The shocks are absorbed by tree crowns or transformed into subterranean beeps. There are various methods to mitigate earthquakes. And now the researchers are ready to test the first system to make vulnerable buildings 'invisible' to the shocks.
An earthquake such as the earthquake that struck Taiwan in February 2016 can be watered down or diverted in the future.
For thousands of years buildings have been provided with sheepskins, rubber membranes and ball bearings to protect them against the devastating shocks of an earthquake. But now researchers want to mitigate earthquakes before they reach us.
Earthquakes must be watered down, spread and diverted using a number of techniques. In the first instance to protect the vital infrastructure of, for example, hospitals and nuclear power stations, but in the long term, entire cities will be protected against this natural disaster.
1. Poles spread earthquake waves
The furthest are researchers with underground circles of concrete piles that are placed with an increasingly smaller gap.
If an earthquake hits the poles, the shocks are dispersed and led away and once past the inner circles, there are only a few harmless ripples left.
2. Roots and crowns gobble up the earthquake
The circles with concrete posts can protect buildings, but not entire cities. But tall trees can do that. The fluctuations of the earthquakes can propagate in the crowns of the trees.
The most powerful earthquakes require trees that are hundreds of meters high. For this you can also place gigantic windmills that absorb the shocks.
3. Earthquake is transformed into a beep
Large, perforated steel cylinders are buried and can theoretically transform the pressure waves of the earthquake into less dangerous sound waves. In the same way that you blow air into a wooden whistle.
An earthquake of magnitude 8 on the Richter scale causes a sound wave of 160 decibels, which is about the same as the bang of a shot from a hail rifle.
