The webstp webservice gives access to waveform data for multiple networks, stations, channels,
locations, time ranges and events as well as phase information for events.
** Notice ** Waveforms for continuous data requests downloaded between March 3rd 2017 13:00:00 PST to March 7th 2017 14:00 PST are shifted by 1 second due to a bug in our archival. The issue has been fixed. Please re-run your requests made between those dates. Triggered data was not affected. Note: Requested time windows that don't fit this formula will return no data.
(timewindow / 1 / sr + 100) <= 400 * 1024 * 1024 / 4
timewindow is end-start in seconds, sr is sample rate of the channel. To see a full list of service parameters and their usage, click
