Seismic Phase Picking Using Convolutional Networks

IEEE Transactions on Geoscience and Remote Sensing, 2019
When a seismometer network records an earthquake, operators will manually review the waveforms and identify the wave phases, a task known as phase picking. Manual phase picking is a time-consuming process that can be automated using machine learning; however, automatic methods have not yet achieved human-level performance, and open-source ...

Automatic onset phase picking for portable seismic array observation

Acta Seismologica Sinica, 2006
Automatic phase picking is a critical procedure for seismic data processing, especially for a huge amount of seismic data recorded by a large-scale portable seismic array. In this study is presented a new method used for automatic accurate onset phase picking based on the property of dense seismic array observations.

Automated phase attribute-based picking applied to reflection seismics

open access: yesGeophysics, 2016
ABSTRACT We have applied an attribute-based autopicking algorithm to reflection seismics with the aim of reducing the influence of the user’s subjectivity on the picking results and making the interpretation faster with respect to manual and semiautomated techniques.

Transfer Learning for Seismic Phase Picking With Significantly Higher Precision in Faraway Seismic Stations

open access: yesIEEE Transactions on Geoscience and Remote Sensing
— Earthquake data recorded in Texas are dramatically different from other places because of the various types of noise caused by oil and gas production or anthropogenic activities.
