Welcome to SeisScan's documentation!

SeisScan is an open source Python package to detect and locate microearthquakes. This package adopts the method developed in the article Roy et al., (2024). The method leverages the signal coherence across clusters of seismic stations to generate characteristic functions that are backprojected (migrated) to detect and locate seismic events.

For a tutorial on how to use the package, please refer to the SeisScan Documentation.

Installation

SeisScan is currently running on Mac OS. SeisScan runs on Python 3.10 and up. We recommend you use the latest version of python 3 if possible.

Install via Pip

$ pip install seisscan

Install via Anaconda

$ conda create -n seisscan-env python=3.10
$ conda activate seisscan-env
$ conda install -c ksr22 seisscan

Usage

from obspy import UTCDateTime
import seisscan as ss

# Read example data
event_dict, st, inventory, subnetworks, model_name = ss.read_example()

# Extract event information
evt0 = UTCDateTime(event_dict["evt0"])    # event origin time
evlo = event_dict["evlo"]                 # event longitude
evla = event_dict["evla"]                 # event latitude
evdp = event_dict["evdp"]                 # event depth (km)

# Plot record section
fig = ss.prs(st.select(channel="DPZ"),
             evt0, evlo, evla, evdp, scale=0.1, model_name=model_name,
             xmin=0.0, xmax=6.0, width=15, height=6, handle=True)
