MODIFIED MERCALLI INTENSITY SCALE: 5.9/10

Intensity class V:
Almost everyone feels movement whether inside or outdoors. Sleeping people are awakened. Liquids in containers are disturbed; some are spilled. Small unstable objects are displaced or overturned. Doors swing, close, or open. Shutters, pictures on the wall move.

Concepts and definitions

Shake Map combines instrumental measurements of shaking with information about local geology and earthquake location and mag­nitude to estimate potential impacts throughout a geographic area.
The estimated intensity map is derived from ground motions recorded by seismographs and represents Modified Mercalli Intensi­ties (MMI's) that are likely to have been associated with the ground motions.

Magnitude and Intensity measure different characteristics of earth­quakes. Magnitude measures the energy released at the source of the earthquake. Magnitude is determined from measurements on seismographs. Intensity measures the strength of shaking pro­duced by the earthquake at a certain location. Intensity is deter­mined from effects on people, human structures, and the natural environment. (Source: USGS)
