On Saturday morning, Juiz de Fora, Brazil, recorded a seismic event with a magnitude of 2.1, as reported by the Sismology Center of the University of São Paulo (USP) and the Brazilian Seismographic Network (RSBR). This tremor was detected by seismographic stations positioned between 70 km in Vassouras (RJ) and 180 km in Bom Sucesso (MG) from the estimated epicenter. Residents reported hearing a loud bang, indicating that the earthquake might have been more perceptible than its magnitude suggests.

The event on Saturday was more powerful than a previous tremor recorded on October 5, 2025, which had a magnitude of 1.7. While sismologist Bruno Collaço from USP and RSBR stated that a magnitude of 2.1 is considered small, the perceived intensity may have been heightened due to the shallow nature of the tremor or potential connections to anthropogenic activities. Additionally, the uncertainty about whether the earthquake was a natural occurrence arises from the distance between the seismic stations and the estimated epicenter.

Despite its minor magnitude, the occurrence raises questions about local geological activity in the region and the potential impact on residents' perceptions of safety, particularly if there are concerns about future seismic activity. The report underscores the importance of monitoring seismic events, especially in areas with human activity that could influence natural phenomena.
