Hello webservice users,

The DMC is pleased to announce the release of an update to our ws-event service. This update adds a new option to return phase arrivals, the DMC currently only has phase arrivals for the ANF catalog. Other changes include bug fixes and reorganization for compliance with the QuakeML schema.

We believe this update will be backward compatible for almost all users. Most clients, including the DMC's FetchEvent script, should require changes.

Changes:

* New 'includearrivals' option includes phase arrivals in the results. Note that the DMC only has phase arrivals for the ANF (USArray TA) catalog.

* XML name space changes (e.g. q:quakeml).

* Reorganize the Flinn-Engdahl region code and name structure to be compliant with schema (see example below).

* Fixes to radius selections near the poles. Note that radius selections can be very slow, queries become progressively slower as the search radius increases. As a work around a roughly equivalent "square" selection can be defined using the min/max latitude and longitude parameters and pruned to the desired set after retrieval.

* Refactoring of internal query logic for clarity and maintenance.


New Flinn-Engdahl region code and name structure example:

<description iris:FEcode="153">
<type>Flinn-Engdahl region</type>
<text>SOUTH SANDWICH ISLANDS REGION</text>
</description>
