Indonesia 8.6 earthquake 11 April 2012

 On April 11 2012 ,434km south west of Banda Aceh , an earthquake of 8.6 occured at a depth of 22km. A tsunami warning was issued but as the movement was predominantly horizontal no significant water displacement occured and no tsunamis. Much to the relief of the citizens of the Indian Ocean rim who were just recovering from the boxing day tsunami of 2004. Large earthquakes could disturb the plumbing of volcanoes in the area such as Toba.
