Frequently Answered Question


What tools can I use to request waveforms?


Web Services

All data ultimately comes from a set of web services, which can be accessed directly or through a variety of tools.


Wilber3 is a web-based tool that provides a simple map-based web browsing tool to discover data for major earthquakes. Data is drawn from preassembled data catalogs and can be plotted to the screen or downloaded as a custom data file in a number of different formats.


JWEED is a Java client that allows a user to find earthquakes, locate stations, and gain access to data using phase arrivals as time windowing operators. Data can be plotted on the screen or downloaded to disk in a number of different formats.

Standing Order for Data (SOD)

SOD is a client program that automates the process of event detection, data selection, downloading, and routine processing tasks in seismology. It allows you to define your desired data based on earthquakes, recording stations, and the resulting combination of information. SOD then retrieves the data that matches the criteria when such quakes occur.


BREQ_FAST is a way of requesting (potentially very large) sets of data by email.


WebRequest is a web-based front end for submitting BREQ_FAST requests.

Buffer of Uniform Data (BUD)

BUD is the IRIS DMC’s acronym for its real time data buffer. There are web tools to access data in this buffer as well as a SeedLink server for streaming data in near-real time.
