id="BLOGGER_PHOTO_ID_5317107865761485026" style="FLOAT: left; MARGIN: 0px 10px 10px 0px; WIDTH: 320px; CURSOR: hand; HEIGHT: 214px" alt="" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEh_3yNEsHPpTRXR8LN64HgJl8-F6TxjHy_m99K1XXiKV69_FLZHL9VwQifs_Bzb5tj0NBCQm-RZMaHDXp0QB-9dMO9w2aGU4nePHoAX6t62skxLgqRXwu8c0LgqOXPl1g8lcbcesmUlTOo/s320/Krakatoa_01-before.jpg" border="0" /></a><br /><div>THE 1883 ERUPTION</div><br /><div>The sound of the eruption is thought to be the loudest sound in recorded history</div><br /><div>The sound was heard 3,000 miles away in Mauritius</div><br /><div>Nine Tsunamis were generated due to the explosion.

These clouds lasted for about two months. These clouds of ash actually impressed the locals, but the volcanoe was about to erupt. The volcanoe finally erupted August 26th, 1883 until August 27th. The eruption was one of the worst in history. The northern two-thirds of the island collapsed, generating a series of pyroclastic flows and large tsunamis. 36,417 people died in the eruption. The eruption had a V.E.I of 6, which is equivalent to 200 megatons of TNT.Meredith and Dinahttp://www.blogger.com/profile/00030563810008721363noreply@blogger.com0
