This is the Request for Comments page for the QuakeML elements '''!FocalMechanism''' and '''!MomentTensor'''.
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.

In QuakeML version 1.0, there is a triggeringOriginID in both the !FocalMechanism and the !MomentTensor elements.  Since !MomentTensor cannot exist without the corresponding !FocalMechanism and since the containing !FocalMechanism contains only information related to the !MomentTensor, this seems unnecessary.  in the case where there was both a moment tensor and a fault plane solution, two !FocalMechanism elements would be needed in any case (because the moment tensor part of the information would be different from the fault plane information).
