seisclass 0.2.1

Seismic event classification package

seisclass

Seismic event classification package for identifying natural and non-natural earthquakes.

Overview

seisclass is a Python package designed to classify seismic events using machine learning models. It provides one main function:

• check_seed: Analyzes a seismic data file (SEED format) with corresponding phase file, returning a comma-separated result string: event_type,earthquake_prob,explode_prob,collapse_prob

For detailed information about the program and to cite it in your research publications, please refer to the following papers:

Usage

Basic Usage

from seisclass import check_seed
# Analyze a SEED file with corresponding phase file
result = check_seed('path/to/seed/file', 'path/to/phase/file')
print(result)

phase file format

The phase file should be in the following format:

station,channel,time,phase

where station is the station code, channel is the channel code, time is the arrival time of the phase, and phase is the phase type (e.g., P, S).
