Discription

OBSTransformer is a transfer-learned seismic phase picker for Ocean Bottom Seismometer (OBS) data adopted from the EqTransformer model. OBSTransformer has been trained on an auto-labeled tectonically inclusive OBS dataset comprising ~36k earthquake and 25k noise samples.

Installation

OBSTransformer is a variant of EqTransformer optimized for OBS data. Visit the parent repository for detailed installation guidelines.

To start with (anaconda):

conda create -n obst python=3.7
conda activate obst
pip install EQTransformer

You may encounter version conflicts between packages, such as numpy or protobuf. Try to install the suggested versions to eliminate the issue.
