+
+The `ign_sismologia` platform lets you integrate a GeoRSS feed provided by the 
+Spanish [Instituto Geográfico Nacional](http://www.ign.es/) with information 
+about seismic events like earthquakes on the Iberian Peninsula and Canary 
+Islands. It retrieves incidents from a feed and shows information of those 
+incidents filtered by distance to Home Assistant's location.
+
+Entities are generated, updated and removed automatically with each update 
+from the feed. Each entity defines latitude and longitude and will be shown 
+on the default map automatically, or on a map card by defining the source 
+`ign_sismologia`. The distance in kilometers is available as the state 
+of each entity.
+

+
+The data is updated every 5 minutes.
+
+## {% linkable_title Configuration %}
+
+To integrate the IGN Sismología feed, add the following lines to your `configuration.yaml`.
+
+```yaml
+# Example configuration.yaml entry
+geo_location:
+  - platform: ign_sismologia
+```
+
+{% configuration %}
+minimum_magnitude:
+  description: The minimum magnitude of an earthquake to be included.
+  required: false
+  type: float
+  default: 0.0
+radius:
+  description: The distance in kilometers around Home Assistant's coordinates in which seismic events are included.
+  required: false
+  type: float
+  default: 50.0
+latitude:
+  description: Latitude of the coordinates around which events are considered.
+  required: false
+  type: string
+  default: Latitude defined in your `configuration.yaml`
+longitude:
+  description: Longitude of the coordinates around which events are considered.
+  required: false
+  type: string
+  default: Longitude defined in your `configuration.yaml`
+{% endconfiguration %}
+
+
+## {% linkable_title State Attributes %}
+
+The following state attributes are available for each entity in addition to 
+the standard ones:
+
+| Attribute          | Description |
+|--------------------|-------------|
+| latitude           | Latitude of the earthquake. |
+| longitude          | Longitude of the earthquake. |
+| source             | `ign_sismologia` to be used in conjunction with `geo_location` automation trigger. |
+| external_id        | The external ID used in the feed to identify the earthquake in the feed. |
+| title              | Original title from the feed. |
+| region             | Textual description of named geographic region near to the event. |
+| magnitude          | Reported magnitude of the earthquake. |
+| publication_date   | Date and time when this event occurred. |
+| image_url          | URL to a map supplied in the feed marking the location of the event. This could for example be used in notifications. |
+
+
+## {% linkable_title Full Configuration %}
+
+```yaml
+# Example configuration.yaml entry
+geo_location:
+  - platform: ign_sismologia
+    radius: 100
+    minimum_magnitude: 2.0
