Relative Focal Mechanism Inversion Using Relative Polarities and S/P Double Ratios
Miao Zhang
Focal mechanisms of small earthquakes are critical for characterizing faults and regional stress. P-wave polarities and S/P amplitude ratios (e.g., in HASH) are widely used to dete…

Earthquake Source Depth Determination using Single Station Waveforms and Deep Learning
Wenda Li, Miao Zhang
In areas with limited station coverage, earthquake depth constraints are much less accurate than their latitude and longitude. Traditional travel-time-based location methods strugg…
