US: A magnitude-3.7 earthquake occurs near Pierre, South Dakota, May 30

A magnitude 3.7 earthquake occurred in central South Dakota at around 15:39 May 30. The epicenter was about 36 km (22 miles) north-northwest of Pierre. The tremor occurred at a depth of about 12.7 km (7.8 miles); moderate shaking was reported near the epicenter, with weak-to-light shaking experiences elsewhere across the central part of the state. There have been no initial reports of damage or casualties as a result of the earthquake; however, significant damage is unlikely. It could take several hours until authorities can conduct comprehensive damage assessments, especially in remote areas. Light aftershocks are likely over the coming days.

Officials may temporarily shut down transportation infrastructure in the tremor zone to check for damage. Minor disruptions could occur during shutdowns, but service will likely resume quickly if no damage is found. Utility outages are possible, particularly near the earthquake's epicenter.
