11/11/2004: NCSN event waveform data are now available in SEED format. As a result, tools such as SeismiQuery and NetDC may also be used to request NCSN data.

EVT_FAST was initially developed as an interim tool for accessing NCSN data in lieu of the SEED-tools. We will continue to support EVT_FAST and have modified the interface to provide SEED and miniSEED output as well as support for SEED 'SNCL' requests.

Changes effective 2004/11/11:

By default, you will receive ALL of the waveforms for each NCSN event you request. However, you can now select a subset of channels. This channel list applies to ALL events in your request.
The waveform data channel will now be named with the approriate SEED channel names, NOT with original NSSN USGS channel names. For example, the SEED channel name EHZ refers to a 100 Hz data channel, whereas the NCSN USGS channel was VHZ.
Use SeismiQuery or the NCSN station list and NCSN station list documentation for a current list of NCSN stations and channels.

The EVT_FAST request mechanism is based on email. When you send an EVT_FAST request in an email to the NCEDC, the NCEDC extracts the waveforms for the events from its archive, converts the waveforms for each event to the specified data format, places the converted waveforms in its anonymous ftp directory, and sends you email with the URL for the waveforms. The waveforms will be in a gzipped tar file.

You may use this form to create and submit an EVT_FAST request, or you can create your own EVT_FAST request by reading the EVT_FAST documentation and emailing the request to evt_fast@ncedc.org.

Event ID selection

You may use this form to select up to 10 events.
You may find the NCSN eventids from the NCSN Catalog search
You may create your own EVT_FAST request and email it by reading the EVT_FAST documentation.

EVENTID 3:		EVENTID 4:
EVENTID 5:		EVENTID 6:

Channel selection

You may use this section to specify up to 10 distinct SEED channels selections.
If you do not specify any channel selections, you will receive ALL data channels associated with the event.
Each channel selection may use wildcard characters in the SEED network, station, channel, and location fields. Any field not specified on a partially specified line will be wildcarded.
Use a "-" or "--" to explicitly specify a blank location code.
You may use SeismiQuery. to see what data channels may be available.
