Blue Earth Seismology Seminar
2019-A semester (Tuesday 17:00-18:30) @ERI Bld#1-3F
Coordinator(2019 A): Yuki Kawano
Schedule:
- 9/24 short introductory meeting
- 10/1 (ERI-IPGP workshop in Paris)
- 10/8
Deep learning of aftershock patterns following large earthquakes;
DeVries et al. (2018) Nature
(reported by Ta-Wei Chang, EPS)
PDF;
additional readings:
1. Mignan & Broccadro, 2019: One neuron versus deep learning in aftershock prediction, Nature; Matter Arising
--> Arguing that the machine learning may not be necessary/ beneficial for the discussion
https://www.nature.com/articles/s41586-019-1582-8
2. Meade et al., 2017: What Is Better Than Coulomb Failure Stress? A Ranking of Scalar Static Stress Triggering Mechanisms from 10 5 Mainshock¡¾Aftershock Pairs, GRL
--> The same authors, with very similar results from essentially the same analysis without using machine learning; also cited in the paper discussed.
https://agupubs.onlinelibrary.wiley.com/doi/full/10.1002/2017GL075875
3. Fawcett et al., 2006: An introduction to ROC analysis, Pattern Recognition Letters
--> A recommended read for introductory explanation of the ROC curves, the confusion matrixes, idea of "false positive/ true negative"
https://www.sciencedirect.com/science/article/pii/S016786550500303X
4. Mallman & Zoback, 2007: Assessing elastic Coulomb stress transfer models using seismicity rates in southern California and southwestern Japan, JGR
--> A quantitative study that concludes seismicity increase is not correlated with signs of Coulomb stress changes; also cited in the paper discussed.
