Simplified machine-learning driven earthquake detection, location, and analysis in one easy-to-implement python package.
For more details, see the documentation: https://easyquake.readthedocs.io/
On most systems you should be able to simply:
pip install easyQuake
To stay on the bleeding edge of updates:
pip install easyQuake --upgrade
Or if you need to tweak something, like the number of GPUs in gpd_predict, you could:
git clone https://github.com/jakewalter/easyQuake.git
cd easyQuake
pip install .

learning to work for your regional seismic network or local earthquake study, Seismological Research

This code leverages machine-learning for earthquake detection with the choice of the GPD (https://github.com/interseismic/generalized-phase-detection), EQTransformer (https://github.com/smousavi05/EQTransformer), or PhaseNet (https://github.com/AI4EPS/PhaseNet) pickers. You should have suitable hardware to run CUDA/Tensorflow, which usually means some sort of GPU. This has been tested on servers with nvidia compute cards and modest multi-core desktop with consumer gaming nvidia card (e.g. Geforce 1050 Ti). The event-mode can be run efficiently enough on a laptop.
- Most tested configuration includes nvidia-cuda-toolkit, obspy, keras, tensorflow-gpu==2.2, basemap
- I've found that the the easiest way to install cuda, tensorflow, and keras is through installing Anaconda python and running
conda install tensorflow-gpu==2.2 - Because tensorflow-gpu 2.2 requires python 3.7 (not the latest version), you might find an easier road creating a new environment:
conda create -n easyquake python=3.7 anaconda
conda activate easyquake
conda install tensorflow-gpu==2.2
conda install keras
conda install obspy -c conda-forge
pip install easyQuake
The first example is a simple one in "event mode" - try it:
from easyQuake import detection_association_event
detection_association_event(project_folder='/scratch', project_code='ok', maxdist = 300, maxkm=300, local=True, machine=True, latitude=36.7, longitude=-98.4, max_radius=3, approxorigintime='2021-01-27T14:03:46', downloadwaveforms=True)
This next example runs easyQuake for a recent M6.5 earthquake in Idaho for the 2 days around the earthquake (foreshocks and aftershocks). The catalog from running the example is in the examples folder: https://github.com/jakewalter/easyQuake/blob/master/examples/catalog_idaho_2days.xml

#run it with EQTransformer instead of GPD picker

### IMPORTANT - must call the specific picker to create association and catalogs specific to that picker within each dayfolder!!

cat = magnitude_quakeml(cat=cat, project_folder=project_folder,plot_event=True)
cat.write('catalog_idaho.xml',format='QUAKEML')

plt.figure()
plt.plot(catdf.index,catdf.magnitude,'.')
Within your systems, consider running driver scripts as nohup background processes nohup python ~/work_dir/okla_daily.py &. In this way, one could cat nohup.out | grep Traceback to understand python errors or grep nohup.out | Killed to understand when the system runs out of memory.

Version 1.4 (9/30/2024) = Long overdue version update, including modules for PyOcto association conversion to QuakeML file and seisbench picker integration.
Version 1.3 (11/22/2022) = PhaseNet now included, in addition to GPD and EQTransformer pickers. Numerous other bugs squashed.
Version 1.2 (8/1/2022) - Rewrote the non-ML picker to be easier to work with (recursive_sta_lta from obpsy) and include input of those parameters within detection_continuous function.
Version 0.9 (2/23/2022) - Modules to cut easyQuake event waveforms from continuous data (cut_event_waveforms) and module for converting easyQuake catalog (or any QuakeML-formatted catalog) to HDF5 (quakeML_to_hdf5) for training new ML models
Version 0.8 (7/30/2021) - Several major bug fixes and improved controls for Hypoinverse location
Verson 0.6 (2/24/2021) - Implemented choice of GPD or EQTransformer pickers for the picking stage
Version 0.5 (2/10/2021) - includes embedded hypoinverse location functionality, rather than the simple location with the associator.
