These events were included in the below reports and compiled into one table. Borehole microseismic, which is deployed inside the wellbores of PPG 6X and PPG 20, is generally more accurate than surface seismic. Both systems are currently active at Sulphur Mines dome. This table going forward will be updated as new events are reported by Westlake.
