Event Intensities Pane

 

Touchstone provides visibility into and accessibility of the data behind the AIR models, in that you can 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:

       AIR Hurricane Model for the United States

       AIR Tropical Cyclone Model for the Caribbean

       AIR Tropical Cyclone Model for Mexico

       AIR Hurricane Model for the Gulf of Mexico

       AIR Tropical Cyclone Model for Central America

       AIR Typhoon Model for Japan

       AIR Typhoon Model for China

       AIR Typhoon Model for South Korea

       AIR Typhoon Model for Southeast Asia

       AIR Extratropical Cyclone Model for Europe

       AIR Earthquake Model for the United States

       AIR Earthquake Model for Canada

       AIR Earthquake Model for Japan

 

The Event Intensities feature requires a separate license.

Obtaining event intensity data can be a database resource intensive process, especially for large exposures. Consequently, please plan accordingly by allocating 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 this Hazard Analysis:

Field

Description

Can Be Included in a Template?

Event Set

Specifies the event set for which you want to obtain event intensity data during this Hazard 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 enable disaggregation when obtaining event intensity data during this Hazard 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 the application 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. Note that 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 this Hazard Analysis. Select one of the following options:

       Off

       On

       Automatic

 

Touchstone applies Average Properties automatically for certain models during Detailed Loss Analyses. Note that 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 this Hazard 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 this Hazard Analysis. To include earthquake-specific event intensity data, select this check box. 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 only applicable if the event set that you have chosen is relevant for the earthquake peril.

Yes

Peak Ground Acceleration

Specifies whether Touchstone should include peak ground acceleration (PGA) when obtaining event intensity data during this Hazard Analysis. Peak ground acceleration, 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 peak ground acceleration, select this check box. If you do not want to include peak ground acceleration, clear this check box.

Peak ground acceleration is calculated during Hazard Analysis using user-provided location data in conjunction with model data.

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

Yes

Spectral Acceleration 0.3 Seconds

Specifies whether Touchstone should include spectral acceleration (Sa) of 0.3 seconds or higher when obtaining event intensity data during this Hazard 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.

Tropical Cyclone

Specifies whether Touchstone should include tropical cyclone-specific data when obtaining event intensity data during this Hazard Analysis. To include tropical cyclone-specific event intensity data, select this check box. 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.

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

Yes

Maximum Wind Speed

Specifies whether Touchstone should include the maximum wind speed when obtaining event intensity data during this Hazard Analysis. In the context of local intensity, the maximum wind speed refers to the maximum one-minute sustained wind speed at a height of 10 meters above the ground at a location. 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.

Duration

Specifies whether Touchstone should include duration when obtaining event intensity data during this Hazard Analysis. In the context of local intensity, duration refers to the length of time during which a structure is exposed to high winds. The duration is significant because a longer duration weakens the building at a location. To include duration, select this check box. If you do not want to include duration, clear this check box.

Storm Surge Depth

Specifies whether Touchstone should include storm surge depth when obtaining event intensity data during this Hazard 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 (i.e., 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.
