A 7.5-magnitude earthquake rocked the Indonesian island of Sulawesi on September 28th followed by a massive tsunami, which killed more than 1700 people.

Without warning, a wall of water tore through the coastline of west Java and Sumatra, flattening whole communities and leaving despair and destruction in its wake.

Relief teams are on the ground aiding authorities to find the missing, clear debris and provide basic needs.

The tsunami appears to have been triggered by a combination of underwater landslides caused by the eruption of the Krakatoa volcano in the Sunda Strait that lies between the islands of Java and Sumatra.
