PySTP is a Python module for connecting to STP (Seismogram Transfer Program) servers and downloading event metadata, phase picks, and waveforms triggered by seismic events.
PySTP requires ObsPy.
Clone the PySTP repository:
git clone https://github.com/SCEDC/pystp.git
Navigate to the pystp directory and run pip install . to install the pystp module in your Python environment's path.
cd pystp
pip install .
get_events - Downloads an ObsPy catalog either by event IDs or by search parameters of time window, magnitude range, and location boundaries.
get_phases - Downloads an ObsPy catalog containing phase picks.
get_trig - Downloads waveforms for one or events as a Python dictionary with event IDs as keys and ObsPy Stream objects as values.
from pystp import STPClient
client = STPClient()
client.connect() # Open a connection.
# Download a catalog.
events = client.get_events(times=[datetime.datetime(2019, 10, 17), datetime.datetime(2019, 10, 17, 23, 59, 59)], mags=[2, 4])
# Get event IDs.
evids = [ev.resource_id.id for ev in events]
# Download all CI.CLC.BH waveforms for the events in the catalog.
waveforms = client.get_trig(evids, net='CI', sta='CLC', chan= 'BH_')
# Disconnect from the STP server.
client.disconnect()
