Facts and figures
What is a tsunami?
A tsunami is a giant wave. Tsunami waves can travel up to speeds of jet planes over deep waters, only slowing down when reaching shallow waters.
What causes a tsunami?
Tsunamis are caused by earthquakes or volcanic eruptions beneath the sea. As waves move closer to the shore, they become increasingly high as the ocean’s depth reduces.
What’s the Indonesian tsunami death toll?
As of Wednesday 10 October 2018, the death toll is confirmed at 2,045, and a further 5,000 people are missing. More than 70,000 people have been displaced and up to 1.5 million people have been affected.
How does it compare to the Indian Ocean tsunami 2004?
Although this tsunami is nowhere near the scale of the Indian Ocean tsunami on 26 December 2004, when nearly 250,000 people were killed, it has had a similar impact in terms of catching people unaware, destroying buildings and washing away everything in its path.
Where is Indonesia?
Indonesia is in Southeast Asia, between the Indian and Pacific oceans. It has more than thirteen thousand islands, making it the world’s largest island country.
What are the worst affected areas?
The worst affected areas are: Donggala, Palu, Parigi Moutong and Sigi, according to the latest AHA Centre report.
What is soil liquefaction?
There have been reports and footage of buildings collapsing after the Indonesia earthquake as the ground appears to slide beneath them. This is due to a phenomenon called soil liquefaction, likely caused by the earthquake. It occurs in saturated, loose soil that is suddenly shaken, causing the bond between particles to loosen. This means the soil begins to behave like a liquid, and can no longer support foundations for buildings.
