How to make an Earthquake-proof Building
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
In order to have an earthquake-proof building, it needs to have strength, flexibility, and vibration control. To have a strong building, you'll need to have a strong material, like concrete. Concrete is a strong material, but it can shake apart if an earthquake were to come along. You would also need a flexible frame to have the building bend and sway with the earthquake. Steel is a very flexible metal, it's used in frames on buildings in earthquake zones. The building needs vibration control to be complete. Without the vibration, it would survive only a short time in an earthquake. The building needs to respond to the shaking and transfer most of the energy back to the ground and keep it from shaking a lot. Reducing the shaking of the building helps too. That's all you need to make an earthquake-proof building.
THE EARTHQUAKE DETECTOR
~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Once upon a time, there was a polymath named Zhang Heng who lived in China nearly 2000 years ago. He invented the first ever earthquake detector, AKA the seismometer. It was made with a pendulum that swung in the direction of an earthquake. Wherever it swung, it would knock a ball out of one of the eight dragons mouths and into a toad's mouth below. Whichever ball dropped, that way was where the earthquake was. One day, he decided to take it into court. His rivals weren't very hopeful about the device. One time the device went off, but no one felt a thing. They all laughed at him! Later, someone came by and reported that an earthquake happened at the exact place the detector said it would.
