Hello,

This page describes the geojson summary format:
http://earthquake.usgs.gov/earthquakes/feed/v1.0/geojson.php

MMI "V" maps to the decimal range [4.5, 5.5)


Thanks,

Jeremy

Group,

We are seeing Mmi values coming in for earthquakes with values such as 6.02, 3.42, etc.

The MMI USGS page lists Roman numeral values from I-X. How should the feed values be interpreted to fit into the Roman numeral scale?

http://earthquake.usgs.gov/learn/topics/mercalli.php

For reference, here is the properties class as we mapped it:

    [Serializable]
    class Properties
    {
            public double? Mag { get; set; }
            public string Place { get; set; }
            public string Time { get; set; }
            public string Updated { get; set; }
            public int? Tz { get; set; }
            public string Url { get; set; }
            public object Felt { get; set; }
            public object Cdi { get; set; }
            public object Mmi { get; set; }
            public object Alert { get; set; }
            public string Status { get; set; }
            public object Tsunami { get; set; }
            public string Sig { get; set; }
            public string Net { get; set; }
            public string Code { get; set; }
            public string Ids { get; set; }
            public string Sources { get; set; }
            public string Types { get; set; }
            public object Nst { get; set; }
            public string Dmin { get; set; }
            public string Rms { get; set; }
            public string Gap { get; set; }
            public string MagnitudeType { get; set; }
    }
