- Request #147 (P. Bodin): Adding a geographic type attribute -------------------------- Basically I think etype in the AQMS schema should be a unique characteristic of an origin that specifies the physical process involved in the energy release (and which might also reflect its location technique due to the nature of the physical process). However, the current way we use 'etype' in PNSN doesn't accomplish this, because we also have etypes that are geographical in nature (i.e., 'regional', and 'teleseism'). We do have a surprising number of, for example, regional (i.e. Canadian) probable explosions. We can use either 'px' or 're', but not both. I suppose we could come up with another etype ('regional probable explosion'), but this is distasteful. So, change #1 would be to add a geographic type attribute, for which at the start we would use local (i.e. inside network), regional, and teleseism. I could also see this being useful in our historical catalog, where what is a 'local earthquake' today (say in central Oregon) was for earthquakes in 1975 (but still in the same catalog) a 'regional' event. ------------------------------------------------------------------------ ==> Approved. ------------------------------------------------------------------------
