After the severe earthquake and tsunami in Japan, the International Charter ‘Space and Major Disasters’ was activated on the morning of the 11 March 2011. All participating institutions were asked to provide satellite imagery of the affected area.
March 11, 2011 will be remembered as the date of one of the largest earthquakes and tsunamis in living history. An 8.9 earthquake, along with massive tidal waves, hit Japan with incredible force, causing catastrophic devastation. As the quake hit and the tsunami moved across the Pacific,
On October 25th 2010, an earthquake followed by a devastating tsunami struck the Mentawai Islands, a group of four large islands – Siberut, Sipora, Pagai Utara and Pagai Seletan - situated off the western coast of Sumatra in Indonesia.
“Tsunami” is a Japanese word in which “tsu” means harbor and “nami” means wave. Thus the word means “harbor wave”. Tsunami is a series of waves that can travel at speeds averaging 450 (and up to 600) miles per hour in the open ocean. Most of tsunamis are caused by earthquake even though landslides, volcanic eruptions, and even meteorites can also generate a tsunami. From an initial tsunami generating source area, waves travel outward in all directions much like the ripples caused by throwing a rock into a pond.
