The Event Intensities feature is available when Hazard Analysis is enabled in the license file. Since obtaining event intensity data can be a database resource intensive process, especially for large exposures, allocate sufficient database space or apply an event set filter to select only the event intensities data that you want to obtain. |
The Event Intensities pane includes the following fields that enable you to select the event intensity data to include in the Hazard Analysis. The Display Unit (g) stands for Gravity (m/s2).

Can Be Included in a Template? |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Specifies the event set for which you want to obtain event intensity data during the analysis. Select the desired event set.
|
Yes |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Disaggregation |
Specifies whether you want Touchstone to use disaggregation when obtaining event intensity data during the analysis. To enable disaggregation, select On. To disable disaggregation, select Off.
When disaggregation is enabled, Touchstone distributes aggregate (coarse resolution) location data down to a finer resolution in locations where exposures are likely to be located based on lines of business represented in AIR's Industry Exposure Database. This process enables Touchstone to apply policy terms appropriately across an entire (distributed) region rather than applying them only across the geographic centroid of the region. Disaggregation generates hazard intensity data at a finer granularity for locations with poor quality data because it avoids analysis of aggregate exposures at a single-point location.

||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Average Properties |
Specifies how Touchstone should apply average physical properties, such as soil type and land use/land cover data, when obtaining event intensity data during the analysis. Select one of the following options: • Off • On • Automatic
|
Yes |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Displays whether Touchstone should apply event set filters when obtaining event intensity data during the analysis. To apply an event set filter, click Apply event set filter. To view, edit, or delete an applied event set filter, click View/Edit event set filter. |
No |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Earthquake |
Specifies whether Touchstone should include earthquake-specific data when obtaining event intensity data during the analysis. To include earthquake-specific event intensity data, select this check box and then select the desired earthquake-specific fields. If you do not want to include earthquake-specific event intensity data, clear this check box.
|
Yes |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Peak Ground Acceleration (Earthquake) |
Specifies whether Touchstone should include peak ground acceleration (PGA) when obtaining event intensity data during the analysis. PGA, one of the key measures of ground-shaking intensity, is the maximum value of the ground acceleration and is typically referred to as motion in the horizontal direction. To include PGA, select this check box. If you do not want to include PGA, clear this check box. The following table details the perils, display unit, and precision that Touchstone supports for peak ground acceleration for each relevant model/country:
|
Yes |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Spectral Acceleration 0.3 Seconds (Earthquake) |
Specifies whether Touchstone should include spectral acceleration (Sa) of 0.3 seconds or higher when obtaining event intensity data during the analysis. Spectral acceleration, one of the key measures of ground-shaking intensity, is the maximum response of a simple building, with a single natural frequency of vibration, to earthquake ground motions. Spectral acceleration approximates what a building experiences as modeled by a particle mass on a massless vertical rod having the same natural period of vibration as the building. To include spectral acceleration of 0.3 seconds or higher, select this check box. If you do not want to include spectral acceleration of 0.3 seconds or higher, clear this check box. The following table details the perils, display unit, and precision that Touchstone supports for peak ground acceleration for each relevant model/country:
|
Yes |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Spectral Acceleration 1.0 Seconds (Earthquake) |
Specifies whether Touchstone should include spectral acceleration of 1.0 second or higher when obtaining event intensity data during the analysis. To include spectral acceleration of 1.0 second or higher, select this check box. If you do not want to include spectral acceleration of 1.0 second or higher, clear this check box. The following table details the perils, display unit, and precision that Touchstone supports for peak ground acceleration for each relevant model/country:
|
Yes |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Tropical Cyclone |
Specifies whether Touchstone should include tropical cyclone-specific data when obtaining event intensity data during the analysis. To include tropical cyclone-specific event intensity data, select this check box and then select the desired tropical cyclone-specific fields. If you do not want to include tropical cyclone-specific event intensity data, clear this check box.
|
Yes |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Maximum Wind Speed (Tropical Cyclone) |
Specifies whether Touchstone should include the maximum wind speed when obtaining event intensity data during the analysis. In the context of local intensity, the maximum wind speed refers to the maximum wind speed sustained for one minute at 10 meters in height over model grid points (after site conditions, such as friction), measured in miles/hour. To include the maximum wind speed, select this check box. If you do not want to include the maximum wind speed, clear this check box.
The following table details the perils, display unit, and precision that Touchstone supports for the maximum wind speed for each relevant model/country:
|
Yes |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Duration (Tropical Cyclone) |
Specifies whether Touchstone should include duration when obtaining event intensity data during the analysis. In the context of local intensity, duration refers to the length of time during which a structure is exposed to high winds. The asterisk (*) in the Country/Model column in the table identifies countries/models where duration refers to the amount of time that the location of interest is exposed to winds over 40 miles per hour, a threshold at which a location will likely incur structural damage. To include duration, select this check box. If you do not want to include duration, clear this check box. The following table summarizes the perils, display unit, and precision that Touchstone supports for duration for each relevant model/country:
|
Yes |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Storm Surge Depth (Tropical Cyclone) |
Specifies whether Touchstone should include storm surge depth when obtaining event intensity data during the analysis. Storm surge depth is the level of the water above the ground at a specific point on land. The storm surge depth is the difference between the storm surge elevation (that is, the water height above normal sea level) and the land elevation. To include storm surge depth, select this check box. If you do not want to include storm surge depth, clear this check box. The following table details the perils, display unit, and precision that Touchstone supports for storm surge depth for each relevant country/model:
|
Yes |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Flood |
Specifies whether Touchstone should include flood depth when obtaining event intensity data during the analysis. Flood depth, or base flood elevation, is the elevation of surface water resulting from a flood that has a 1% chance of equaling or exceeding that level in any given year. To include flood depth, select this check box. If you do not want to include flood depth, clear this check box. The following table details the perils, display unit, and precision that Touchstone supports for flood depth for each relevant country/model:
