Developed countries focus on technology, but lullabies can sometimes have a greater effect.
Moments after an earthquake in Palu, Friday 29 September 2018, thousands of houses and people in the area were swallowed by the ground because of liquefaction.
While the term liquafaction has only been widely discussed in Indonesia and the world in the past week, Palu's susceptibility to liquefy had already been studied.

Wildfires in the US have drawn thousands of firefighters. Meanwhile, Indonesia is struggling to rebuild in the wake of earthquakes. What's the difference? Poverty and access to resources.
A tectonic earthquake doesn't always trigger eruptions of nearby volcanoes. If an eruption happens, the volcano must already have been in a critical condition.
Thousands of houses has been destroyed by earthquakes in Indonesia.
As Indonesia reels from two deadly earthquakes, it's time to rebuild smarter and stronger.
Shallow but powerful earthquakes on Lombok have resulted in around 100 deaths and destroyed buildings.
Caught in the middle: Lombok and Bali are exposed to earthquake and tsunamis risk due to a tectonic plate boundary to the south, but also a unique zone of activity that thrusts to the north.

'Bendable concrete' is not an oxymoron. Mimicking designs found in nature, engineers are making concrete that gives under stress without shattering – an advance that could improve US infrastructure.
Earthquakes can shape political decisions so understanding them is crucial.
