This is what liquefaction looks like. It’s one of the most devastating effects of an earthquake. Soil breaks down and flows like water. It happens when a quake strikes an area with loose, moist soil that’s been shaken violently. The soil behaves like a liquid, with frightening results. Indonesian officials say more than 2,000 homes have been destroyed after a 7.5-magnitude earthquake triggered liquefaction in some areas. Here’s the village where this video was filmed. It’s located 8.5 miles from the coast. This is what it looked like before the earthquake. And this is what it looks like now. Here, we see where the houses once stood. Now, there’s nothing left. This other video shows the same phenomenon in a neighborhood in the city of Palu. It has also been largely destroyed. And here is another neighborhood that has been devastated. But liquefaction was responsible for only part of the destruction after the earthquake. On the coast, a tsunami ripped apart the infrastructure: like this bridge and this beachfront. More than 1,200 people have died and officials fear the death toll could rise as rescue teams continue their search for survivors.
