Hello,
Could you please tell me whose source catalog is used in IRIS Wilber 3? Is
it USGS?
Many thanks!

Hi Januka,
Wilber uses the IRIS fdsnws-event service (http://service.iris.edu/fdsnws/event/1/) which preferentially returns data from ISC, but since the ISC catalog doesn't include recent events, it will return data from the NEIC (USGS) catalog for those.
The meaning of "recent" here can vary, depending on the publishing schedule for the ISC catalog, but it's usually about 18 months.
If you choose the "Custom Query" option in Wilber, you can select a particular catalog to use. Be aware, though, the reason the catalogs are combined is that none of them is individually complete, so you are likely to see large gaps in the data.
Cheers,
Adam

Hi Adam,
This is regarding a question I asked about the catalog from which IRIS
Wilber 3 draws source parameters and it was said it's either NEIC or ISC
depending on the availability of records. However, when I look at this
particular event for which an ISC record is not available, IRIS WILBER 3
source location is different from that of NEIC. Could you explain this
please? Wouldn't it be good to have the catalog on which the source
parameters are based be explicitly given in Wilber 3?
IRIS WILBER 3
https://ds.iris.edu/ds/nodes/dmc/tools/event/11202357
NEIC

Many thanks!

Hi Januka,
I'm not sure the reason for the discrepancies here, but event catalogs are updated frequently, and even within a record there are frequently multiple values. For instance, within the USGS record there are several different origin locations given:
https://earthquake.usgs.gov/archive/product/phase-data/us70008fi4/us/1592073892040/quakeml.xml
None exactly matches the value shown in our service, so it looks like there may be something else going on here. I will dig into this a bit more.
But our goal here isn't really to provide event data, it's just a convenient launching point for requesting seismic data. We don't have the resources (and it frankly contravenes our charter) to provide opinions or support around the actual content of the catalogs, which is one reason we don't generally expose a lot of details about this.
Cheers,
Adam
