Search for Earthquake events using attribute filters

You can find Earthquake events in the stochastic catalog data that meet your specific set of event attributes.

With Catalog Viewer, you can find events in the Verisk's Earthquake model stochastic catalog that affect specific regions or pass through selected geographic areas. It also helps meet a specified set of parametric filters having a defined range of Magnitude, EQ Depth, EQ Source Type, and Fault Type. Additionally, you can add up to three different map layers as different spatial filters.

Steps to search for Earthquake events using attribute filters:

Procedure

  1. Click on the add symbol next to EARTHQUAKE
    QUERY BY search window opens
  2. Click on the Event Catalog.
    QUERY BY EVENT CATALOG search window opens enabling Select a Catalog Region and Set Event Conditions Filterset 1 options. .
  3. In the Select a Catalog Region drop-down list, select the catalog that contains the events of your interest, for example, 10k United States and Canada. From this release, Catalog Viewer is fully compatible with version 12.0 of Touchstone.
    You will get your licensed peril as the default.
  4. Click on Modify to update the Catalog Size and Model Version.
    The Modify button will be greyed out, if there is only one set of event catalogs for the peril region.
  5. Further refine your search query by selecting either the
    • Time Dependent
    • Time Independent
    Earthquake risk prespectives.
  6. Name your parametric filter set.
    1. Click on the Filterset Options
    2. Click on to Edit Set Event Conditions Name to provide a name to the parametric filter set.
    3. In the text box, type a new name for the Filterset.
    4. Optionally, click on the Clear Filterset Name to clear the text box.
  7. Specify the range for the event parameters used as filter criteria. For each parameter, you can:
    • Either manually drag the scroll bar within the desired limits.
    • Or input the maximum and minimum numerical values.
  8. Enable the Include Tsunami Event to include losses from Tsunami.
  9. Optionally, Include a Spatial Filter to specify the spatial data to be used as filter criteria:
    1. Click on the Include a Spatial Filter.
    2. From the Select Map Layer* drop-down list, select a map layer which you want to include as a spatial filter.
    3. Click on the to remove the selected map layer from the filter criteria.
    4. To include additional spatial filters, click on the another Include a Spatial Filter placed below the initial one and repeat the previous steps.

      You can add up to three spatial filters in each filter set.

  10. Optionally, to add another set of parametric and spatial filters, click on the Add a Filterset and repeat the above steps .
  11. Click the Run Query for initiating the event search.
  12. Alternatively, click on the Reset to clear all the search inputs.
  13. Optionally, select a new stochastic catalog from the Select a Catalog Region drop-down list to explore Event Ids from alternate target catalogs.

Results

The application retrieves events that meet the criteria specified in all filter sets. But for each filter set, the application searches for events that pass through any of the spatial filters.

Note: Note that whenever you navigate from one peril search to another, you will receive a warning message informing you that all of your current peril data and related map layers will be cleared.
