There was an earthquake on the night of October 12 in the Esterhazy area with people reporting significant shaking at around 11:08 pm followed by a smaller quake 29 minutes later.
Seismic activity was recorded northeast of Esterhazy.
Mosaic’s potash operations were unaffected. Mosaic issued the following statement:
"On October 12, at approximately 11:00 p.m., a seismic event was felt near Mosaic’s Esterhazy operations. The event occurred north of Mosaic’s past mine workings.
"All employees were quickly accounted for, and comprehensive safety checks and inspections confirmed there were no reported findings. Operations at Esterhazy continue as usual, with no impact on production or infrastructure.
Power disruptions in the Esterhazy area over the long weekend were caused by the recent storm and were unrelated to the seismic event. Mosaic’s sites did not experience any outages.
"Mining induced seismic activity in this area is common, and our facilities are engineered with seismic loading in mind. This event registered well below the threshold for significant impact. While the two recent events occurred far from current mining areas and present no immediate safety concerns, we continue to advance our knowledge of the geological properties of the K3 ore body and are working with external experts to review seismic activity.
"Mosaic remains committed to transparency and safety in our operations and thanks its team members for their prompt response and diligence."
