Impact: | Combined traditional earthquake data with model-derived data (slow slip earthquakes) to better constrain the solutions to stress tensor inversions, revealing the presence of intrinsically weak fault materials in the Nankai Trough of Japan. |

Impact: | Quantified and removed a convolved signal (assumed to be GIA) within our Miller et al. (2018) dataset to reduce model error by 2%. | |

Status: | Protyping v2 and field testing. I have designed, developed, and tested positioning devices for Fairfield Nodal 5 Hz 3-component seismometers that allow users to accurately and quickly deploy nodes and quantify the sensor orientation. v2 contains an accelerometer, gyroscope, and magnetometer to quantify orientation, while v1 incorporated a bubble level and compass. |
