    Mining-induced seismicity (MIS) is unpredictable and has the potential to be damaging; therefore, it is important to study it to gain insight into how rock damage develops in a mine. A dataset of 1906 mining-induced events was recorded at the Trail Mountain Mine (TMM). These events cluster on Panel 13, the active panel during data collection.
