| Okay. The Richter Scale measures energy waves emitted by earthquakes. At 0-1.9 energy waves can be detected only by a seismograph. At 2-2.9 hanging objects may swing. | |

| At 3-3.9 energy waves are comparable to the vibrations of a passing truck while at 4-4.9 energy waves may break windows, cause small or unstable objects to fall. | |

| Great. This is really interesting😄 | |

| At 5-5.9 energy waves may cause furnitures to move, at 6-6.9 damage to well-built structures, severe damage to poorly built ones. | |
