Modified Mercalli scale of earthquake intensity I. Not felt. Marginal and long-period effects of large earthquakes. II. Felt by persons at rest, on upper floors, or otherwise favourably placed to sense tremors. III. Felt indoors. Hanging objects swing.
WebThe Richter scale is a scale of numbers used to tell the power (or magnitude) of earthquakes. Charles Richter developed the Richter Scale in 1935. His scale worked like a seismogram, measured by a particular type of seismometer at a distance of 100 kilometers (62 mi) from the earthquake. Earthquakes 4.5 or higher on the Richter scale can be ... WebJan 16, 2024 · For the increasing damage evaluation, a grade from 1 to 5 is required, whereas for the vulnerability assessment the increasing overall scale of 1 to 5 is derived from the detailed evaluation of each item based on a three-grade scale, according to the effectiveness of potentially good construction details and/or earthquake-proof systems …
