  2. ShakeMap - Wikipedia

    en.wikipedia.org/wiki/ShakeMap

    According to the USGS, "ShakeMaps provide near-real-time maps of ground motion and shaking intensity following significant earthquakes. These maps are used by federal, state, and local organizations, both public and private, for post-earthquake response and recovery, public and scientific information, as well as for preparedness exercises and ...

  3. Seismic microzonation - Wikipedia

    en.wikipedia.org/wiki/Seismic_microzonation

    Seismic microzonation is defined as the process of subdividing a potential seismic or earthquake prone area into zones with respect to some geological and geophysical characteristics of the sites such as ground shaking, liquefaction susceptibility, landslide and rock fall hazard, earthquake-related flooding, so that seismic hazards at different locations within the area can correctly be ...

    The U.S. Geological Survey (USGS) reported that a magnitude 5.8 M w earthquake hit Virginia on Tuesday, August 23, 2011, at 17:51:04 UTC (1:51 pm Eastern Daylight Time). The quake occurred at an approximate depth of 3.7 miles and was centered in Louisa County (location at 37.936°N, 77.933°W), 5 miles SSW of Mineral, Virginia and 37 miles NW of Richmond, Virginia's capital.

  5. Hazard map - Wikipedia

    en.wikipedia.org/wiki/Hazard_map

    Example of a hazard map. A hazard map is a map that highlights areas that are affected by or are vulnerable to a particular hazard. They are typically created for natural hazards, such as earthquakes, volcanoes, landslides, flooding and tsunamis. Hazard maps help prevent serious damage and deaths. [1]

    Map showing the epicenters of all the magnitude 5 and greater earthquakes in the eastern region of the Caribbean for the last 100 years. Filled circle color indicates depth and circle size indicates magnitude. The five biggest, most destructive, earthquakes of the last 250 years with magnitudes of 7 and greater are shown by stars.

  8. Seismic intensity scales - Wikipedia

    en.wikipedia.org/wiki/Seismic_intensity_scales

    Where an earthquake is not recorded on seismographs an isoseismal map showing the intensities felt at different areas can be used to estimate the location and magnitude of the quake. [1] Such maps are also useful for estimating the shaking intensity, and thereby the likely level of damage, to be expected from a future earthquake of similar ...

  9. Seismic hazard - Wikipedia

    en.wikipedia.org/wiki/Seismic_hazard

    Surface motion map for a hypothetical earthquake on the northern portion of the Hayward Fault Zone and its presumed northern extension, the Rodgers Creek Fault Zone. A seismic hazard is the probability that an earthquake will occur in a given geographic area, within a given window of time, and with ground motion intensity exceeding a given threshold.
