Seismic Data

Waveform Data

The seismic can be delivered in MiniSeed or any other format compatible with Pyrocko. Qseek utilizes the Pyrocko Squirrel for fast and asynchronous data access.

To prepare your data for EQ detection and localisation, organize it in a MiniSeed file or an SDS structure.

PyrockoSquirrel Module

Waveform provider using Pyrocko's Squirrel.

Config PyrockoSquirrelJSON

environment: Path to a Squirrel environment.
persistent: Name of the persistent collection for faster loading.
waveform_dirs: List of directories holding the waveform files.
start_time: Start time for the search in ISO8601.
end_time: End time for the search in ISO8601.
channel_selector: Channel selector for waveforms, e.g. ['HH', 'EN'].
n_threads: 8: Number of threads for loading waveforms.

Meta Data

Meta data is required primarily for station locations and codes.

Supported data formats are:

Metadata does not need to include response information for pure detection and localisation. If local magnitudes M_L are extracted, response information is required.

Stations Module

Config StationsJSON

pyrocko_station_yamls: List of Pyrocko station YAML files.
station_xmls: List of StationXML files or directories containing StationXML (.xml) files.
blacklist: Blacklist stations and exclude from detecion. Format is ['NET.STA.LOC', ...].
