Waveform Web Services

• Web STP is a web service version of STP, which allows users to retrieve continuous or triggered waveform data in various formats, as well as download phase data for events in the SCEDC earthquake catalog. Users can either use the form or call the service programmatically via curl or wget.
• FDSN Waveform Web Service allows users to retrieve continuous waveform data in miniSEED format. This service follows FDSN Web Service specifications (fdsnws-dataselect). Users can either use the form or call the service programmatically via curl or wget.
