WebApr 10, 2024 · By describing the earthquake as negligible, you show that the earthquake was barely noticeable and only as important as your plot needs it to be. 8. Rumbling Definition A strong sound that slowly builds in intensity. A low, echoing sound travelling from a far distance. Examples WebBy Earthquake Hazards The effect of an earthquake on the Earth's surface is called the intensity. The intensity scale consists of a series of certain key responses such as people awakening, movement of furniture, damage to chimneys, and finally - total destruction. WebNo, earthquakes of magnitude 10 or larger cannot happen. The magnitude of an earthquake is related to the length of the fault on which it occurs. That is, the longer the fault, the larger the earthquake. A fault is a break in the rocks that make up the Earth's crust, along which rocks on either side have moved past each other. citizen gas indianapolis in
