The best way to check on data availability is to use our online database access tool SeismiQuery. SeismiQuery offers several different query tools to assist the user in acquiring information about data availability as well as metadata about stations, channels, and event catalogs. This accesses information about data in the primary archive.
Another set of tools looks at our real-time data buffer (BUD) and facilitates access and analysis of the data contained there. When looking for very recent data, you might want to consult the BUD Tools page.
