We all know how do earthquakes occur and what destruction they cause. But as for now, we cannot predict exactly when an earthquake will happen. So the earthquake-resistant design is becoming the new form in most earthquake-prone cities. 

A nature earthquake creates motions on 3 axes, but since our shake table is moving along the same direction, it will be easy to measure the acceleration on the X-axis with a micro:bit, to give you an accurate result of how strong the earthquake is. Fix the micro:bit at the top of the building, plug it with your computer, open Mind+, and let the data fly.
