WebGround shaking during an earthquake can be enough to weaken rock and unconsolidated materials to the point of failure, but in many cases the shaking also contributes to a process known as liquefaction, in which an otherwise solid body of sediment is transformed into a liquid mass that can flow. WebIt measures the energy released during an earthquake. This is related to the amount of slip (movement) on the fault lane and the area of movement on the fault plane. MMS uses a logarithmic scale, meaning that a magnitude 6 earthquake has ten times more ground shaking than a magnitude 5. Mercalli

WebIntensity scales date from the late 19th and early 20th centuries, before seismographs capable of accurate measurement of ground motion were developed. Since that time, the divisions in these scales have been associated with measurable accelerations of the local ground shaking.
