Request for Comments, QuakeML Basic Event Description, Version 1.0
["RFC_BED_1.0"] QuakeML 1.0 RFC Overview
Magnitude, Amplitude
This is the Request for Comments page for the QuakeML elements Magnitude and Amplitude. Please add comments which are related to these aspects of QuakeML at the bottom of the page. Please also give your name and the submission date.
Concerning magnitude codes, does they match the last IASPEI recommendations on the nomenclature of magnitudes. For example, QuaklML proposes Mb for bodywave magnitude. But "Mb" is different from "mb". Both exists but are not computed the same way. Moreover, MagnitudeCode maybe should not be a free-text field because this may prevent a user from seeking "all events with mb>5.0" for example. Magnitude code should be a key-parameter for data request.
- Many institutes report several magnitudes for a same event and a same origin. For example value of mb, ML and MS.
Is there a possibility to set a Preferred Magnitude somewhere like it is possible for the preferred location ?
What is the "ScalingTime" that appear in the definition of Amplitude element ?
