SPYDER® data: near real-time, unQC'd,
partial data sets


SPYDER® data are event-oriented data products created shortly after an earthquake occurs. The data is unchecked and should be considered to be of unknown quality. This data comes from a variety of sources, primarily from the IRIS DMC's BUD system However, autoDRMs around the world and direct station dial-up augment the data in SPYDER®. SPYDER® data are accessed via WILBER II.

 

The FARM: delayed, QC'd, full data set
The DMC recognizes the fact that the most interesting and most frequently requested data come from major earthquakes. The most notable events are larger than a magnitude of 5.5 (Mw). For this reason, the DMC routinely pre-assembles data from earthquakes that exceed magnitude 5.7 at any depth, and for events down to magnitude 5.5 if the depth is greater than 100 km. These pre-assembled data sets are called FARM Products and consist of data collected from stations all over the world and from many different networks.

 

Tools for browsing and requesting data

 

SeismiQuery
SeismiQuery is the Web interface to our Oracle database. SeismiQuery is made up of several search utilities, including one that allows the user to create station and event files. Users are encouraged to search the database before making a request in order in ensure that we have the data of interest.

JWEED
JWeed is a map-based seismogram request tool. It enables the user to select events and stations and then download the data to their computer. JWeed is platform-independent and allows the user to access information from remote data centers, using the Data Handling Interface (DHI), and from local file sources that the user has generated and downloaded.
