Natural disasters are often staggering in their scale, but few can compare to the shocking extent of damage and life loss resulting from the 2004 Indian Ocean and the 2011 Tohoku-Oki earthquakes and accompanying tsunamis.
We have all seen the horrifying images and videos from these events. The spread of mobile phones with reasonable quality cameras means that within hours of a disaster images begin to appear on the net. For me, there is one video in particular which captures the terrifying raw power unleashed by these disasters. It was captured from on top of a solid building and shows the rapid speed and destructiveness of the tsunami. It also clearly demonstrates the huge amount of displaced water that is involved.
