The 2004 Aceh Tsunami.
The Indian Ocean earthquake was an undersea mega thrust earthquake that occurred on Sunday, 26 December 2004, with an epicenter off the west coast of Sumatra, Indonesia. With a magnitude of Mw 9.1–9.3, it is the third largest earthquake ever recorded on a seismograph. The quake itself is known in the scientific community as the Sumatra–Andaman earthquake, resulted in a tsunami that killed 230,000 people.
I went with an emergency response team for SurfAid International into Nias in the days following this tragedy and then onto Aceh for 5 weeks helping volunteer with “Island Aid and Operation Blessing International” shooting images and handing out aid and supplies.
