ESM Event-Data Web-Service

The ESM Event-Data Web-Service provides machine-friendly access to event-based waveforms and response spectra included in the ESM Database.

Data may be filtered e.g. by network, station and event-id. A complete list of supported options and usage examples is available in the query-options webpage.

Feature Notes

• Waveforms and response spectra are provided by default as Adaptable Seismic Data Format (ASDF) or as a ZIP file containing DYNA 1.2 ASCII waveforms (for further details on this format, see the section "ASCII HEADER" of ESM 0.1 user manual)
• Response spectra are stored into ASDF volume in the "AuxiliaryData" structure
• Browsing ASDF volumes is possible using many software (e.g. HDFView, ASDF SEXTANT) and many programming languages (e.g. Python using modules such as pyasdf or h5py, MATLAB)
• Results are limited to 1000 data (either waveforms or response spectra) per single request
• A conversion facility to download waveforms in MiniSEED, SAC, and DYNA 1.2 ASCII formats is also provided

Backend Python software used by this web service was originally developed by Russo E. and Puglia R., and it is currently mantained by Russo E. and Felicetta C.
