Here is my mapping:

PUT /_river/fault/_meta
{
    "type" : "jdbc",
    "jdbc" : {
        "url" : "jdbc:postgresql://localhost:5432/gis",
        "user" : "test",
        "password" : "test",
        "sql" : [
             {
                "statement" : "select latitude as \"location.lat\",longitude \"location.lon\",zone from alarms"
            }
        ],   
        "index" : "fault",
        "type" : "alert_status",
        "schedule": "0 0/1 * * * ?"
    },
    "type_mapping" : {
              "alert_status" : {
                  "properties" : {
                        "location" : { 
                            "type" : "geo_point",
                            "lat_lon" : true
                       }
                  }
              }
        }
}

I had posted issue about creating geo_point here.
