Earthquake proof buildings
Because it is so hard to detect when an earthquake is coming, scientists have made earthquake proof buildings.
These are flexible, so that the side to side movement of an earthquake doesn't affect the buildings foundations.
They are made of lighter materials, so if they do fall it will cause as little damage as possible.
They have reinforced walls so they can sway equally in both directions, wherever the earthquake tries to take them.
They have foundational cushions to absorb the shock of a quake.
Surprisingly, soil changes how bad the damage is, softer soils contain more moisture which amplifies the earthquakes movement motions so more damage happens. So, foundations are built on drier soil to be safer.
Unfortunately, not many of these buildings have been built due to high costs. But the future is bright, with more constructing materials emerging we will hopefully be seeing lots of these buildings which can resist earthquakes, especially in high risk areas.
We may not be able to stop earthquakes but at least we can prevent damage and keep as many people safe as possible.
