# easyQuake

Simplified machine-learning driven earthquake detection, location, and analysis in one easy-to-implement python package.

On most systems you should be able to simply:
```
pip install easyQuake
```
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 .
```

## Requirements
This code leverages machine-learning for earthquake detection. 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.

* Requires obspy, keras, tensorflow-gpu, basemap
* Easiest installation path includes installing Anaconda python, "conda install tensorflow-gpu" installs cudatookkit and tensorflow

## Running easyQuake
The example runs easyQuake for a recent M6.5 earthquake in Idaho

    association_continuous(dirname=dirname, project_folder=project_folder, project_code=project_code, maxdist=maxdist, maxkm=maxkm, single_date=single_date, local=True)

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


catdf = simple_cat_df(cat)
plt.figure()
plt.plot(catdf.index,catdf.magnitude,'.')
```
