Name: Peak Ground Acceleration MRP 500 years (Instrumental Intensity scale)
Display Field:
Type: Raster Layer
Geometry Type: null
Description: <DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>An earthquake hazard map provides, at any location, the value of a ground motion intensity measure (for example, horizontal peak ground acceleration, PGA) that is expected to be exceeded at least once in 500 year mean return period. The earthquake hazard maps are developed by determining the simulated ground motion intensities at every gridded location for 10,000 realizations of next-year activity of earthquake events. At each grid location, the intensities are ranked and the ground motion intensity of the mean return period of interest is recorded. The size of the finest grid is 9 arc seconds and was resampled to coarser resolutions (up to approximately 7 arc minutes) for some locations. Compiled by AIR Worldwide.</SPAN></P></DIV></DIV></DIV>
Name: Tropical Cyclone Wind MRP 100 years (Saffir–Simpson scale)
Display Field:
Type: Raster Layer
Geometry Type: null
Description: <DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>A tropical cyclone wind hazard map provides, at any location, the value of a wind intensity measure (for example, maximum 1 minute sustained wind speed for tropical cyclones) that is expected to be exceeded at least once in 100 year time period. The hazard maps are developed by determining the simulated intensities at every gridded location for 10,000 realizations of next-year activity of tropical cyclone events. At each grid location, the intensities are ranked and the wind intensity of the mean return period of interest is recorded. The size of the grid is 90 arc seconds.
