Event Intensities Pane

Touchstone provides visibility into, and accessibility to, the data behind the AIR models, enabling you to view and export the underlying hazard data that Touchstone uses to calculate loss. Touchstone supports the viewing and exporting of local event intensities for the following models:

Gulf of Mexico (Offshore), United States, Canada, Hawaii

AIR Tropical Cyclone Model

Caribbean, Central America, Mexico, Australia, India, Australia

AIR Extratropical Cyclone Model

AIR Inland Flood

Japan, United States, Southeast Europe (Albania, Macedonia, Serbia), Central Europe (Austria, Czech Republic, Germany, Poland, Switzerland)

 

Local event intensities for previous model versions of the AIR Inland Flood Model for Central Europe are not supported for Germany.

AIR Coastal Flood Model for Great Britain

Coastal Flood

 

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).


Field


Description

Can Be Included in a Template?

Event Set

Specifies the event set for which you want to obtain event intensity data during the analysis. Select the desired event set.

 

For U.S. AP event sets, Touchstone obtains event intensity data only for the continental United States.

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.

 

Touchstone performs disaggregation automatically for certain models during Detailed Loss Analyses. Touchstone also performs disaggregation automatically for these models when obtaining event intensity data. For complete information about exposure disaggregation, see the Exposure Disaggregation in Touchstone guide on AIR's Client Portal.

Yes

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

 

Touchstone applies Average Properties automatically for certain models during Detailed Loss Analyses. Touchstone also applies Average Properties automatically for these models when obtaining event intensity data. For more information about these options, see Average Properties. For complete information about the Average Properties feature, see the Exposure Disaggregation in Touchstone guide on AIR's Client Portal.

Yes

Event Set Filter

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.

 

This field is applicable only if the event set that you have chosen is relevant for the earthquake peril.

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.

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.

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.
